In response to Howard Benner's request, I'll tell you what I know about Tandy 1000 program compatibility (and some other stuff)... First a general statement -- some large programs will require more memory on your T-1000 than on a PC. Reasons are we use 16K of RAM for video (same as PC Jr), where the PC has separate dedicated RAM. And, BASIC on the T-1000 is loaded into RAM, where on the PC, part of it is in ROM. The difference, I hear, is about 48K. ------------------------------------------------------------------------------- Programs we know will NOT run (please EMAIL us if you find others): "Math Blaster" - Davidson & Associates "MasterType" - Scarborough Software (late report - "MasterTypeII" runs) "Alphabet Zoo"(IBM Version) - Spinnaker "Murder by the Dozen" - CBS Software ------------------------------------------------------------------------------- Caveats you should be aware of: 1. Some large programs will require more memory on the T-1000 than on the PC. 2. It's possible a few will require DMA (included in first memory upgrade). 3. IBM's keyboard is different, so there will be some adjustments to make... for example, in Microsoft's "Flight Simulator", you can't use our separate arrow keys. You'll have to use the numeric keypad keys where the arrows are on the PC. Another is IBM's [SCROLL LOCK]... on the T-1000, you use [CTRL][BREAK]. I'm sure there will be some other differences, but don't know them personally. Can anyone add any for me? 4. On some T-1000's shipped prior to 12/15, some IBM software wouldn't print on a Tandy printer. It was a bug in the hardware that's been fixed. If you have one of these early models, and experience the problem, return the 1000 for a modification. If it ain't broke, don't fix it! 5. On the off chance that a program is written in BASIC, and you "acquire" a copy on a disk with PC-DOS, you can boot, but not run it. Remember, part of IBM's BASIC is in ROM! 6. It's possible that a BASIC program might generate FC or Syntax errors on a T-1000. The preliminary version of BASIC does have a few incompatibilities (don't know exactly what), but a new release expected in March will be more compatible and faster. NOTE: this is a POTENTIAL "gotcha", but I haven't heard any complaints yet. ------------------------------------------------------------------------------- What will be different about "Tandy versions" of software for the Tandy 1000? 1. Manuals will be specific to your machine, and keyboard. 2. Some, like "Flight Simulator" will take advantage of the T-1000's enhanced graphics and/or sound. 3. Our versions of printing programs will support Tandy peripherals, use our printer codes, etc. If you have a non-Tandy printer, buy the IBM package. Of course our LATEST printers have switchable modes... Tandy or IBM. Why didn't we make those programs support IBM instead of Tandy add-ons? Because a LOT of upgrading Tandy owners will own older Tandy peripherals. We don't want them to have to buy a new printer to be able to upgrade. Remember 1) IBM versions of the program are available in the open market for those who need them. 2) New Tandy printers will be mode selectable, to run with either. Right now, those printers that have switchable modes are the DMP-2100P and the DMP-430. PRINTER WARNING: An Okidata "Microline 80" will damage your T-1000 if attached, due to high voltage on one of the printer's pins. Either your printer or T-1000 can be modified to eliminate the problem, without affecting the printer's operation with another computer. Serial printer support will be possible via the MODE command, which will be implemented in MS-DOS 2.11.01, available late Feb/early Mar. ------------------------------------------------------------------------------- Requests: 1. If you know of other programs which won't run, EMAIL info to either... David Frager, T-1000 guru, 70007,502 or Ed Juge, 70007,1365 2. If you bought an EARLY T-1000, and didn't get a software registration card, see your store NOW. Have them send your name in and get you registered. There are new versions of DeskMate, MS-DOS, and BASIC avaialble/coming. If you aren't registered, you won't be notified. OLD NEWS: Your registration card has N-O-T-H-I-N-G to do with warranty. Your warranty is based on the date on your sales ticket, and nothing else. So if you haven't sent it in, intending to "extend" your warranty, send it! That card and 50 cents will get you a cup of coffee at your neighborhood repair center... NOTHING else. So, obviously, HANG ONTO THAT SALES TICKET! ...Ed Juge, Tandy
