Yeah, I got the Cosmic 1000 in a lot buy. I was able to dump the lower 7 bits (using R15 instead of R10), but I couldn't get the high bits out. Then when I blow-torched it the plastic stuck on the die and I had to boil it in nitric acid to clean it up. I chipped a couple of edges, but got lucky and the ROM and PLAs were OK.

It's possible that the Cosmic 3000 TMS is a different revision and all 8 bits could be dumped.

Conic(Cardinal) Basketball is emulated and working. I still need to finish the internal artwork.

While I was googling for reference bezel pictures, I found there is another version: MP0910, PCB CONIC 101-003

Regarding Cosmic Fire Away 3000 aka Hanzawa Twinvader III: it's MP1604. I don't know what TI MCU that might be, we don't have other ones in the same number range.

Nice! I see those basketball games on ebay from time to time; they are sometimes listed as "Electronic Readout Systems". I'll look for a cheap one.

I uploaded info on Tiger 7-in-1 Sports Stadium: http://www.seanriddle.com/tms1400.html#7in1
Note that the source code lists it as having MP7303, but this one has MP7304. The die also got stuck in plastic, so the top metal pic is ugly. But it whinked up nicely.
I don't think I got the overlays, but I'll double-check.

7303 was a typo by me I guess.
It looks like Rik has the overlays too, and also for the Sears version.

Yeah, here's large photos of them all:

I can scan them if we need/want cleaner images...

I added 7in1 to MAME, it is playable but behaves erratically depending on R10/K1248 value. Can you double check the input matrix?

I left off 3 diodes; the 3 anodes are connected together and to R10. The cathode of one is connected to K4, the cathode of another to K8, and the cathode of the third is connected to one pole of the 2P switch (the other pole connects to K1).

I got the Mattel Dalla$ board game- another one with lots of parts to make it difficult to emulate. You play it with a calculator that has a COP444.

Ok, maybe 2-player mode is simply a bit buggy: after selecting a game, skill-level and game-select are still controllable with P1 up/down.

I posted the Dalla$ COP info: http://www.seanriddle.com/cop400.html#dallas
I'll scan the board and pieces later.

unidasm -arch cop444 doesn't recognize the extra RAM and ROM in the COP444. I noticed this before but thought it got fixed. I just checked git and it's still an issue. It affects the disassembly of JMP, JSR, JP, LBI, LDD, and XAD; the jumps need an extra address bit and the others need an extra Br bit. The Dalla$ ROM dump has over 100 invalid opcodes with the current code.
