- 687, 1325
- 875, 17

maybe bad: bitmap x,y=
- 1673, 2067
- 2798, 17
- 2844, 17


I see 2897,17 and 2844,17 are the bits under a smudge, and 1673,2067 has dirt or damage to the bit. But 687,1325 looks OK (0 bit) and 875,17 looks OK (1 bit).

I'm pretty sure about the 3 "maybe" bits- take a look at the space below those bits; you can see a faint line, the same as under other 1 bits that have zeroes below them. Unfortunately, I lost the Plus One die, but I do have a top metal pic. The top smudge is there, too, so you can't directly see 2798,17 and 2844,17, but 1673,2067 looks good.

Hmm, I see now why. The plusone.bin on your site is different from the one I had downloaded at back in 30 april 2015, maybe you post-corrected some bits back then?

Of the GIMP picture you linked, I only extracted the die photo (bit mask was completely black on my picture viewer app). So I had to make a new mask from the old downloaded plusone.bin and compared it to that.

For Coleco h2h stuff, if Rik's list is complete the only one remaining is Boxing. That has a TMS1xxx according to the patent. patents linked from here: http://www.handheldmuseum.com/Coleco/H2HBoxing.htm
RB: They're essentially the same game, I'll only need to make 1 generic internal artwork.

- Hockey https://www.youtube.com/watch?v=U-Afgoql5yA

*edit* except, Coleco h2h game system, wth is this? :P NES on a chip thingie? https://www.youtube.com/watch?v=sseZKhZmRww

Oh, haha. I figured out how they'd turn soccer and hockey into the same game, but not basketball. Makes sense now.

That plug-and-play looks like NES-on-a-chip, although it could be u'N'SP like a lot of the other plug-and-plays too.

Yeah, think "1950's college basketball". Pass-pass-pass-pass-pass-pass-shoot. wink

Yeah, it looks like I updated the bin on 10 May 2015.

I'll look for H2H Boxing. It seems like I bid on one a while back, but must have lost.

It looks like I damaged the TI35 die too much to read the bits visually. I must have cooked it with the blow torch. I'll see if I can pick up another one cheap.

I visually read the bits from the TMS1000s in Entex Soccer, Conic Basketball and ELECSonic Football. I had dumped the lower 7 bits from those electronically, then dumped the high bits by executing each opcode and checking the program counter. They all had several "ambiguous" bits where I couldn't tell if the opcodes were jumps or not. It turns out that 3 in Soccer, 1 in Basketball and 4 in Football were not jumps, but all the other bits matched.

Also, I've been helping a guy dump the TMS1100 from the Radio Shack Microcomputer Trainer. He got it working, but it's a rev E, so he only gets the lower 7 bits. I just gave him my code to get the high bits, but since they are visible in my bad decap, he combined those with his dump to get a complete image. I'll document that and send the link.

The luck with the Radio Shack Shack Microcomputer Trainer makes up for the broken TI35. =)
I hope we can eventually emulate TSI Speech+ as well, with this method. It's too expensive to be worth decapping. And Rik if you're reading, Black Knight Pinball(was that the name?) is a possibility too.

Wonder if Raise the Devil is identical ROM-wise.

The chips in Black Knight and Raise the Devil are labeled differently, so the code is likely different.

I uploaded info for ELECsonic Football (TMS1000). It uses a DS8874N 9-digit shift input LED driver. The PCB is labeled Conic. http://www.seanriddle.com/tms1000.html
I also have another Football in the same case that uses a PIC instead.

I picked up a TI-35, BA-35 and TI-30-III. I think they all use TP0456 chips.

hehe, ELECsonic Football (TMS1000) == http://www.handheldmuseum.com/Conic/Football.htm
I'll start working on adding it to MAME.

I posted the Science Fair Microcomputer Trainer info: http://www.seanriddle.com/tms1100.html

The pics are pretty bad frown

Gakken made a replica a few years ago:
