  1. As printed in the book, the line does not have an error.
  2. What good would a document be as a BASIC program?
  3. I think of all the TI cartridge manuals I've encountered, only the Mini Memory manual stated that the console should be powered off before inserting or removing the cartridge. All of the others tell you to turn on the console prior to inserting the cartridge
  4. It's been ages since I've played the the MAME emulation of the 99/8; does MAME emulate memory expansion for the 99/8? As an aside, I actually had a 99/8 for a while many years ago. Mine had the p-system intact, but there was no card edge connector for the expansion bus on the side (just bare board), so I could only use cassette with it. I sold it when I had to, but I hated to do that and I wish I still had it. It was definitely faster than the 99/4A, and TI Extended BASIC II was more full featured, but it definitely suffered from not having a better video and/or sound chip.
  5. The 99/8 kind of addressed it right? It had CPU RAM separate from VDP RAM. TI Extended BASIC II had access to machine language. I'm not sure sticking with the 9918 (9118) was the best choice when they could have gone with a better VDP by then.
  6. Wheel of Fortune on the C-64 is very interesting because it's written in BASIC! It does call some machine language routines, but the game engine is BASIC. I found this out when I loaded a directory and then loaded one of the programs and realized it was the game. That did allow me to fix a screen formatting error that had bugged me since I had this game originally BITD.
  7. Forgive an ignorant question from a non-Apple II guy (though I have used them of course). What was different in BASIC between ProDOS versions? I thought Applesoft ran from ROM, and I know that DOS intercepts the input/output to look for DOS commands with the CHR$(4) notation. Is it just that part of BASIC that changed?
  8. Robin at 8-bit Show and Tell on YouTube has a video describing something similar - it might be the case for you also. In his case, the head bumped too far and got stuck and he was able to "free" it. Perhaps this is what happened to yours as well.
  9. I had several Tandy 1000s back in the day. Thanks to Radio Shack putting the next more powerful model on sale within the 30 day return period, I went from a 1000 RL to 1000 RLX to 1000 RSX in about 3 months and actually got money back doing that. While I can't speak for all Tandy's, none of those were at all bad. I then had a Tandy 486 (Tandy 2100 Model 10 I believe) when I was in college and my friend who had a custom built 486 bought some RAM for his computer that he was sure was defective since it didn't work, yet worked just fine in my Tandy, so they weren't all bad. The worst computer I ever bought was a Philips Velo 1 Windows CE device. It was cool and I *really* wanted it when I bought it, but I couldn't use it for anything at all.
  10. Actually all of the "answers" to the error message work at any prompt. If you type in OLD CS1, and press R when it says "Rewind Cassette Tape" - it will say it again. You can press C and it will "check" instead of "read" even when that doesn't make sense to do. I'm not sure if it actually loads anything if you tell it to check though.
  11. Very interesting. The beige model in the last image is like the one I got when TI was getting rid of them here in the USA. The box, however, is very different, and reminds me of the TI 99/4 box
  12. While I did not do it for 8 hours a day, my first job which I was still in high school was at the public library in my town. At that time, the library had an Apple IIe for patrons to use, but the library's circulation database was managed by an IBM PC XT with the green phosphor monochrome monitor. Transaction backups were written to floppy disk every 30 or so transactions. At some point we got a new version of the database application and it just could not run well on the XT. The interactive part was ok, but when it would do the transaction backup to floppy disk, that would take up to 20 minutes instead of the 30 seconds from the previous version. The XT was then replaced with an IBM PS/2 386 (with monochrome VGA monitor) and the XT was relegated to the back office where it was used to create card catalog cards, book spine labels, and it would write those records onto a floppy disk that we could take over to the PS/2 to import into the database. Since the machines were not networked (no network at all in the library), this was how we interchanged information between them. Years later, I was given that PC XT... I wish I still had it.
  13. Just to add to what others have said: TI BASIC (And Extended BASIC) have commands built in for loading and saving programs and manipulating files (OPEN, DELETE, PRINT#, INPUT#, etc). None of these commands are device specific, but the file name portion of the command indicates which device it is to be sent to (similar to a device number for the Commodore). Where Commodore machines send commands to the disk drive to do things like format, copy, etc - TI uses a cartridge to do those things. Disk Manager (and Disk Manager 2) were the official TI cartridges, but as mentioned, other vendors produced their own that worked with their hardware. When you bought a disk drive for a TI, you needed to purchases a disk controller if you didn't have one (either a standalone peripheral device or a card for the PEB). The disk controller included the Disk Manager (or Disk Manager 2) cartridge as part of the package. I assume that would be the same with the non-TI controllers.
  14. Others I can think of: TP SPEECH ALPHON MINIMEM EXPMEM2
