  1. I have to look, as I may still have the manual around somewhere (assuming it wasn't one of the things destroyed when my apartment in Turkey got flooded over 20 years ago).
  2. We went down this particular rabbit hole a few years ago. ISTR that the part number is on one of the console diagrams. What I can tell you, based on our last hunt, this was a plug style popular in the 1970s that didn't survive much beyond that. I don't think anyone still manufactures a compatible plug (although it is possible that someone does, or at least has some NOS stuff in storage). I'm pretty sure the connectors were manufactured by Belden, but Switchcraft and Volex also made connectors/sockets of this type.
  3. After deep hunting, I found the part number for the EPSON serial board: 8155. Thay have a picture of one with the box at Computerhistory. No luck on where mine might be though. . .and they sold for about $190 each at the end of 1983 (price pulled from the 11-83 issue of ETI). This version apparently has a 4K buffer, which means it is a bit later then the 8145--but it may still maintain compatibility, based on their numbering schemes and the board itself (part number match).
  4. They are most likely copies, Dan. Note the font difference for "RS232" as I don't think that text was even on the original CorComp manual. They may be from someone BITD (Legio Computers comes to mind, as they did sell CorComp equipment in Europe), or they may be a more recent copy.
  5. As I said, the version sold for the Tomy in Japan is not at all common. I actually expected it to go for a bit more because of the condition and the fact that everything was present. . .
  6. Actually, the discussion I had with @Shift838 was about the Ryte Date Microstuph PEB. They are rare in the extreme. I have the motherboard for one though--and no documentation. The Rave99 PEB is a slightly different story. I own one and a half of those (the half box was a gift from @Gazoo). My original box came with a set of layouts for the boards in it, and I may even have a set of schematics with the set (I was a preorder buyer, those items were sent prior to the delivery of the box to show status of the project). I'll have to go digging to see where the manual is now as I haven't needed to reference it for a few years. . .
  7. Yes, it is the same one. Three pages in the middle of the document make up a complete block diagram of the original 74LS2001 chip. I probably need to take that and make a schematic of it with the pins identified by number and name, as that may come in useful if anyone ever tries to replicate the entire chip. I like your solution replicating the ETI workaround too.
  8. In the case of the IDE Hard Disk Controller that you referenced, the only existing GERBERS for it utilize surface mount components. Note that you were pointed to his old site. The new one is here, but the data is the same.
  9. I suspect the switch is to slow the memory down to standard speed to allow certain software to operate properly. You will probably find that the switch selects between two different crystals--one that runs the console at 3MHz (12MHz crystal) and one that runs it at 4 MHz (16 MHz crystal).
  10. The price was not so crazy if the person was trying to get one with the Pyuuta box, documentation, and the original included cassette program. Those don't show up too often (about once every two or three years in pristine shape like this one). The actual cassette player was a throw-in bonus (and yes, I'm the crazy person that bought it --it was the last thing I needed to have a complete set of Pyuuta-related hardware, now all I need are the half a dozen tapes I'm still missing).
  11. The majority of the Amnion library can be found here. @hloberg has done a great job collecting a lot of TI resources and curating them.
  12. One of my machines fits that description. The other one has the 32K and video RAM upgrades.
  13. I just looked through the 1983 version of the console technical data book as well. It includes the QI motherboard schematics, but the only power supply schematic is the original one.
  14. One of a very small number of 99/4 overlays I don't have (I do have the US version though).
  15. Not a bad idea--plug extender that puts the TI receptacle outside the console and a DIN plug into the console hole. Then if you make the pinout the same on the DIN as the pinout on an ELPAC or meanwell, you could use any of them to power the console interchangeably.
  16. There are seven or eight disks in the old Amnion library chock full of Logo programs, including a few programs that go into the recursive, self-modifying madness that is possible in the language.

    See post #206--that is the current status from the author.
  18. Lots of Forthers around here, @XLERB?, so you will have plenty of helpers in your quest to learn more Forth. It is good to see another system return to life!
  19. It does have the advantage of replacing both the internal and the external portions of the power supply though, @JB. Anyone using one just needs to find a way to forcefully identify the fact that the console has been modified though (like a huge red sticker that says DC only inputs--an AC power supply will destroy this machine).
  20. Computergrafik/Video Graphes/Computer Art is the same cartridge as Video Graphs, but it is the European variant of the cartridge. As noted, it is multilingual, whereas the US version is not. The GROM number for Video Graphs is CD2019, and the numbers for the GROMs in Computergrafik are CD2041 and CD2042.
  21. I'm pretty sure the schematic for the QI power supply was included in the bag when Radio Shack was selling them as surplus TI parts in 1984/1985. I'm not sure If I have any bagged ones left to check though. . .
  22. These actually look interesting. With a slight modification to one of the power pins, it could even be used as a drop-in replacement for the slide-volume-switch 99/4s.
  23. I recently received a group of pages cut out of some Japanese computer magazines with various Pyuuta programs on them. There are 19 of them here, and I don't think I have ever seen any of them online. Cameron should add these to his Tomy website. . .as program listings for the Tutor or the Pyuuta are a bit hard to find. Some of the names are best-guess, since I don't speak Japanese, and the files are placed here both individually and in the attached zip file. The same group of paperwork had some other documents that I've never seen before, but I'll have to scan them some other time. Jump Jump(G-BASIC).pdf Memory.pdf Mini Lifter(G-BASIC).pdf Pyuuta Type-Ins (zipped).zip Robber.pdf Slot Machine.pdf Space Fight.pdf Tennis.pdf Traffic Cop.pdf Trapix.pdf Warship.pdf Bomber(G-BASIC).pdf Burger.pdf Butterflies.pdf Crabs.pdf Dress Up.pdf Fighter Plane.pdf Fighting.pdf Golf.pdf Hotel.pdf
  24. That seriously sucks. The only good parts of this are that no one was hurt and that he had documented the collection online. May he remain safe. . .
  25. The original ELPAC supplies were used is a lot of different equipment (not just the CorComp stuff for the TI), so they still show up for sale pretty regularly too. That gives you two possibilities: the original ELPAC or the equivalent Meanwell power supply. Do note that both companies make/made a lot of different variations of their power supplies, so look carefully to ensure the one you buy has the proper voltages, located on the correct pins, before you buy them.
