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

The Disassembler This is a single-pass, hex-notation disassembler that will send its output either to tape or to a lineprinter (Radio Shack parallel port). The tape output is directly compatible with Tandy's ED-TASM. Thus, you can take an object code tape, disassemble and output it to tape, then use EDTASM to add, delete, change and even re-assemble your new version. In addition, it displays the displacement and absolute address of any relative jumps made by the disassembled program. It also displays any ASCII characters used in a LD or CP opcode. Sample output from the Disassembler BYTE MACHINE LINE MNEMONIC COMMENTS --- --- --- --- --- NUM. CODE NUM. COLUMN 706E 22057B 00053 LD (7B05H),HL 7071 183B 00054 JR $ + 3DH ;70AEH 7073 FE52 00055 CP 52H ; = 'R' 7075 2007 00056 JR NZ,$ + 09H ;707EH 7077 CD8F70 00057 CALL 708FH H means the number is HEX $ means current location counter. Since the Disassembler works only on in-memory programs, it has been made relocatable so that you may move it around in memory to avoid conflict with the program you wish to disassemble. As an added option, you may also jump to memory locations and transfer control between Disassembler and other utility programs in your computer.

## A REVIEW OF Z-CHESS III from England
 
Z-CHESS III - NOW THE BEST
by A. J. Harding (Molimex)
 
It is particularly appropriate that a new star should show in the heavens at Christmas time, so it was with great interest that we received our master copy of the new version of Z-Chess from Adventure International. For some time now it has been conceded that from a skill of play viewpoint, Sargon II has been the leader in the various chess games available for the TRS-80. As it is close to a year ago since we had a tournament here to try and obtain information on how the various games were played to pass on to our customers, we thought that this would be a good time to have another one. We therefore staged a game between TRS-80's, one running Z-Chess III and one running Sargon II. As both programs have seven levels of play it would presumably be fair to play at any level, but for reasons of speed, we decided to play them against each other at their lowest levels. Without any hesitation, we award Z-Chess III the Molimex Cup. Not only did it beat Sargon II but it did so playing from a black position. In other words, the game was started with Sargon II waving the first move as white, which of course gives that player an advantage. Despite this, Z-Chess III played a better game and won. We allowed the game to go 73 moves even though it was quite obvious towards the end that Z-Chess III was going to win. In the end Z-Chess III, as we have said, playing black, finished up with one pawn, one bishop and a queen to Sargon's single king. As we were playing the two programs against each other at their lowest levels, speed did not really become a factor. Sargon II was slightly faster, but Z-Chess III certainly played within its ten second limit for a move. When Z-Chess was first introduced we had a feeling that it would become a champion and human nature being what it is we are extremely pleased that our hunch has proved to be true. We have no hesitation, therefore, in recommending Z-Chess III especially as it is only about two-thirds of the cost of Sargon II. Z-Chess III is available on cassette for 16K machines and on disk for a minimum of 32K.

AUTOMATIC DENSITY RECOGNITION for Newdos/80 Version 2.0 The evolving line of Apparat operating systems has constantly met with customer approval. However, with the advent of double density, many N/80 V2.0 owners were chagrined by the lack of Automatic Density Recognition -- the capability to recognize both single and double density diskettes. Both can be online at the same time, but we have to reconfigure the PDRIVE parameters as we change density. That is no longer a problem. Headaches gone! DDSD/CMD was designed by Allan J. Domuret, noted author for many popular computer magazines. DDSD is no more complicated than just executing it from DOS READY. No disk ZAPS of any kind are required. DDSD can even be an 'AUTO' file. This program functions with all TRS-80 DOS systems and will not adversely affect fast CPU clock systems. DDSD will load itself at top of available memory, respecting any and all programs present. DDSD is compatible with both Mods I and III. DDSD is available only on cassette, but will easily convert to a disk file by use of LMOFFSET, a utility available to any NEWDOS owner. The general availability of this utility is exciting news for all N/80 V2 persons!! Even more exciting is the price: $19.95, less than half the price of similar utilities. And that's not all For a limited time, DDSD can be yours for just $10 -- if you subscribe to TAS at the same time. Twelve issues are $24. DDSD is $10. For maximum value, our special FLY offer is still available ($45 for 24 issues, FLY is free). There is no better time to check out this journal, so do it now! TAS focuses exclusively on the Mods I and III. DDSD/CMD, alone, is $19.95 plus shipping.

ZAPSIT 1981 by Soft Sector Marketing, Inc. - Written for TRS-DOS & DOSPLUS by Larry Ashmun Requires 32K Disk - Mod III Zapsit is a stand alone machine language program that lets you examine, modify, copy disk sectors and much more. It does not use any of the resident DOS routines so that you are not limited to the restrictions of the particular DOS that you normally use. You do not have to have a system disk in DRIVE 0 once Zapsit is running. Currently there are two versions of Zapsit - one for use with TRSDOS and one for use with DOSPLUS. They are the same except in the way that they format a disk and the way that they write DATA ADDRESS MARKS. Because of the differences, they are not interchangeable. Writing to a TRSDOS diskette with the DOSPLUS version (or vice-versa) could make the diskette written too unuseable. For all disk operations you will be asked a series of questions. Each question can be answered by pressing the ENTER Key or by entering a specific value. Pressing the ENTER Key will cause the DEFAULT value to be used. All default values are indicated on the screen at the time the question is asked. When entering a specific numeric value it is assumed to be DECIMAL unless an H is appended to the number. When an H is appended, the number is assumed to be hexadecimal (base 16). CAPABILITIES Display/Modify Disk Sectors/Memory. Print to screen. Print sector to printer. Modify in Hex. Modify in ASCII. Change Track & Sector Limits. Single density read and write. Double density read and write for 1-80 track, from 0-18 sectors. Single and dual sided drives. Format a Disk. S = Standard Format. W = Format without Erase. If you press ENTER or S you will be asked which drive, what density. After answering these questions Zapsit will format the disk using the parameters specified. As each track is formatted all of the sectors are checked for readability before the next track is formatted. Any unreadable sectors are reported but the operation will not be aborted. If you type W you will be asked which drive, what density to use and if you want any bad sectors reported to the printer. Before each track is formatted each readable sector on the track is read into a holding area. Unreadable sectors are reported and their holding area is zeroed. After all of the sectors for a track are stored, the track is reformatted and the data in the holding areas written to the appropriate sectors. Verify a Disk. Verify a disk does just that. It verifies that every sector is readable. Any unreadable sectors are reported. You will be asked if you want the unreadable sectors reported to the printer. Now you can verify that the format of your diskette is in good shape before you copy your important files to a diskette. This prevents losing your data that you are trying to back up. Copy Disk Sectors. Copy disk sectors allows you to. Copy sectors (Single or Double Density) from a disk to different sectors on the same disk. Copy sectors from a Double Density disk to a different Double Density disk. Copy sectors from a Single Density disk to a different Single Density disk. Copy sectors from a Single Density disk to a Double Density disk. Copy sectors from a Double Density disk to a Single Density disk. All copying to a Different disk must be done on a Two Drive System. Zero Disk Sectors. Zero disk sectors allow you to write a value of your choice to the sectors specified. Read a Track. Reading a track allows you to read an entire track into memory, with all of the address marks and information that you don't normally see with a sector read. The output can be to either the screen or printer.
