  1. Originally sold by Elek-Tek too. They supported TI products pretty heavily from the beginning up until 1986 or so. I'm not sure that the Applications Programs brochure is archived anywhere either. . .
  2. The TI followed several conventions for disk use. Disk management was accomplished with a disk manager program. TI produced cartridges with the disk manager software on them, but there were also generic and hardware specific (read: tuned to specific third-party hardware) disk managers as well. BASIC could load applications using "OLD DSKx.yyyyyyyyyy" where x was the disk number (between 1-3 for some controllers, and 1-4 for others) and yyyyyyyyyy was the filename (note, the TI file system is case sensitive). You could also load from a specific "Disk" by specifying the disk's header name: "OLD DSK.xxxxxxxxxx.yyyyyyyyyy" where xxxxxxxxxx is the disk name and yyyyyyyyyy is the file name on the disk. Lastly, when using Extended BASIC, the system would check DSK1 for a program named "LOAD" when starting BASIC. If the program was there, it would autoload it and execute the program without any required action on the part of the user. I hope this helps. . .
  3. The cartridges built and sold during and shortly after the withdrawal of TI from the Home Computer market should all work on the FinalGROM99. This is because it has both the ROM and the GROM parts of the cartridges stored in its memory. The problems will be with the majority of the homebrew cartridges produced after the year 2000 or so (there are a few earlier ones as well, but most of the problems show up with cartridges written after that date). Most of these homebrew cartridges were designed to use the cartridge memory as a temporary storage area. When you launch the cartridge, it copies the data from the cartridge into your 32K memory space (and there are even a couple that require SAMS memory instead, up to 1M). The program then runs from the regular 32K memory space--not from the cartridge. Pretty much anything created with a compiler follows this model, as do most of the games written and posted here on AtariAge. There are exceptions: any game written by @sometimes99erwill run fine from your FinalGROM99, as they are designed to run out of cartridge space, as are Turmoil by @PeteE and Pitfall! by @retroclouds. As to modern utilities that also run out of the cartridge space: RXB2020 by @RXB, Explorer 1.1 by @FALCOR4, TurboForth by @Willsy, and FBForth by @Lee Stewart
  4. B. R. S. would most likely be Bill R. Sullivan. . .so you would have seen that in some Forth+ documentation, @GDMike
  5. He's still in Berlin, last I knew. He showed up to one of the European Treffs a few years ago, IIRC.
  6. Yes, Restless III would be something refreshing to play, like all of your games, @sometimes99er
  7. I play this game pretty regularly, as it is a lot of fun.
  8. Funny thing here. I was doing some parts hunting a couple of weeks ago and found someone selling a TMS5100 and a TMS5200. I bought both of them, as the prices were not too egregious. The same seller also had a few TMX9918 chips and a few TMS9903s. I bought some of the TMX9918s and the TMS9903s. Definitely an interesting source for odd chips. . .
  9. One note--the comments were cut off at the 80-column point on the original printout, so no further recovery of the ends of those lines is possible without access to the original files in TI-990 format (which we don't have). My copy was rescued from a dumpster at Almelo, Holland when TI cleared out their 99/4A lab there. A Dutch TI user saw something he recognized on his way out of the facility on the day they filled the dumpster, so he stopped to take a look. He filled the entire back of his station wagon with everything he could fit into it and took it home. Unfortunately, when he got back the next morning, the dumpster had already been emptied, so most of the stuff from that lab was lost forever (his car was only big enough to rescue a small fraction of what was in the dumpster in the first place, but it was good that he was at the right place and time to rescue as much as he did).
  10. Some of the nice, strange aliens from TI Invaders would be great, if they aren't all in there yet. A lot of those were pretty unique. The ships from Rasmus' TiTanium would also be a good fit. . .I haven't seen all of the levels, so a lot of them may already been used here. Do we have a list of the ones that have been used, or is that a delicious secret knowledge?
  11. These screws work so well with the Guidry cartridge cases that I bought a few thousand of them to ensure I had a permanent stock of them on-hand. . .
  12. It needs a total of 16 chips (assuming your current two chips are 128K, as I haven't looked closely at the part number on them). I usually use the following Alliance chip, although most any chip that is both fast enough and tolerant of the lower voltage when the card switches to battery will do. The price on these has slowly been going up again (even before the pandemic).
  13. Memory chips for that one shouldn't be a real problem now--and it has the socket for a second 154 already, so you can easily double-stack it if you wanted to go that route with 128K chips (not so relevant if using 512K chips though). . .and a couple of the mods @FALCOR4 and I did to make the 4000B boards super stable could probably be done there too with a little cutting and a few flying wires.
  14. I will have to look in my files, as the text copy of that file that @urbite and I were using as our working file was on a hard disk that crashed right before a scheduled backup (and the file wasn't part of the previous backup of that disk). @urbite verified that his half of the code still assembled properly, as that was one of the tests we were doing as we reconstructed the file from the original code printouts I have in my collection. Some lines were longer than 80 columns, and were thus cut off at the edge of the page. Not so much of a problem with the comments, but a definite issue with the more lengthy lines of code (usually DATA statements). We went back to the assembled columns at the beginning of each line to properly reconstruct those when we found the issue.
  15. Anybody capable of driving this game over 100,000 points is orders of magnitude better than I am. I don't think I've ever gotten over 10,000 points in this game, and I think I only ever broke that number once. . .

    Eye Candy

    Do note, the version of Press Asgard released into the wild was not a complete version of the program, and even the parts that were included were a bit buggy. Charles Earl was trying to extend the overlay methods he used in his other programs to allow Press to be a truly capable program much larger than the regular TI memory space. Apparently, it was also a bit more difficult to do than he thought it would be--and so he stopped working on it before it was finished. There are probably 30-50 copies of it in the wild, released by Asgard when it became obvious that the program would never be finished. The original concept probably would have worked really well on a SAMS card, but only the executables ever made it out--the source code isn't out there anywhere so far as I know.
  17. Interestingly enough, that article was also the only hit I found for the chipset, using several different sets of search terms. . .
  18. I think I made it to More Bricks once--but I'm also sure it was a pure luck moment, as I am generally terrible at games no matter what the helpful tools I am using are.
  19. There were several E-Bus cards made for the Cortex as well: I know of a memory card, a serial/parallel card, a serial card with additional joystick ports, and an MFM Hard Disk Controller card.
  20. Definitely set up some kind of a hood with an exhaust fan to the outside. . .poisonings are bad things.
  21. As to archival storage, your best bet is to use an M-Disk. It looks like a CD/DVD, but it uses a completely different substrate for the data (and any recent CD/DVD writable drive supports them). The disks will hold the data for at least 100 years, and are reputed to last for up to 1,000 years without data loss. The disks are a bit expensive, but worth it for data you are interested in preserving for time periods longer than the recording format is likely to last. . .
  22. If you were going to use any type of metal case there, definitely stay away from the TI cases, as they have some metal bumps inside at dangerous points for shorting out boards. A CorComp, Atronic, or Foundation case would be much less risky--but you would still have two issues: the spacer/standoff issue (those cases come with them already though) and the exit point from the case for the back of the PEB (tape may be enough to solve this last issue), but it is still a bit iffy, as the card really wasn't designed to go into a metal case.
  23. Several TI carts used the blobs. Miner 2049er, Espial, St. Nick, and even some experimental The Attack cartridges from TI.
  24. Nice bit of background data exchange on how GROM bases work too. It is unfortunate that the actual (original) Arcturus cartridges are so hard to find. I like the cartridge shells they used--and those cases could be used with somewhat different circuit cards as regular cartridge slot cases as well, so they were nicely multifunctional. I may have to open mine one of these days and see if I can make a mold set for the cases. . .and the Killer Caterpillar cartridges in the same shells are even harder to find.
  25. These should work fine on any non-inverting board (Red, Yellow, or UberGROM) without any issues. If you want to use them on one of the inverting boards (Guidry or Black boards), you'd have to run them through a bank inverter program first (Rasmus put one up that will switch bank order back and forth between the two types a long time ago).
