Unidasm on the 444 code gave a bunch of "invalid opcode" errors because it didn't like the opcode bit patterns for the extra address bit. Now that I think about it, that was probably just an output formatting issue, and has nothing to do with the emulation of the chip.

That mego sea battle has another unknown hughes LCD driver chip in it, too. I'm sure I can easily RE how it works by examining the 8048 code if/when I can dump it. Seems to be similar to the microvision chip, just a different resolution. 20*14 or so pixels but only 20*13 are hooked up. There's an NC pin on the chip in the middle of the LCD driver pins so it's possible it's a 34 output chip.

Pins 1-6 are the power+inputs to it, while the other 34 are LCD pins, except pin 21 which wasn't hooked up but I suspect might be another LCD pin.

Rik- To your knowledge, were the games in these 2 patents released? Thanks.

The first one is Look-Alive Football
http://www.handheldmuseum.com/Mattel/LAFB.htm

I have one of those... (They also prototyped Baseball and Basketball like this, but those were never made)
Baseball patent:
https://www.google.com/patents/US4395760

Don't recognize the second at all though...

Cool! The patent shows a COP421L, which is easy to electronically dump.

Mattel Auto Race does have a Rockwell B6000 chip as I suspected (BSG is B6001), and Football 2 has a new one: Rockwell B8000, which is a 40-pin DIP.

Three more: Castle Toy Co. Einstein (Simon clone) has a COP421, so that should be easy to dump. Tandy Baseball has a PIC1650A- maybe I can dump this one; I know Kevin can. Atari Touch Me has an AMI chip labeled C10745. I haven't checked the pinout yet to see if it's standard or custom.

I can dump the 1650 right now, btw. I got a Tandy Cosmic Fire Away 3000 today (aka twinvader III, which it says right on the PCB)

This has the exact same chip set that the Tsukada games have, a TMS1024 and an MP1604. both are 28 pinners. It also appears to have the same resistor networks too.

I found TMS1024's on ebay so we might want to get one of those decapped if we can't find a data sheet. I didn't have much luck when I poked around google. Apparently the '1024 is an "IO expander" which would make sense for a TMS11xx which has really crappy IO out of the box.

The 1024 should be fairly to RE too I guess since it'd be trivial to hook it up to my logic analyzer to probe how it functions. If it's an IO expander it should be extremely easy to figure out.

rik: sent back your games today

What's the full numbers on the chips for CFA3000? I have various 'Twinvader' games, if any of them are the same I won't need to send them to you... smile

"This has the exact same chip set that the Tsukada games have", but Tsukuda Pachinko is a 40-pin MCU, can't be the same as Cosmic Fire Away 3000.

Unrelated, this has been nagging me :P Anyone know what chips are in Milton Bradley Dream Phone?

I'd guess just a tsp50c10, given when it came out, and how it works.
