I got Mattel Sub Chase and Tomytronics Break Up. Sub Chase uses the same chip that was in Mattel Armor Battle that I sent to Kevin.

Break Up has a 28 SDIP labeled MP2726 and a TMS1025 40 SDIP. I decapped the MP2726 and the die is marked 1040B. That makes it the first TMS1040 I've seen. The only info I've found is on Datamath.org. The only pinout I have of the TMS1025 is on the one-page "Texas Instruments Microprocessor and Memory Products TMS 1000 Family Pinouts" sheet, but they swapped the pinouts for it and the TMS1200.

I also de-globbed Sears Auto Race. It looks like instead of an MCU that it has a custom VLSI, like Simon.

I'll put together some pictures.

Dumped most of the micros from this lot; having trouble with the HD38820A88/89 though; the data is coming out off by 1 somewhat randomly; guessing I am not clocking it fast enough or too fast, so I might have to dork with it.

Both amadar and jungler have the konami logo on the CPU, and the konami name/logo is on the PCB also; both use an itron VFD like on coleco frogger, too. Fairly interesting.

I wonder if konami designed these for coleco, but then coleco stopped selling them so they got CGL/gakken to distribute/make them.

Mattel Auto Race should have a Rockwell MCU, is the Sears one a newer release?

Yeah, TMS1025 is an I/O expander like the 1024. Did you trace it to understand how the chip works? If not, I'm sure we can find out with trial & error. A pinout would be awesome though: which pin goes to which LED, which TMS1040 pin goes to which TMS1025, etc.

TMS1040: can you see differences on the die when compared to the standard TMS1000?

kevtris: with more of those Konami (Mitsubishi, was it?) MCU dumps now, I'm confident enough to start a new mcu emu core =) - the more 'test cases' the better

Mattel Auto Race has a Rockwell B6000, which looks like the same B6001 that's in Battlestar Galactica, except for the ROM. There are no identifying marks on the Sears die except RMR-0012. So I'm not sure if this is a licensed Mattel cost-reduced game or if it's a knockoff.

I will trace the pinout of Break Up and post it with the other info.

I haven't composited the TMS1040 pics yet, but visually it looked similar enough to a TMS1000- ROM, RAM and PLAs in the same places. Datamath's comparison table shows all the same info as for the 1070.

Which Sears Auto Race do you have? (There's two, one where the track is horizontal, and the other one has a vertical track like Mattel)
http://www.handheldmuseum.com/Sears/AutoRace.htm

I don't think Sears ever licensed from Mattel. I know the horizontal one is a licensed game from Tiger (Tiger Raceway, their clone of Mattel's game).

The vertical one appears to be licensed from Dynamic Toys (I think they are the maker)-
http://www.handheldmuseum.com/Misc/DynamicToysDynamicRace.htm

There's a couple knock-off versions of the vertical format that got licensed all over the world it seems...

I have both of the Sears games, if I can find them I'll take a peek inside and see if they are the same chips or not.

I have the vertical one that looks like Dynamic Race. The PCB has a logo that looks like TCL : www.seanriddle.com/searsautoracepcb.jpg

The die just says RMR-0012.

I guess those traces that have been drilled out are for testing that the PCB was made correctly? I see that all the time.

usually those holes are there to break all the circuits apart after gold plating. the routes are all joined so that they can be plated, then they are punched/drilled to break the circuits apart.

I uploaded info on Castle Toy Co Einstein and Mattel Funtronics Red Light Green Light. Both use Nat Semi COP MCUs; RLGL has a COP410L die bonded directly to the PCB, and Einstein has a COP421 (not L). I had to lower the voltage on SI to 1.5v to get the COP421 to go into ROM dump mode. I dumped RLGL both visually and electronically. There's one bit under some dirt, but it's difficult to clean because I don't want to damage the bond wires. I did wind up breaking the bond wire to the green LED; I've been careful with the board, but something must have touched it. Maybe it happened when I removed the plastic that covers the LEDs.

There are a couple of crappy videos of Einstein to help with the timing:

Your Einstein dump is incomplete? COP42x is 1KB.

I forgot to mention that- it dumped 512 bytes of 0s as well. So I guess they only needed 1/2 the space? I disassembled the code and didn't notice anything obviously wrong (like calls to the other half of the address space), but if there are issues, I can decap the chip and check it out.
