  1. I'm trying to identify this board I picked up in a haul of various old computer items. I'm not familiar with which computer it belongs to, but I did find this old thread My board is comparatively less complex, as you can see in the attached pictures. Any idea for certain which computer/interface this connects to? I don't have a Coleco ADAM and am unfamiliar with the expansion ports on it
  2. Just recently picked up a Microvision with one of the worst rotted screens I've ever seen. I'm very interested in one of these.
  3. I figured I'd give this a shot; is there any interest in e3, e5 v1/v2 era Xeon server equipment? I have a lot of 8gb and 16gb ddr3 ecc registered server memory, chassis from pizza boxes, 1u to 4u jbods. Most of the boards and chassis are Supermicro, though I have a few Dells and other misc. On the high end, I have some e5-2620, e5-2650 v1/v2s (would need to double check on the v2s, I have v1s for sure), that's dual 6/8 core, threaded cpus in a board, up to 384 GB ram, several removable drive bays. I have a number of 480GB SSDs and 1-3TB SATA drives, enterprise/datacenter grade. Please keep in mind that this is all used equipment, I can provide readouts of SMART data on the drives as I know some may have a number of power on hours. I also have boards that will fit an ATX case, and the e3 cpus will fit in many Sandy Bridge or Ivy Bridge chipset boards if you want to build a beefy workstation. I'm looking for 80s-90s non PC compatible computers, game consoles and oddities. Especially interested in imports, MSX, PC88/98, Sharp 68000, FM Towns, Amiga, Atari 16-bit, Tandy computers and real oddities. If you're interested, let me know what you have. I'm aware that I have few posts despite being a member here for years, and I mostly just lurk the Marketplace. I can provide pictures of anything there is interest in, just let me know what you're looking for. I'm located in the Phoenix area and ideally this could be locally arranged, but I'd entertain cross shipment depending on what's on offer.
  4. Would these work in other computers/consoles that use a TMS9918 series VDP that outputs YPbPr, or is this specific to the Colecovision and Adam?
  5. Do you have any references or transaction history? I'm interested, but leery of the low post count and no record of past transactions.
  6. Put me down for one "Assembled device - $50". How much would shipping be to 85225?
  7. I bought an Atari 800XL computer in rather excellent condition. Communication was great, everything was packed to survive a nuclear holocaust, and he even undercharged me on the shipping. I wouldn't hesitate to deal with grips03 again.
  8. Why not both? That way you can bump the thread when you have an update, and people who enter on page 1 will have the most updated info as well.
  9. I've thought about the f18a, but being VGA kills it for me.
  10. I've seen Yurkie's mod, but I'd like something that doesn't require an upscaler (especially a specific one) and keeps as close to what's output natively by the VDP as possible. If I wanted it converted to RGB, I already have my own external solutions for that. Also, Yurkie doesn't appear to offer a DIY kit, which is exactly what I want.
  11. Color me very interested in this as well, I've long been meaning to add a component mod to my Coleco and this pre-made board looks perfect.
  12. I meant that I tried the file intended for Classic99 on real hardware for the hell of it, even though as you explain earlier, it's designed specifically to work with how Classic99 expects things to be. It was more of a 'why not?' than anything at the point I tried it. I haven't tried the backwards file in Classic99 at all. Is there a particular PLCC flash you'd recommend yourself over the 29f040, if it happens to be the problem? Actually has anyone else tried this on an ÜberGROM board and gotten it to work successfully? Looking back through the thread, all the reports of success seem to be from those using a 512k rom board with eprom.
  13. I'm having less luck getting this to run on my ÜberGROM board that came in the other day. I tried both the latest 'non-backwards' file in the zip from page 5, as well as the one from the 512KROM.zip attachment on page 2. Both were detected, the former displays 'For Games' as option 2, and the latter shows "Menu". Both boot into a cyan screen, same color as startup, and the computer promptly locks up. I don't have an Atmega in place for GROM emulation if it matters. Currently I am using the PLCC socket with both AT49F040 flash chips I received with the board. My programmer has had no issues on programming the chips. The programmer software verification passes every time, and I have manually verified that the code that is read back matches the original file, both prior and after inserting it into the ÜberGROM board for testing. Something interesting of note in my tests with commercial roms: first I programmed an image of Adventure, and did not fill in the excess after the 8k of code. The result was a cart with Adventure in the first 8k of space, followed by the former code from the current multicart image beyond the first bank. When booted, it showed the same header from the multicart image, '2. For Games' instead of Adventure. Afterwards I duplicated the Adventure rom across all banks, which didn't work either, but did display 'Adventure' correctly. I assume Adventure came on a grom instead of rom, as I then programmed Nature's Way in the same manner, which did boot correctly. Beyond this, I did try the inverted version of the file for Classic99 for the hell of it, which didn't work either, as expected. I take it that this is this a positive sign that my board is booting from the highest bank instead of the lowest? Is there another possibility? What if it lands in a bank inbetween, currently assumed to not happen? Any idea on a possible internal revision in TI-99 computers that might account for the problems, some difference in wiring/data paths to/from the program module port? Assuming the chips are being programmed correctly (between 2 chips and all the verifications, I don't think it's on the flash or programmer end), and considering that the image of a commercial game that came on a single rom with no grom works fine, what could be the problem? Did I miss something about this multicart image requiring the GROM emulation function provided by the Atmega, which my ÜberGROM board currently lacks? Could it be a flaky PLCC socket on the ÜberGROM itself?
  14. Payment and PM sent back at you. It sounds like I picked a good time to unbury my TI-99 and decide to actually do something with it. I'll probably be performing one of the internal 32k memory upgrades as well. It's just too bad this is a US unit with the composite video out, I'd really love to hook up RGB out up to my PVM, even though the rf alone is some of the cleanest I've seen.
  15. I have a 32-pin PLCC to DIP adapter for my burner, so programming one is no issue. I'd prefer flash over eprom anyways, saves time on erasing the chips. Simply using it as a rom cart for the time being is enough of a toy for me while I figure out how I want to handle acquiring the ATMega. $23 for an UberGROM + a pair of blank flash chips sounds good to me, even if it is a prototype. What's your paypal?
