  1. This looks like a later variant of the original RAM Trap tester from TI. I recently acquired one of the TI-Style testers, but I haven't taken time to try and read out the ROM yet. One note: the TI variant has two switches, while the one in your schematic only has one, so the software may not be fully compatible. . .and no, I don't think I've ever seen the EPROM for this one in the wild, although @atrax27407 may be able to find it in his EPROM reference library.
  2. Looking at the schematic @HOME AUTOMATION linked to, this is for the QI board (at least that's what the note on the bottom of the schematic says).
  3. I have even made a few cartridges of the first two versions--I just need to extend the label to make a ROD3 version. . .and then maybe I should just make a cartridge with all three in it. We could call it the ROD experience, LOLOL
  4. It is actually to figure out which of the two console ROM chips is for the even bytes on a QI console so that a modified chip will land in the correct socket. . .
  5. The disk releases came after the cartridges and were intended to attract people with disk systems to the games, as the disks were a little less costly than the cartridges. It gave folks an option. None of the disk versions were well-marketed, so sales stayed abysmally low for all of them. TI then quietly dropped them and doubled down on the more profitable cartridge releases. . .
  6. Munchman and TI Invaders were the other two disk releases of games usually only found on cartridge.
  7. Oddly enough, I was looking at my Tombstone City disk this past weekend. . .and it is the standalone version too. I'll pull it out again and check, now that I know where it is again.
  8. It has a hypertext program as well: HQ Stacks from McCann Software.
  9. Bonus, progress ensues. I'm glad to see this one move forward again.
  10. It is also possible that they considered this option at about the same time they were releasing Tombstonce City, TI Invaders, and Munchman on disk--and then settled on Tombstone City as the only one they were truly willing to release in source code form.
  11. @humeur here on the forum is also very familiar with the Exelvision machines. Between him and @fabrice montupet, pretty much any Exelvision questions can be easily answered.
  12. Actually, I have a Lotharek connected to an HFDC modified to work as a floppy-only controller in a TI. It too fails to write--although it reads fine. I thought the issue might have been a cabling issue that I haven't had time to look at as write wasn't super-high on my needs list, but your experiences tell me I might want to try a different controller just to see what happens there. Looks like I may need to dig out one of my spare controllers. . .
  13. I went digging. It appears that I indeed purchased two copies of Markus (both Limited Edition, with stickers to that effect on the bags), one black cassette and one red one. ISTR that you had limited numbers of the red and blue ones, but also offered black for those with multiple purchases. I also found both of my disk copies of W&W. Oh yes, and your message box says you can't receive messages. . .

    Eye Candy

    I have physical copies of all of the titles Infocom released for the TI, and in addition to that, I have physical copies of all of the titles Asgard released under Infocom license.
  15. I'll look on the Markus files, @Opry99er. ISTR that I bought two from you. . .
  16. And with a standard floppy drive, the changes you made to the names will allow the correct files to load, so you were on the right path for use with a floppy drive. The tips from @9640News will be invaluable once you change over to the V2.00 boot EPROM, as it replaces the slash from earlier versions of the EPROMs with a dash.
  17. It has the cable too, which fits all of the DBT cartridge port modules with print capability.
  18. Harald Glaab can tell you a lot about this one. I believe there was also an extensive article about it in the German TI-Revue magazine.
  19. It might not be a bad idea to run the cable daisy-chaining PEBs through a set of buffer chips to keep from overloading bus drivers--that may have timing consequences, however.
  20. Several of the 18-cartridge hinged-lid boxes have shown up on eBay in the last couple of weeks, but not alone. They were either part of a larger lot of random TI stuff or they were included with a group of cartridges. I've seen at least one of the plastic console shilds show up in the last few weeks as well.
  21. That being the case, you might also have issues with a Triton Super Extended BASIC cartridge. It likely won't affect the MicroPal or Exceltek versions of Extended BASIC, as they both use pretty much the same circuitry TI did.
  22. Did this change the symptoms for the items that didn't work after the original mod?
  23. Not quite true. The function of the GROM Buster is to hijack the console startup routine when it checks the >4000 space. It then executes a routine that scans the cartridge port and puts the appropriate entry for the ROM cartridge into the selection menu. The cartridge must be in the cartridge port, as usual. The GROM Buster does pass the bus on through to additional peripherals, so it doesn't act as a bus terminator like the TigerVision, Exceltek, CorComp, or DataBioTics sideport cartridges. One would have to design another device to do what is being asked for here--and it would need to pull any missing signals out using wire connections to bypass the sideport. Even then, it would likely still need the necessary delay circuitry to eliminate the known timing difference of the QI consoles.
