NEWDOS/80 Version 2 ZAPS

        


         Introduction - NEWDOS/80, Version 2, Model I ZAPS 04/13/82
CAREFULLY STUDY chapter 11 of NEWDOS/80 documentation for instructions on how to apply zaps.

Some modules have multiple versions with the zaps different in each version. Use the verify to determine which version you have and apply the appropriate zap(a). If you have a version different from any listed (i.e., the verify(s) do not match. contact the program's distributor or Apparat). Apparat is tryin to get the program creator/maintainer/distributor to create and distribute the necessary zaps to run with NEWDOS/80, Version 2, but where this does not occur and for widely used programs, Apparat will generate any necessary zaps. if Apparat decides to generate the zaps and does not have your particular version you will be asked to send the version you have on a diskette (as a gift to' Apparat, see chapter 11) to Apparat so that Apparat may determine the appropriate zaps; Apparat will not seek out your version from another source, and will not create a zap from a paper listing.

         ******** ZAP 001 ******** 08/04/81 ******** V2M1
Mandatory zaps to Microsoft's EDIT/CMD to enable it to run with NEWDOS/80. You must maintain separate copies of this module for each of TRSDOS and NEWDOS as the module for one system is incompatible with the that for other though the files they manipulate are compatible. These changes are due to the FCB's NEXT and EOF fields being defined in NEWDOS differently than in TRSDOS. 
EDIT/CMD,38,E8    change 7E E6 7F 7E 21 FE FF CA 58 78 EE 80 87 DA 5D 78 to
                         7E 60 69 D6 01 30 01 2B 29 07 30 01 23 18 04 78

                    to   78 D6 01 30 08 18 04 EE


         ******** ZAP 002 ******** 08/04/81 ******** V2M1
Mandatory zap for PENCIL/CMD to disable the alteration of a DOS location by PENCIL. This alteration of DOS by PENCIL is not needed in either NEWDOS/80 or NEWDOS/21. 
PENCIL/CMD,00,AE    change  F3 32 9B 46 C3
                        to  F3 00 00 00 C3
Apparat has been advised that the following two zaps to PENCIL/CMD will (1) allow PENCIL/CMD to read the directory properly and (2) enable the use of MINI-DOS under PENCIL/CMD. 
PENCIL/CMD,05,60    change  58 23 22
                    to      58 00 22

PENCIL/CMD,00,61    change  54 22 16 40 21
                    to      54 00 00 00 21
This latter zap prevents PENCIL/CMD from using its own keyboard routine, thereby defaulting back to NEWDOS/80's wherein 'DFG' invoking MINI-DOS can be spotted.


         ******** ZAP 003 ******** 08/04/81 ******** V2M1
Mandatory zap to Radio Shack's programs SCRIPSIT/UC and SCRIPSIT/LC to run under NEWDOS/80 (and NEWDOS/21). The user should maintain separate copies for NEWDOS and for TRSDOS as the programs for each system are incompatible with the other system even though the files they manipulate are compatible. The first 3 changes are necessary because of the different way the PC3's NEXT and EOF fields are maintained. If you are running NEWDOS and files appear to load .short one sector, check to make sure these zapa are in. The 4th zap causes DOS' HIMEM address value in 4049H - 404AH to be used as SCRIPSIT's high memory. The 5th zap re-enables the interrupts so MINI-DOS can be invoked from SCRIPSIT.

         ******** ZAP 004 ******** 08/04/81 ******** V2M1
Optional zap to increase drive power on delay to the full one second used in older DOSs. NEWDOS/80 waits only 112 second for the the drives to attain rotational speed during power on select. If you feel the drives would perform better with the longer delay, apply this zap. 
SYS0/SYS,04 C3    change     06 80 CB     to     06 FF CB


         ******** ZAP 005 ******** 08/04/81 ******** V2M1
Mandatory zap for APL80/CMD to enable it to run with NEWDOS/80. AFL80/CMD references a routine internal to DOS that in in a different location in NEWDOS/80 than it was for TRSDOS and NEWDOS/21. 
APL80/CMD,12,74    change  21 A2 4B    to      21 B4 4B

         ******** ZAP 006 ******** 08/04/81 ******** V2M1 ********
Optional zap to EDTASM/CMD to disable the lower case to upper case conversion done by EDTASM's keyboard input routine. Most functions within EDTASM will still require upper case, but comments and operands enclosed in single quotes (for DEFM and DEFB) will accept lower case. 
EDTASM/CMD,28,El   change  FE 61 D8    to      FE 80 D8


         ******** ZAP 006 ******** 08/04/81 ******** V2M1 ********
Optional zap to EDTASM/CMD to disable the lower case to upper case conversion done by EDTASM's keyboard input routine. Most functions within EDTASM will still require upper case, but comments and operands enclosed in single quotes (for DEFM and DEFB) will accept lower case. 
EDTASM/CMD,28,E1   change  FE 61 D8    to      FE 80 D8


         ******** ZAP 007 ******** 08/04/81 ******** V2M1
This is information rather than an actual zap.
1. Where possible, the NEWDOS/80 modules have reserved zap areas. Apparat purposely did not mention them in its documentation as it did not want to draw attention to them. Users are hereby warned that Apparat will preempt these areas without preliminary notice and in its zap verifies will expect these areas to contain zeroes. Users who apply non-Apparat zaps into these areas should carefully maintain logs of what they have done to compare against future NEWDOS/80 zap& for area conflicts.
2. The DOS command ATTRIB (see section 2.3) has an additional optional parameter, LRL-xxx, not specified in that section. LRL-xxx specifies the new logical record length of records in the file where xxx is an integer between 1 and 256. This record length is used now only by DIR, but if user processing assumes a file has a given record length, some users may want the DIR display to reflect it.
3. MINI-DOS (see section 4.2) is illegal under DOS-CALL (see section 4.4). If the DPG keys are depressed while DOS is under DOS-CALL, the triple key depression will be ignored.
4. DOS command ROUTE (see section 2.43) has been altered such that existing routes are displayed only if the ROUTE command has no parameters.
5. DOS command COPY (see section 2.14), format 6 (CBF) has a new optional parameter DFO (Destination Files Only). If DFO is specified, then file contents are copied if and only if the file previously existed on both the destination and source diskette&. DFO is mutually exclusive with FMT.
6. DOS command FORMAT (see section 2.22) has a new optional parameter RWF (R&W Format).- If RWF is specified, all errors are ignored and each track is formatted once, whether or not the format actually takes. RWF is used when the user wishes to obliterate the information on a damaged diskette and doesn't have a magnet. RWF is mutually exclusive with KDN, KDD, DDSL, DDGA and PFST.


         **************** ZAP 008 ******** 08/04/81********* V2 M1
MANDATORY zap to PROFILE's module INIT to correct for a different error code returned by NEWDOS/80 and to allow for NZ error state to take precedence over C or NC state on return from 4420R call. With this change, the zapped module will still run under TRSDOS. This zap is for 3 different versions of the same module.

                 to   44 20 19 00 00 00 00 00 00 00 30 08 CD

For those interested and for come PROFILE modules, the following optional zap will reenable the interrupts so '123' and *DFG' can be used under PROFILE and NEWDOS/80.

         ******** ZAP 010 ******** 08/04/81 ********* V2M1 ********
Mandatory zap to Racet's DSH module DSHB/CMD to adjust for NEWDOS/80's requirement that a filespec's type have a maximum of 3 chars and that a filespec end with a terminator. This corrects only for the filespec DS14C/CUDPATCHPATCHPATCH such that if a user patches in a different filespec, he/she will have to apply the 03 byte at the end of that filespec.

         ************ ZAP 011 ******** 08/04/81 ******** V2M1 ********
Mandatory zap to allow VISICALC to operate with NEWDOS/80. The resulting zapped module will not run with TRSDOS or NEWDOS21; so maintain 2 different versions. This zap deals with the different handling by NEWDOS/80 of the user 25ms interrupt routines (see sections 3.8 and 3.9).

         ********* ZAP 012 ******** 08104181 ******** V2M1 ********
Optional zap to increase or decrease the sensitivity of double density diskette formatting. One of three byte patterns can be chosen, depending on the reliability of your interface, drive and diskettes. The more sensitive the byte pattern, the greater the probability a marginal diskette will fail format and the lesser the probability that having formatted successfully, the diskette will fail later (under normal careful handling). The less sensitive the byte pattern, the lesser the probability a marginal diskette will fail format and the greater the probability that having formatted successfully, the diskette will fail later. The byte patterns are:
1.E5 E5 - least sensitive during formatting. This was and is the single density standard pattern.
[Ira's note - this is 10100111 10100111 in Binary]
2.5B 5B - intermediate sensitivity during formatting. This in the TRSDOS Model III pattern.
[Ira's note - this is 11011010 11011010 in Binary]
3.6D B6 - most sensitive during formatting. This pattern strains the disk formatting and if the interface, drives and diskettes are not in first class condition, 30% or more of the diskettes will fail formatting.
[Ira's note - this is 01101101 10110110 in Binary]
Depending upon the frequency of format failures to diskette failures at other times, the user chooses which of the three 2 byte patterns to use and inserts them in the following locations, first checking that one of the three patterns in already at those locations. Each location receives both bytes, and as a check on each location, the preceding byte is F5.

         ******** ZAP 023******** 08/28/81 ******** V2M1 ********
Mandatory zap to DOS to ease some of the problems caused by the fact that NEWDOS/80 Version 1 always used a granule lockout table in the directory GAT sector whereas Version 2 many times does not, leaving that part of the GAT sector for use by the extension for the free/allocated table. Early in the development of Version 2, the rule was that if the PDRIVE specification for GPL, was greater than 2, then the lockout table was not used. Later on, the rule was changed to be if the number of lumps in greater than 60H (96 decimal) or if relative byte 60H of the GAT sector - 0FFE, then the lockout table is not used. Some code in SYS6 was not changed to reflect this rule change, causing either a lock out table to not be created or to not be properly extended when the destination diskette has more granule* than the source diskette. This change corrects this. However, users are warned that diskettes with GPL, greater than 2 (such an 8 inch or double sided, single density 5 inch diskettes coming from Version 1) converted previous to this zap may have trouble with DIRCHECK, on either Version 1 or 2, complaining thst one or more granules are locked out but free or locked out but allocated to a file. The diskettes can still be used as it is only DIRCHECK that has the problem, but sooner or later the diskettes should be re-copyied using CBF with FMT so this lockout table conflict will be straightened out and DIRCHECK will stop complaining.

2. Allow FORMAT with BDU option and format 5 COPY with FMT and BDU options to format the destination diskette even though the destination has PDRIVE TI flag M set MSDOS model III diskette). The BDU option prevents any NMOS/80 system control data from being written on the diskette during format, and thus allows the Model III diskette to copied via format 5. Warning, the resulting diskette is no more processable by NEWDOS/80 then was the source diskette; the purpose here is to allow a NEWDOS/80 format to occur as would have happened had TI flag L been set instead of H (which also implies I if for double density diskettes, see zap 031). Remember, this is not a TRSDOS Model III format.

         ******** ZAP 029 ******** 09/02/81 ******** V2M1
This is an information zap. Many people on the model 1 are having trouble initially shifting NEWDOS/80 Version 2 to a system diskette other than 35 track, single density, single sided, which is the format of the distribution diskette. For this discussion, you are assumed to have read chapter 12 and sections 2.14 and 2.37.
1. To make a double density, single sided NEWDOS/80 Version 2 system diskette.
1. You must have an excellent working Percom or LNW double density modification in your expansion interface.
2.Take the NEWDOS/80 NEWDOS/80 Version 2 master diskette or an exact duplicate of it, place a write protect tab on it, place it in drive 0 and press RESET to bring up the system to NEWDOS/80 READY, responding with date and time if necessary.
3.Execute the DOS command:
COPY,0,0,,USD,FMT,DPDN=6
The SYSTEM and SOURCE are both the diskette with the write protect tab on. The DESTINATION diskette is the diskette to contain the double density, single sided NEWDOS/80 Version 2 system. If you have two drives available, you may use the command COPY,0,1,,USD,FMT,DPDN=6 instead. If the destination drive is not a 40 track drive, then use COPY,O,dn2-tc2,,USD,FMT,DPDN=6 where dn2 is the destination drive number and tc2 is one less than the number of tracks for that drive (i.e., 34 for 35 track drive and 79 for an 80 track drive)(example, COPY,0,1-79,,USD,FMT,DPDN=6). Further, if the destination drive has more than 40 tracks, that drive must be other than drive 0 during the COPY (otherwise you must obtain a special system diskette from Apparat at an extra charge)(after the COPY is over, you may shift that drive back as drive 0 to use it as the system drive).
4.When the COPY command completes successfully and the system has returned to NEWDOS/80 READY, mount the destination diskette on drive 0 and press RESET.
The NEWDOS/80 system on that double density, single sided diskette is now the system.
5.Perform a DIR 0 command to ascertain the extra granules are available. Then execute PDRIVE,0 to observe that the specifications for drive 0 are now single aided, double density with track 0 reserved for opposite density. Please note that the specifications for drives 1 through 9 have not been changed. If they are to be changed, you must do it, studying carefully the PDRIVE command, see section 2.37
2. To make a double sided, single density NEWDOS/80 Version 2 system diskette.
1.Make a copy of the NEWDOS/80 Version 2 master diskette. When done, mount that copy of the NEWDOS/80 Version 2 system in drive 0 and press RESET.
2.Execute the following DOS command:
PDRIVE,0,6,TI=A,TD=C,TC=40,SPT=20
This changes the specifications for drive 6 to be 5 inch, single sided, single density, 40 tracks. If you wish other than 40 tracks, change the TC parameter above to the desired track count.
3.Place a write protect tab on the system diskette you have just changed.
4.Execute the following command:
COPY,0,0,,USD,FMT,DPDN=6
The source and system diskettes are the same and are the one with the vrite protect tab. The destination diskette is the one to contain the double sided, single density NEWDOS/80 Version 2 system. If you have two drives available, you may use COPY 0,1,,USD,FMT,DPDN=6 instead. The destination must be on drive 1 if it is to have more than 40 tracks (when the COPY in finished, that drive can be made drive 0).
5.When the COPY command has completed successfully and returns to NEWDOS/80 READY, mount the destination diskette in drive 0 and press RESET to bring up the double sided, single density system. Perform DIR 0 and PDRIVE,0 as discussed above to observe the changed system. Proceed with additional PDRIVE re-specifications, if necessary.
3. To make a double sided, double density NEWDOS/80 Version 2 system diskette.
1.You must have an excellent working Percom or LNW double density interface in your expansion interface.
2.Proceed as for single sided, single density discussed above excepting that the PDRIVE command is:
PDRIVE,0,6,TI=CK,TD=G,TC=39,SPT=36,GPL=2,DDGA=2
This is for a 40 track drive, for 35 use TC=34, for 80 use TC=79.
Further:
1. For a destination drive more than 40 tracks use GPL=8 and you will probably want an expanded directory, say DDGA=6 for maximum size, giving 224 directory entries. However, if any of GPL, DDSL or DDGA are different between the source and destination drives during COPY or if the number of sectors, granules or tracks for the destination diskette is less than the source diskette, the CBF (Copy By File) parameter must be specified in the COPY command (example: COPY 0,0,,USD,FMT,DPDN=6,CBF). So, in the case here for driven over 40 tracks, since the GPL is different (the source's GPL is 2 and the destination's GPL in now 8), you must use the CBF parameter. Actually, you could have used the W option in any of the COPY's mentioned above in this zap, but CBP runs slower and should only be used where necessary.
2. For LNW interface, you can specify TI flag E instead of flag C (example, TI=EK instead of TI=CK, if any 8 inch drives are to be used with the LNW, E must be specified instead of C). However, remember, flags E and C are interdrive mutually exclusive; so if you change one of the 10 drive specs from using flag C to using flag E, you must change any of the others that use flag B or C (see next section).
3. Users setting up their systems to use the 8 inch drives through the OMIKRON interface (TI=BH) are experiencing trouble with the PDRIVE error code **** TISPEC BETWEEN DRIVES INCOMPATIBLE. Please refer to the last two sentences of the TItypel paragraph in the middle of page 2-34. If any drive's TI specifies flag B, then no other can specify either flag C or E. You must change the PDRIVE specifications for drives 4, 6, 8 and 9 an they conflict with flag B. To do this, simply execute the DOS co~nds 
PDRIVE,0,4=0
PDRIVE,0,6=0
PDRIVE,0,8=0
PDRIVE,0,9=0
Remember, you should not make any PDRIVE changes to the NEWDOS/80 Version 2 matter diskette; perform the changes on working copies of it.


         ******** ZAP 030 ******** 09/02/81 ******** V2M1
This is an information zap.
1. Chapter 12 failed to make it clear that though disketteg are content interchangeable under NEWDOS/80 Version 2 between the Model I and Model III, there is a problem dealing with a format control byte for directory sectors of single density diskettes. Carefully read SYSTEM options BK and BN (even though you have only Model III) on page 2-49, WRDIRP command on page 2-52 and the W function of DIRCHECK on page 6-14.
1.For Model III NEWDOS/80 Version 2 users, single density diskettes coming from the model 1 can be processed on the Model III by setting SYSTEM option BK-Y, setting up the proper single density PDRIVE and then for each such diskette, execute once either the DOS com-nd WRDIRP or the W function of DIRCRECK. After this is done, the diskette can be used as any other diskette under Model III NEWDOS/80 Version 2. Subsequently, this diskette can not be processed by the Model 1 TRSDOS 2.3, but it can be processed by the Model 1 NEWDOS/80 Version 1 provided the format of the diskette is not changed to one of the variety of formats available on Version 2 but not available on Version 1). However, once this diskette is used back on the Model I NEWDOS/80 Version 1 and a directory sector is updated, the diskette cannot be reused on the Model 111 without performing again the WRDIRP or DIRCHECK function on that diskette on the Model III (remember, NEWDOS/80 Version 1 does not have either of these two functions).
2.For users that have NEWDOS/80 Version 2 for both the Model I and III and wish to use single density 5 inch diskettes interchangeably between the model 1 and model III, set SYSTEM options BK-Y and BN-Y on the Model 1 and BK-Y on the Model III. Then, for each such single density diskette, execute once either WRDIRP or the W function of DIRCHECK. This can be done on either the Model I or III and all such diskette* do not have to be done at the same session. Each such diskette can now be used interchangeably between the Model I and Model III under NWOS/80 Version 2 (don't forget the proper PDRIVE specifications), but the diskette cannot be processed by TRSDOS 2.3
2. For BASIC function RENUM (see section 7.9 on page 7-5) the 4th and 5th formats listed ( RENUM X and RENUM U,X ) are not valid and should be deleted from the middle of page 7-5. If the X parameter is to be used, it must be done via the 1st format listed as X is meaningless unless specific values for ppppp and/or qqqqq are also specified.
3. Some users have asked for more distinctions between full diskette COPY (format 5) or Copy By File COPY (format 6), both specified in section 2.14.
1. Format 5 copies a full diskette sector by sector and is generally faster than format 6, which copies files individually. However, if the source diskette in relatively empty, format 6 may be faster.
2. In format 5 the source directory becomes the destination directory, including the same size and relative sector position on the diskette, while in format 6, the two directories are considered separate just as in a format 1 through format 4 COPY.
3. Generally, if format 5 is used, both the source and destination PDRIVE specifications for GPL, DDSL and DDGA must be the same (though only the restriction on GPL is enforced, but not if BDU is specified); the other PDRIVE parameters may be different provided the destination diskette is to have atleast as many sectors as the source diskette (though the format 5 specifications say that sectors per track must be the same; this is not so in Version 2 where it was in Version 1).
4. Format 5 with the BDU option allows some alien diskette& to be copied that otherwise could not be copied.
5. Format 6 allows a diskette's contents to be copied between diskettes having a different number of granules per lump (GPL), the directories positioned differently on the diskettes, the directories of different sizes, or the destination diskette having less sectors than the source.
6. Format 6 copies all of a source diskette's files or a selected subset of those files.
7. Both format 5 and 6 allow the option of formatting the destination diskette UMT) or not (NFMT). Formatting a diskette magnetically init ializes the entire diskette including the inter-sector control bytes used only by the drives and the controller. Many users prefer to do this everytime a back up is done. Of course, formatting a diskette destroys the previous contents.
8. If format 6 is being used to copy a NEWDOS/80 Version 2 system diskette, the FMT option must be specified. This assure& the correct BOOT, SYSTEM and PDRIVE control informat is stored on the destination diskette, and the correct positioning of SYSTEM files which, excepting for BOOT/SYS and SYS0/SYS, are all positioned on the destination diskette in came posi tion relative to the directory that they are on the source diskette.
9. In format 6 where NFMT is specified, system files are NOT copied to the destination diskette if they are not already existing in the destination directory. This is because system files usually use specitic FDE& in the directory, and only YMT can assure that these FDE# are available.
10. Format 5 without BDU and format 6 with FMT both assume the possibility of the destination diskette being used later as the system diskette and the destination drive or one like it being used later as drive 0; therefore both initialize the BOOTISYS file to contain the proper BOOT code and drive 0 PDRIVE specifications.


         ******** ZAP 031 ******** 09/06/81 ******** V2M1
Mandatory zap to DOS to allow files to be copied from and to diskettes used by Model I TRSDOS 2.3B and higher as well as from and to diskettes used by Model III TRSDOS 1.3 or higher. After applying the documentation changes given below, see section 12.5.1 on page 12-7, the 'flag M' paragraph on page 2-35 and the bottom half of page 2-15.
This enhancement expands the definition of PDRIVE TI flag M (see page 2-35). When the M flag is specified and the TD field specifies double density (i.e., TD=E), the PDRIVE specification is assumed for a Model III TRSDOS diskette and TI flag 1 is implied (see example 3 on page 2-38). When the M flag is specified and the TD field specifies single density (i.e., TD=A), the PDRIVE specification is assumed for Model I TRSDOS 2.3B or higher diskette, and TI flag I in not implied and must not be specified (see example 1 on page 2-38 with TI-AM).
Radio Shack has started distributing certain new programs (i.e., COBOL) with or on Model 1 TRSDOS 2.3B or higher diskette& with that system being somewhat different than Model I TRSDOS 2.3, including the use of RBAs an discussed in section 12.1 for the Model III. These diskettea are NOT compatible with NEWDOS/80 diskettes, and, as with Model III TRSDOS diakettes, COPY is the only function of NEWDOS/80 that can be used with the Model I TR5DOS 2.3B diskettes (though FREE and DIR (except EOF and special flags) appear to work).
Files on either Model III TRSDOS or.Model 1 TRSDOS 2.3B diskette* that are to be used either by NEWDOS/80 or user programs executing with NEWDOS/80 must be copied to NEWDOS/80 diskettes. FORMAT or COPY with FMT option cannot be used to format a diskette in either the Model III TRSDOS or the Model I TRSDOS 2.3B format; however, format 5 COPY with the BDU option can be used to make copies of those diskettes.
ZAP 013 must NOT be installed in a NEWDOS/80 to be used to copy Model I TRSDOS 2.3B files. ZAP 013 must be used for Model III TRSDOS 1.1 & 1.2 diskettes.
Insert the following notes in the outside margin of the specified paragraph:
1. Page 2-9, next to last paragraph: "For Model III TRSDOS and Model 1 TRSDOS 2.3B diskette&, see ZAP 031."
2. Page 2-15, "The COPY command" paragraph: "This section applies also to standard 35 track, single aided, single density diskette* for Model I TRSDOS 2.3B or higher."

Mandatory zap to DOS to correct a directory clobbering error that occurs when either CLOSE or KILL frees up a FPDE or FXDE that occupies the first PDE slot in a directory sector. This error wan missed during BETA testing as it was caused by a late adjustment to handle the TRSDOS Model III diskette&. A few persons were complaining about directories being clobbered, but only on September 12th was an error report made that lead to the discovery. Though the problem would appear to affect many users, apparently to date it has not.

Optional zap to Model I SCRIPSIT to eliminate the 'hang' occuring when the END function is executed and the last disk I/O was to a double density drive. SCRIPTSIT execute& the END function by jumping to location 0, causing a software but not a hardware RESET.
The double density modifications to the expansion interface require a hardware RESET to reset them to the single density disk I/O assumed by the software RESET in the ROM. SCRIPSIT uses the RESET to restore the keyboard, display, printer and other interface# it has changed.
If the Z-80 HALT instruction is executed instead of a jump to location 0, the Model I (this does not hold for the Model III) hardware RESET is triggered which in turn triggers the software RESET. In both cases, either the jump to 0 or the HALT, the red lights on the disk drives must be off. The zap is applicable under TRSDOS as well as all versions of NEWDOS.

Information and manual corrections.
1. A number of users have had trouble with tape 110 under NEWDOS/80 Version 2. Some of the early copies of NEWDOS/80 Version 2 had errors due to undetected RAM errors during duplication and in maybe an many as 20 cases this affected the EDTASM or LMOFFSET module. However, if these modules were bad, they usually also had problems with disk I/O as well as cassette I/O and so if disk I/O works fine, we assume it is not a bad copy of NEWDOS/80.
Tape I/O has long history of trouble, varying from computer to computer and especially from tape unit to tape unit such that any particular tape will fail on somebody's cassette unit.
This has always been an exasperating problem and the main reason why cassettes are not used at Apparat (though we do act as a retailer/distributor for products distributed on cassettes produced by others). Because cassettes are not used at Apparat, NEWDOS receives very little testing with cassettes, and in the future we are considering withdrawing all support (i.e., LMOFFSET and EDTASM) from cassettes. Cassette support for EDTASM for the Model III has already been withdrawn and will probably soon be withdrawn for the Model I (since the purpose of our EDTASM was to give disk support, not cassette).
For now though, we will restrict our error study to those problems presented to us on a diskette containing the actual NEWDOS system used. If the user presents us with a cassette along with the diskette we will test that as well; otherwise we will test with simple programs from disk in-house. Neither the diskette nor the cassette will be returned to the user. Lastly, if you can avoid use of cassettes, DO!!!!!
2. The specifications for ROUTE using the MM=addr1 operand are in error in the manual.
A. Page 2-43, 3rd paragraph, 3rd line, change "12" to "16".
B. Same paragraph, 5th line, change "13th" to "17th".
C. Page 2-44, top line, change "0FE8CH" to "0FE90H".
3. A number of users has asked why Automatic Density Recognition (ADR) was not used in NEWDOS/80 Version 2.
We wanted to included ADR but found it impractical unless we limited or expanded other capabilities made available by PDRIVE. Since we were already two months late in releasing Version 2, we decided to release without it.
Part of the problem is in providing a second SPT parameter and an extra indicator for track 0 useage (remember, Version 2 operates with double density diskettes that may or may not have track 0 reserved for single density). We also felt that if we included ADR, we should also include ASR (automatic side recognition). For now, we will remain without ADR and ASR, but will not rule it out for a subsequent NEWDOS/80 version.
4. For BASIC CMD "0" and multi-dimensional arrays, a few users have asked for clarification of term REN used in the documentation for on pages 7-14 through 7-17. CMCC does not care whether an array is single or multi-dimensional as CMD'V' only concerns itself with the relative positioning in main memory between array elements and not with the actual subscripts for a given element, except for determining the main memory position of the first element participating in the sort as specified in the CMD "0" statement.
As an aide to the programmer to understand the sort order, a formula was given for two and three dimensional arrays to determine the REN of any array element given its subscripts.
The following working BASIC program demonstrates the relationship between REN and subscripts for a three dimensional array, using Rl, R2, R3, Xl, X2 and X3 to correspond with the useage at the bottom of page 7-14 and top of page 7-15.
10 R1=3: R2=4: R3=2: DIM A(R1,R2,R3)
20 REN=0: FOR X3=0 TO R3: FOR X2=0 TO R2: FOR Xl=0 TO R1 'CREATE ARRAY IN REN ORDER
30 IF REN <> X1 + X2 * (R1+1) + X3 * (R1+1) * (R2+1) THEN PRINT"ERROR": STOP
35 ' THE ABOVE ASSURES THE FORMULA COMPUTES TO THE CURRENT REN NUMBER
40 A(X1,X2,X3)=REN: REN=REN+l: NEXT X1, X2, X3 'STORE THE REN NUMBER IN THAT ELEMENT
50 CMD"O",0,A(0,0,0) 'SORT ARRAY IN ASCENDING NUMERIC ORDER
60 ' THE ARRAY ORDER SHOULD NOT RAVE BEEN CHANGED.
70 FOR X3 = 0 TO R3: FOR X2 = 0 TO R2: FOR Xl = 0 TO R1 'LIST ARRAY IN SAME ORDER STORED
80 PRINT A(X1,X2,X3);: NEXT X1, X2, X3 'AND THIS SHOULD BE ALSO THE SORTED ORDER

Elements with one or more zero subscripts do participate in the sort if that element is within the main memory range of elements sorted, i.e., has a REN greater than or equal to the REN of the lat sort element and less than or equal to the REN of the last sort element.


5. Correct the last paragraph of page 2-27 by deleting the 3rd sentence and changing the 4th sentence to read "Hex codes less than 20H or greater than the SYSTEM option AX value will be displayed as periods.".


6. A number of users having CPU speed up modifications in their computers and setting the slow-down-during-I/O switch have complained that NEWDOS/80 continuously toggles the fast/normal CPU speed state (in many cases a light flickers on/off or red/green).


Indeed this is true. In the original TRSDOS,there were 8 interrupts, 0 - 7, of which only 6 and 7 were used.


Interrupt 6 only read the disk controller status register; so NEWDOS/80, to save resident DOS space which is critical, combined interrupt 6's function with interrupt 7,reading the controller status register every 25 ms interrupt.


Though the fast/normal CPU toggling is interested only in the controller command register,the hardware connection actually toggles on both the read of the status register and the write of the command register.


Normal disk I/O cannot operate without the statue register read when the controller has interrupt status; so we cannot eliminate the interrupt 7's read of the status register without re-enabling interrupt 6 and we don't have the patch space for that.  Therefore, users must turn off the switch on their computers that allows the fast/normal toggling to take place, and simply use the fast speed all the time (be sure SYSTEM option BJ is set correctly).  There is no guarantee that your computer will actually work at the faster speeds.  Doubling the CPU speed seems OK; tripling appears NOT.  The LNW computer at 2.5 times the TRS-80's normal speed is reported by LNW to work fine.

1. Users must remember that the Model I TRSDOS 2.3B or higher and Model III TRSDOS 1.3 or higher, amongst other things, both went to using RBAs in the NEXT and EOF fields of the FCB, thus intentionally or unintentionally restablishing compatibility with NEWDOS 2.1 and NEWDOS/80 in the use of those two fields (which many user programs use), even though the EOF fields in the directories (which most user programs don’t use) are now incompatible. Though files from those systems must be copied to NEWDOS diskettes, assembly language programs upgraded to run with those TRSDOS systems are more like to run with NEWDOS without change then they were before. For example, on the Model III, SCRIPSIT Version 3.2 has been found to work as-is. So, before calling Apparat to see if zaps exist for a given program, try it out, giving special attention to the file I/O.

											
2. The manual failed to explain that when SYSTEM option AJ=N or when the up-arrow key is held down during reset/power-on, DOS loses the ability use the lower case driver (Model I only) or to actually input keyboard characters from the chain file during chaining as these functions depend upon DOS's keyboard intercept routine being enabled. SYSTEM options AU=N and BF=N (Model I only) and are also forced. DOS will think it is activating chaining, but actually the input characters will continue to come from the keyboard; the DOS READY prompts will not be seen as DOS thinks it is chaining. For LCDVR (Model I only), the command will execute but the key input functions for lower case drive will not be done. Insert the note "see ZAP 051, part 2" in the outside margin at the following places in the manual.

											
A. Page 2-7, the "CHAINING is discussed" paragraph.

											
B. Page 2-29, the "In NEWDOS/80" paragraph.

											
C. Page 2-47, the "AJ=yn" paragraph.

											
D. Page 4-9, the "If a DOS recognized" paragraph.

											
3. Chain files must always have a name-extension. When creating a CHAIN file, you must always specify a name-extension in the filespec, excepting that CHAINBLD/BAS will assume name extension /JCL if you don’t give one. If the filespec given in a DO or CHAIN command does not specify a name-extension, then /JCL is assumed; therefore it is recommended that the name-extension /JCL be used on chain files when created. Place the note "See ZAP 051, part 3" in the outside margin in the following places in the manual.

											
A. Page 2-7, the "When the system" paragraph.

											
B. Page 4-8, the "Chain file creators" paragraph.

											
4. For Model I SCRIPSIT where the user wishes to use tape I/O, the user must back off the last zap of ZAP 003 (the SCRIPSIT/xx,00,C3 zap) in order that interrupts will remain disabled, a requirement for Model I tape I/O. This means the user cannot invoke MINI-DOS from SCRIPSIT.
