Sorry for the necroposting - wanted to add this thread from VCFED: http://www.vcfed.org/forum/showthread.php?77055-NEW-Alps-printer-plotter-mech-pinion-gears

Nice work, @kl99!

Interesting how they still have a -5V rail.

I have a Pyuuta and @Tanam’s boards coming in from Japan soon, and I hope to be able to take a look at this system and figure it out. The ultimate cartridge sounds like I can use it to run BASIC. Has anyone reimplemented the Centronics port yet? Or adapted joysticks to Atari or TI joysticks?

Matt, do these work on the Japanese variant?

Here’s some pictures of the clear cartridge. The upper case is marked with SKU 1015919. The lower part of the case is marked with 1015918. The cartridge board appears to be a four GROM and one ROM. The GROMs are unmarked, -20A, -21A, 2022, and blank. The ROM or RAM appears to be an AMI with a date code of 7940SAJ. Part number 1501392-9. The TI PCB is 1015921-2, Rev B. No results show up for any of these ICs. Let’s crowd source check the pin outs here - I can help with continuity. Since this is 1979, I’m not making any assumptions on what this is and how it’s wired.

I believe he withdrew the CC-70 mockup - it didn't sell. Not sure what his plans are for it. As far as the clear cart, it's mine I'll post internal pictures as soon as I get it. That way we can see if all the pinouts are correct. It looks like it has three GROMS and a ROM.

Here's an English translation of http://www43.tok2.com/home/cmpslv/Pyuuta/EnrPt.htm - attached as PDF. Below are all the pictures from the PDF. CPU: System Rom: I/O: Keyboard and Joystick: Keyboard Matrix: TP1101 Joystick: Sound: VDP: Connector pinouts: 　　 64K cart diagram: Enri's Home PAGE (TP1000).pdf

Let’s make a thread for technical info as we get it, including: Joystick Pinout Expansion Connector Pinout Cartridge Pinout Memory map PDFs of any technical documentation (BASIC commands for assembly, etc.) It would be great to get a list going in a documentation thread with all known games and scans of the PDF manuals, including the user manuals. Lots of these systems come with no manuals, and these don’t seem to be readily available anywhere. Here’s a good start we will need to translate thanks to @tanam1972: http://www43.tok2.com/home/cmpslv/index.htm

Speaking of which, my copy of "A Christmas Carol" just fell on my foot. It hurt like the Dickens.

Wait a sec, you think we should jump into creating a sub forum for suggesting sub forums without a planning sub forum to plan it first? [emoji6]

Unless we can get the entire Tomy community over here...

The only place I was able to get Door Door was being sold a cartridge with the ROM on it from Tanam1972. Mine is en route.

As far as we know, nothing like that was ever released. The only development material released was the ALDS (E/A) cart and the documentation which Ksarul is about to scan in. Steve Reid likely has some data on the TI-74 side (he'd be the only source, though). I'm sure some of the data exists *somewhere* because of the special cartridges (drill bits, horse racing, etc) that was written for the CC-40, and the insurance cartridges which were written for the TI-74, but to date, nobody has found any.

And the person that needed to get it, Got it

I think that Ksarul is likely going to be bidding on almost anything interesting to preserve it - so if I see he's bidding on something, I'm not going against him. I don't want to make life hard enough for him - he's spending enough of his own money to help preserve this stuff for all of us.

And I said so in the comments shortly after he posted the video... the comments which are now no longer there. Sigh, Sent from my iPad using Tapatalk

Did he remove the comments? I did see the video in my feed and responded that the paper clip thing he did made me wince. Don’t see any comments on the video now. Sent from my iPad using Tapatalk

Ever wanted to see a Wafertape drive? How about a tape? Or a 10 pack? Had to remove some rusty screws and clean up a little rust on the IC legs inside, but the mechanism looks in ok shape.

I’m working on that :)

That's the CA-800 interface for the TI-88 calculator: http://www.datamath.org/Sci/Slanted/CA-800.htm

Nope, he’s gradually listing stuff. I’ve been helping him understand what he has. The cassette he has pictured is a wafertape, or “stringy floppy”.

Wouldn’t surprise me. I’ve seen other stuff he has, and some of it would blow your mind away.

I asked - it has an 8K 2564 in it. Just one. This appears to be the same unit as my 32K one, but it doesn't have the "dead bug" circuitry that enables a 32K ROM. It should work with the 24K ROM version, but would need the logic chip and mods to use 32K ROM. The 8K ROM - it might be a diagnostic rom or just an incomplete ROM set.
