Help categorize the TRS-80 software archive

Nearly 30,000 programs, and almost none of them say what kind of program they are. Mark whatever you recognize. Pick as many words as fit — a game that teaches arithmetic is Game, Math, Education — then send the page. Everything is reviewed by hand before it goes anywhere near the archive, so a best guess is worth more than a blank.

Important Note: Do not do multiple entries of the same program. If you flag Super Nova by Big Five once, all Super Nova by Big Five entries will get updated. No need to waste your time flagging each Super Nova

DOSPLUS 3.2 or 3.2D The flagship of the Micro-Systems line. This is the BEST disk operating system currently available. It offers you all the features you could ever use, speed, reliability, and much more! Full support of variable length records. No more internal errors during file handling due to poorly written operating systems. Allows use of ISAM technique. Supports 35-80 track drives. The two operating systems are basically the same. However, Dosplus 3.2D will operate double density. The double density DOS has some differences peculiar to double density operation. Both systems offer DOS commands from BASIC, BASIC renum, and BASIC program compressor. DOS utilities include a sector display/modify program, a utility to purge files, AND a utility to restore purged or killed files. Free space map and the most comprehensive directory on the market. Try it and you'll never use anything else. All this and much more for only $99.95 either system.

DOSPlus v3.3

Micro-Systems Software

dsp3v33a.zip

MODEL III FOR $175.00 Yes, double density is here! Two 40 track drives give you 368K of storage. And if thats not enough, four 80 track drives will give you 1.4 megabytes of on line storage. All this with the added speed of double density operation, not to mention 80% more storage per diskette. No loss of your software library or conversion of your single density diskettes is necessary. DOSPLUS 3.3D reacts to the diskette. It will read single or double density with equal ease. It is not JUST a double density operating system, it is a double AND single density system. It is the first of it's kind. No one can offer you what we can! To change a disk to double density you need only format a double density disk, and then ONE command (TRANSFER), will bring over all your files. Very simple to use, but not necessary, because DOSPLUS will read them as they are now. Just insert single density diskettes and run (with our operating system). The machine will know what you are doing without having to be told ANYTHING! If you want your computer to chain functions, then you need DOSPLUS 3.3D (for example, from powerup you could have your machine call another computer, scan a data base for appointments, recording any that appear on your printer; and then load in our new BASIC, setting files and mem/size, and start your program so your secretary can go right to work). With our BUILD, DO and AUTO, all of the preceding would be child's play. By the way, you could have also set the time and date, looked at the directory of all your drives as well as checked the free space map (which tells you not only how much space you have on a diskette, but also where it is and what it is used for) DOSPLUS is a truly intelligent, easy to use operating system that gives you all your computer is capable of delivering. You probably guessed that for $175.00 what we are doing is turning your Model I into a Model III. It's so easy anyone can do it in 10 minutes! Why spend $2,500.00 for a Model III when you can get the same computing power, with our kit, and NO SOFTWARE CONVERSION, for only $175.00. Don't throw away your Model I, let us expand it! Move up to the world of double density. You will reap the benefits of our error-free software. No miracles, just plain hard work and a lot of testing by experts and novices alike. Test us and judge yourself. We guarantee you will be 100% satisfied. If you are the first to find a legitimate 'BUG' in our software you will be rewarded with a brand new $100 dollar bill. Your systems disk will come complete with an all new single/double density disk editor called DISK2AP, and a BASIC program compressor called CRUNCH. Also included is PURGE, a utility to make the mass removal of unwanted files from a diskette easy, and RESTORE, a program that makes recovering a dead file as easy as typing in a command line. TRANSFER is just as it sounds, a program that moves all files (except systems) from one diskette to another. Single density to double or vice versa. CLEARANCE is used to zero data files on a diskette for a 'clean slate'. DISKDUMP is a new machine language sector display/modify program that works with filespecs instead of tracks and sectors. Used in conjunction with DISK2AP, you will have more disk editing power than ever before, with less frustration than was ever thought possible. You will now be able to use all your DOS commands from our new BASIC with the CMD feature. And how about variable length records that really work, first time, EVERY time! This will allow you to use the ISAM programming technique for vastly improved handling of large data bases and lightning speed unheard of in BASIC. (ISAM stands for Indexed Sequential Access Method). You can create programs that will run on MOD III DOSPLUS, yes, 100% compatibility. If inflated computing power without an inflated price tag is what you're after, contact us at the address below.

Move up to the world of double density. You will reap the benefits of our error-free software. No miracles, just plain hard work and a lot of testing by experts and novices alike. Test us and judge yourself. We guarantee you will be 100% satisfied. If you are the first to find a legitimate 'BUG' in our software you will be rewarded with a brand new $100 dollar bill. Your systems disk will come complete with an all new single/double density disk editor called DISK2AP, and a BASIC program compressor called CRUNCH. Also included is PURGE, a utility to make the mass removal of unwanted files from a diskette easy, and RESTORE, a program that makes recovering a dead file as easy as typing in a command line. TRANSFER is just as it sounds, a program that moves all files (except systems) from one diskette to another. Single density to double or vice versa. CLEARANCE is used to zero data files on a diskette for a 'clean slate'. DISKDUMP is a new machine language sector display/modify program that works with filespecs instead of tracks and sectors. Used in conjunction with DISK2AP, you will have more disk editing power than ever before, with less frustration than was ever thought possible. You will now be able to use all your DOS commands from our new BASIC with the CMD feature. And how about variable length records that really work, first time, EVERY time! This will allow you to use the ISAM programming technique for vastly improved handling of large data bases and lightning speed unheard of in BASIC. (ISAM stands for Indexed Sequential Access Method). You can create programs that will run on MOD III DOSPLUS, yes, 100% compatibility. If inflated computing power without an inflated price tag is what you're after, contact us at the address below.

DOSPlus v3.3.1

Micro-Systems Software

dsp3v331.zip

MODEL III FOR $175.00 Yes, double density is here! Two 40 track drives give you 368K of storage. And if thats not enough, four 80 track drives will give you 1.4 megabytes of on line storage. All this with the added speed of double density operation, not to mention 80% more storage per diskette. No loss of your software library or conversion of your single density diskettes is necessary. DOSPLUS 3.3D reacts to the diskette. It will read single or double density with equal ease. It is not JUST a double density operating system, it is a double AND single density system. It is the first of it's kind. No one can offer you what we can! To change a disk to double density you need only format a double density disk, and then ONE command (TRANSFER), will bring over all your files. Very simple to use, but not necessary, because DOSPLUS will read them as they are now. Just insert single density diskettes and run (with our operating system). The machine will know what you are doing without having to be told ANYTHING! If you want your computer to chain functions, then you need DOSPLUS 3.3D (for example, from powerup you could have your machine call another computer, scan a data base for appointments, recording any that appear on your printer; and then load in our new BASIC, setting files and mem/size, and start your program so your secretary can go right to work). With our BUILD, DO and AUTO, all of the preceding would be child's play. By the way, you could have also set the time and date, looked at the directory of all your drives as well as checked the free space map (which tells you not only how much space you have on a diskette, but also where it is and what it is used for) DOSPLUS is a truly intelligent, easy to use operating system that gives you all your computer is capable of delivering.

Circle 91 on Reader Service card. These were printed by DOTWRITER on an Epson MX-80. See What You Can Do With DOTWRITER 4.0! Now available for the Model 4, too! DOTWRITER lets you create spectacular, eye-catching letterheads, catalogs, invitations, or even books. It is just what you need to turn your dot-matrix printer into a versatile typesetting machine. And it's available for the Model 4 (yes, in native mode) as well as for the Models I and III. What is DOTWRITER? DOTWRITER uses the 'bit-image graphics' of your printer to produce the kinds of stunning results shown inside the box. It is a full-function text printing program, so you can inter-mix different character sets, do centering, paragraphs, pagination, magnification, draw horizontal and vertical lines, reversals (white on black), and even print right-justified proportional text. DOTWRITER includes the printing program, complete documentation, and fourteen useful sets of typefaces (60 to 90 characters in each set). We will include the 160 page Letterset Reference Summary at half-price ($10.00) with your order. To use DOTWRITER, just write your text with any popular TRS-80 Word Processor, add the necessary format- ting commands, and DOTWRITER will do the rest. 35 more disks are available separately. Each has 3-12 complete typefaces (60-95 characters in each set). These disks cost less than $25 each, and may be purchased at any time. If you want to create your own logos, modify our typefaces, or even design entirely new typefaces, then you will also want to order the 'Letterset Design System' (LDS). We offer LDS at half-price when you order it along with DOTWRITER. LDS operates in Model III mode on the Model 4. Versions are available for Epson MX-80 with Graftrax, MX-100 with Graftrax-Plus, RX-80, FX-80, C. ITCH 8510/1550, Microline 64/92/93; Radio Shack's DMP series 200-2100, CGP-220 & Gemini 10X, 15X.

DOTS Utility PackageMISSING

MicroSmith Computer Technology

Connect the D.O.T.S. The D.O.T.S. utility package ($29.95) lets you create, edit, and print designs on a dot-matrix printer using the Model I or III. The programs, from MicroSmith Computer Technology (Box 1472, Elkhart, IN 46515, 219-293-8339) use an overlay that you put over the design you're digitizing. The enlarged grid on the overlay is proportional to the dot spacing on Epson and compatible printers. You can then modify any graphics block of 8 by 8 dots with the video graphics editor. D.O.T.S. creates a data file for use with the print routines and includes routines to print designs on labels or as a logo on standard printer paper. Two other Model I/III programs, Screen-It ($24.95) and Microcomm ($24.95), are available from MicroSmith. Screen-It saves print-out paper by letting you display Scripsit files as they will print out. The Microcomm communications program transfers CMD files, up- and downloads programs, and saves information to a buffer. It requires 48K RAM and a printer.

dbldtym3.zip

Amazing DoubleDuty Utility Makes Your Model 4 Work Like Two Computers! 6995 . Lists You Load Two Different Programs at Once . Move Back and Form Between Programs Without Reloading . All Information You Enter Remains Intact for Both Programs-Even While You Move Between Them . Retains All TRSDGS and BASIC Commands While in Use DoubleDuty. Divides your computer's 128K memory into three complete and independent partitions. Partition 1 and 2 each operate like a 64K Model 4. You can load and execute any Model 4 program designed to run on a 64K system into each partition. You can also run BASIC or TRSDGS commands in either partition. In addition, you can use Partition 3 to execute TRSDGS library commands. It's like having two separate Model 4 or Since most Model 4 programs require no more than 64K, DoubleDuty takes advantage of your system's increased memory capacity. And because DoubleDuty takes up almost no memory itself, it is able to more than double the system's operating potential. For example, you could load the SCRIPSTY word processing program in Partition 1, and an electronic filing program in Partition 2. While typing a document in SCRIPSTY, you discover that you need data stored in the file program-you simply move to the file program, find the information, and return to SCRIPST. You may reference the TRSDGS directory for information-all without disturbing your document. Designed to use your full memory capacity for convenience and speed. Requires 128K Model 4 or a Model 5S modified with Model 4 Upgrade Kit (26-1123) and the Model 4 64K RAM Kit (26-1122). DoubleDuty may not be compatible with all Model 4 programs. Communications may not be used with DoubleDuty. 26-223'. 69.95

DOUBLE-ZAP II - DOUBLE DENSITY PATCH FOR NEWDOS 80 ONLY $53.00 plus $1.00 p&p If you are using NEWDOS 80, then you also need DOUBLE-ZAP II, on diskette. This program upgrades your NEWDOS 80 to double density with ADR (automatic density recognition.) It retains all the familiar features, including the ability to mix and match track counts on the same cable. In addition, it gives NEWDOS 80 the ability to mix densities on the same cable, automatically. If you place a single density diskette in drive , say and a double density diskette in drive 1, Double-ZapII will recognise this and read/write to drive in single density whilst at the same time it reads/writes to drive 1 in double density! ---

DoubleCross FileFix and FreeForm [Montes Toolkit]

Montezuma Micro

M8 · 1985 · COM

dblcrsmt.zip

MONTEZUMA MICRO WOW! ANOTHER NEW PRODUCT FROM MONTE PRESENTS MONTE'S TOOLKIT $49 REQUIRES: Montezuma Micro CP/M 2.2 version 2.21+ Monte's Toolkit is a collection of utilities that will prove useful to every owner of Montezuma Micro CP/M (you all are owners, aren't you?). It's a disk full of programs that perform functions that are difficult, cumbersome or expensive to do any other way. Monte has tried, in his own way, to briefly explain each function for you below. Read on and be saved. DOUBLECROSS allows unlimited file transfers between CP/M, IBM-DOS and Model 3/4 LDOS /TRSDOS with unsurpassed ease and speed. In fact, you can move just about anything from any disk to any other disk but you might have to make changes for program operation. Lotus 123 just flat won't run on your Model 3 and I doubt that you could ever modify Scripsit enough to run on the IBM. Simple menus guide you through the operation with minimal keystrokes. Just tag the files you want in the directory display and go. You won't get doublecrossed with DBLCROSS. FREEFORM formats and backs up Model 3/4 LDOS/TRSDOS and IBM MS & PC- DOS (versions 1.x, 2.x and 3.x), both single side and double side plus there is a special 'clone' copy when you just don't know or care what you have. Just insert a disk and copy away. All you have to know about the disk is how to get it into the drive. The Analysis feature lets you look at and print the actual structure of a disk - even the ones with 'funny' formats. WSPR lets you print to almost any printer using almost any control code. It's nearly magic and does a whole lot more than I can talk about here including letting you print anything your printer can print. FILEFIX gives you the ability to 'fix' your 'files' by adding line-feeds when your files are going from CP/M or IBM-DOS to LDOS/TRSDOS or take them away if you are transferring the other way. You can remove the control codes from a WordStar document thereby converting it to a non-document file. The fix will also fix up Scripsit files so they can be used by CP/M and IBM-DOS based wordprocessors (you know - the real ones). All this is accomplished with the use of simple menus and boy, it is fast. SYS2M requires 128K and our CP/M. The CCP and the BDOS are moved to drive M and the BIOS is modified to allow a Warm Boot from Drive M. So what you say. Well, you still have to have a disk in drive A but it no longer has to have the CP/M system resident. It can be anything. This little jewel copies frequently used programs to drive M and searches there first for all program requests resulting in much faster program loading. Slick isn't it? AUTO is a little goodie that lets you issue multiple commands from the command line. Eliminates the pain of Submit. As in all the other parts of MONTE'S TOOLBOX, complete and comprehensive instructions are included and it's available right now.
