  1. Looks like you have improved the silk screen? Some TI boards were problematic about having the silk screen between solder pads (where you typically need them the most...).
  2. dhe


    Does anyone have two old Myarc PEB card cases the would sell?
  3. I think the gold standard might be Tech Drive by Monte Schmidt. If you have the cyc there is a clean copy on it.
  4. I powered up my TI system with SCSI Controller and Syquest Drives. My DM2K say (c) 2003. I think it is time for an update.
  5. Tim, Looking at your boot screen, you and RickyD have the exact same symptoms - One or more Character(s) corrupted identically.
  6. Missed your chance of becoming a member of the prestigious DOWNEAST 99ers? Well, here is your chance! 😃 I picked up their box of un-used membership cards about 20+ years ago, and am willing to mail you one unfilled out card to the address of your choice, I just asked they you mail back postage.
  7. From the coloring, I suspect it's Michael Becker's 32K on the 16 bit bus board.
  8. Jim might know the answer to your questions, I don't, I just purchased the Western Digital Drive, for all I know, Dee, might have formatted it before he sent it to me. I've also have not heard from Dee, in over twenty years. Not Geneve related, but I did get an email from Bruce Maret (also of Indiana, as was at one point Dee). Bruce is still around and probably has the foremost collection of faire video's any where - as he ended up filming most of them! 😃
  9. Maybe <- That's what we call a big maybe. Something to look forward to... McCann Software produced a number of leading edging packages for the Geneve. After McCann left the TI world, the rights to reproduce software was sold to Dee Turner. At some point, Dee also purchased Mac McCormick's WDS System, then later, I purchased it from Dee. At this point that WDS - in Unknown Condition has been sent to Jim for his touch. So maybe in the future, there might be more source and or packages come to light.
  10. Are TASM/TIC/Fortran on the list to go under the programming section? There was also the wonderful, but little used hyperstack by McCann?
  11. Good News, I'd gotten behind on updating, and I updated my version _31 to _38a, and SOB and Expanded Basic still work, so no recent enhancements have interfered with the special handling those two "special" pieces of hardware needed! ooraaa
  12. What's the current state of dskx emulation - where a directory on a hard drive emulates a floppy? I know at one point, it sometimes worked and sometimes didn't.
  13. We all owe a big thanks to Tursi for his tireless promotion of MAME! 😃
  14. I went through my binder labeled MDOS programming (contents of): GenProg Manual TASM Manual. Some notes from Genie An Email from Tim on how to compile MDOS (both floppy and H versions!) MDOS-IPC v1.0 A reminder to read the MDOS History File. A copy of the 9938 manual. Discussion of the hole in MDOS called External DSR Support 😃 Sadly, no notes from Beery, though I know I attended his MDOS programming class.
  15. There where a number of articles about it in the Chicago UG newsletter. I think one included a mod that would allow you to burn either 12 or 24 EPROM. I think that was also Atrex's go to burner, before he purchased one for the PC. For the most part, it's a pretty solid unit, just use the software that came with it and make sure your using the EPROM called for. Also, I've seen it once, but I think the folks at Inscebot created another program to burn EPROM's with a really kewl interface. I don't think it was every released as commercial software.
  16. I need to look at Fasterm source again, I remember someone mentioning at a Chicago Faire that Fasterm was almost built around the use of xops.
  17. >If there is something else you need, let me know. I'll look this coming weekend, and see if I have the notes you passed out when you taught intro to MDOS programming at the fairs.
  18. Tim, I think your Weekend update 2/14 and diagrams are very helpful. While most of us will never reach the guru status, there is the hope, some could serve the same purpose as the Linux janitors, and help document and clean up code. Putting the file names after the updates, very helpful. Beery, any chance you could republish your MDOS programming notes or are they out there and I just don't know where?
  19. Looking for one thing, lead me to this rabbit hole: These guys are hard core! 😃

    I'll hijack this thread for a dollar. The was some talk about an eprom upgrade for super sketch that would allow direct printing. Did that eprom ever emerge?
  21. In an effort to preserve my TI Equipment and make it run as error free and as long as possible, I purchased a UPS to sit the equipment behind. I'm getting ready to install a gotek drive, so I was think about some long deferred maintenance. In the past, I pull a card, put some ipa on a 4x5 index card and straight in and down in to the slots. Then a bit of ipa on a lint free qtip and clean the bottoms edge connectors of the cards from the pbox. Last step is to gently push down on an socketed chips. I think this time I would add a visual inspection of all voltage regulators. Once I get Jim extender card, I should probably add voltage readings to have a baseline. Anyone else picked up any good tips from other retro sources?
  22. Tim, What do you think of spraying a socket with deox (contact cleaner?) and letting it sit a couple of days, or do you just recommend replacing single wipe sockets?
  23. Looking at Characters that are produced more than once, I'm looking at 9 and 4 - It appear the character definitions are corrupt, because the characters are corrupted in the same way over again. So either VRAM or the source of the character definitions? Can you boot another version of MDOS?
  24. Tim, I might have asked this before, but... I have an original copy of SAMS Photo Facts for the 99/4a. Step 1 is always use your oscope to measure ... How can you fix the far more complicated Geneve's with out the aid of an oscope, in so many cases? Do you use an oscope / logic analyizer in your home shop?
