  1. Unbelievable, but it truly sold for the list price. His sold items don't identify it as something he accepted a best offer on. . .looks lke @OLD CS1 will be in need of a drywall patching kit soon--and hopefully, his fist doesn't impact with a stud or some other painful blockage inside the wall to add an emergency room visit into the mix.
  2. When Rave99 closed their doors, Cecure Electronics obtained the rights to the Rave99 products. When Cecure closed up shop, they sold their entire remaining stock and the rights to it to Richard Bell. Unfortunately, one of the storage units containing a lot of the stock/documents Richard purchased was impounded and cleared out by the storage unit owner because of some issues with the storage payments (IIRC). A lot of stuff was lost in that transfer. Cecure had the PAL equations, as they did at least one run of the boards sometime around 1995 or so. I know Richard has some programmed PALs, he may also have the necessary JEDEC files buried in the mass of things he received from Cecure. Having this set in the wild serves two purposes--it allows folks to repair the one part of the card that wasn't readily available and it gives me the last puzzle piece I needed to make a new board layout for Richard. As to the decoding, adding AMD/E would be a good idea to enhance compatibility. . .
  3. That makes this card reprodicible. . .I will work on a new layout with the AMA/B/C mod on it and ask Richard Bell if he's interested in doing a run of them, since he is the current owner of the IP for the card.
  4. TIC and A99 are also part of that repository (the last two folders). Note that the source included there is everything Al still has, so if some portions are missing (this is the case for TIC, IIRC), they probably no longer exist as source code.
  5. Some of the display data for the first screen may be in the ROM, which is what I have to check to be able to answer the copyright date question. As the GROMs are socketed, it is also remotely possible that the GROMs were placed into it at a later date. My board set machine was made in very late 1978 or very early 1979, based on the date codes of all of the installed components, so a 1979 copyright date is actually plausible. The GROM to manufacturing list from C.B. Wilson also didn't appear to include a console GROM set older than early 1979 either.
  6. I had some long conversations with the seller of this particular system before it was sold. He wondered what the handset was for--and I identified it and the need for the IR box plugged into the top of the console to make it work. He realized that he also had one of those in the box of TI stuff he bought from a retired TI engineer for a pittance and decided he had major gold in his hands. I made a reasonable offer for the pair--and I was ignored. That was when he put the machine and the IR set up for sale for the crazy price. I let him know that the machine wasn't a Dimension 4, told him what it really was, and provided a link to the other auction going on at the same time to allow him to compare them. I also made a reasonable offer for the set--using the price I had paid for the complete Dimension 4 in my collection as a reference, since it was purchased at open auction and was of similar rarity. He ignored that offer too. He did sell it in the end, but he failed to change the listing, so the buyer didn't get the Dimension 4 they thought they did. He also sold it for considerably less than his initial 20K demand, as he later lowered the price to 10K and then took someone's best offer for it. I don't think it ended up within the community either, which is unfortunate. The most important takeaway here though is that the machine in this picture is NOT a Dimension 4, it is one of the 1,000 or so 99/4 test units (prototypes) TI built before releasing it. Another of these test units sold for $1,500 or so at about the same time this machine was sold. That machine still had the brushed aluminum trim and the test certification documents matching its serial number (719, IIRC). This one with the damaged case does still have the serial number sticker (739, IIRC), and based on the data gleaned from the earlier one's paperwork, this one would have been built in the late summer of 1979 (July/August).The case for the 99/4 has the cutout to insert the IR unit, but the connector that would be on the underside of the cutout is only present on the Dimension 4, so it is pretty much useless when plugged into a 99/4 except as a non-functional display item. If you look carefully at the joystick, you will note that it has a lot of buttons--20 of them. A complete pair of them would thus have 40 keys. TI made a metal frame to snap the joysticks into, making the whole thing into a 40-key remote keyboard (and there was an overlay for that too to identify the uses of those keys). The pair of devices in this picture is apparently the only set of them that ever escaped TI or a museum. The Dimension 4 was also built in at least two variants. One with the internal speaker and a slider volume control and one with an audio out jack instead. I have a complete Dimension 4 without the volume slider, and a complete Dimension 4 circuit board set for the volume slider version. The GROMs are identical to the ones used in the 99/4. I still have to read out the ROMs to see where the differences are, if any. As far as I know, I have the only Dimension 4s outside of a museum. I would be pleasantly surprised by the appearance of another one if one is out there, just for the opportunity to compare the different builds and preserve that information for the community. @acadiel and I were able to acquire a set of Dimension 4 schematics (he posted them in the C. B. Wilson thread, IIRC), so a lot of the technical information is out there now too.
  7. @Schmitzi, it looks like the loader and the fille for MiniPede on that disk are for the Extended BASIC version of the program. Bonus here is that that version isn't trying to load into the cartridge space, so it might be more easily manipulated to make it into a FinalGROM image.
  8. I was actually looking at my copy of MiniPede. The box and manual were for the disk version--and all three load options were on the disk (I just need to find my disk).
  9. For those interested in oddball stuff, here's the period proper modulator for the 99/4. Same seller also has an external power supply of the same vintage.
  10. I just located the manual/box in my basement. The CSI disk version came with three flavors of the program on it: MiniMemory, Extended BASIC Assembly loader, and an E/A version. Now I just have to look to see if I still have the disk in my software master copy boxes. . .though not all of those are easily accessible.
  11. The box is probably the hardest part of that lot to find--and it was a bit rough from water damage.

    Eye Candy

    I haven't seen a set of these in a looooonnnngggg time. For some insane reason, I never did buy a set when they were available BITD and they have only shown up for sale a few times in the decades since.
  13. I'm not sure, truthfully. I think the CSI release was available on cassette or on disk, like many of their releases.
  14. probably pixelperfect80s. . .unless I miss my guess. On MiniMemory versions of Centipede, don't forget Minipede. It was ready for release (I even have it on a TI cassette--they were that close to release). The cassettes came out as part of a mixed grab bag of surplus TI cassettes sold by either Tenex or Triton. I think I bought three or four lots of them for the members of the K-Town 99'ers in Kaiserslautern, Germany. There were several copies of Minipede in the lots. I may even still have one somewhere. . .although CSI also released it later under their own label (and I have that one with the box/manual too).
  15. Hopefully, the dog in that photo is OK. . .although the positioning of the legs says that may be otherwise.
  16. I will look, as I think I may have bought that program BITD.
  17. Back while I was living in New Mexico, they performed this song on SNL. I said I liked the song--and everyone else in the house looked at me weirdly as they slowly inched as far away from me as possible. . . .but then again, I got that reaction a lot while I lived there. Another time I was in a VW Bug full of local people and a song I'd never heard came on the radio. I liked it and asked if any of them knew who it was, as it was good music. Right about then, the refrain started: running with the devil. Everyone in the car except for me was a seriously fundamentalist-type. I thought they were going to toss me from the car at highway speed. . .instead they dropped me off at the next cross street and I walked the rest of the way to where I was going.
  18. Here's another Argentine TI site. They have a lot of interesting TI data as well. The TI was manufactured in Argentina, using parts that were for the most part imported from the USA. The TI was only manufactured at two locations in Europe: Holland and Italy, with the majority of that production happening in Italy. The US also sent machines to Brazil and several other countries in South America, so PAL machines weren't a major issue (the motherboard was designed to be easily switched between PAL video chips and NTSC--and the rest of the chips were identical on both). The US also supplied several Pacific countries with both PAL and NTSC variants of the TI, so both were a bit widespread outside of the European PAL and SECAM units.
  19. Here are the schematics for all of the CorComp devices. The board you are looking for is one of them. . . CorComp Schematic Set.zip
  20. Well, that board does say it is for a 990E.MEM.204. . .on the front silkscreen.
  21. 39th week of 1981, LTA says it was manufactured in Lubbock, TX. On the Solid State Software badges, they were to hide the slider slot for the speaker at the back of the cartridge slot. These were only used for their intended purpose (with the volume adjustment slider) on some of the Dimension 4 prototypes (I have one of these) and early 99/4 machines intended for the European market (built in late 1979 and early 1980). I have one of those consoles as well. The entire top shell did not change for a long time, I suspect until the original injection molds wore out, as that would have been the least expensive solution at the time. At some point along the way, they did eliminate the cutout in the top of the case for the IR Joystick attachment (every 99/4 case I have ever seen still has it, though it is hidden by the top aluminum piece). Later replacement molds during the life of the 99/4A then eliminated the slider slot.
  22. 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. . .
  23. 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. . .
  24. 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
  25. B. R. S. would most likely be Bill R. Sullivan. . .so you would have seen that in some Forth+ documentation, @GDMike
