Sounds good. Let me know when you're done and I'll paypal you return postage.

The Hitachi chip is from Mattel Armor Battle. The stenciling under the IC socket I installed lists 2 similar part #s, one for Armor Battle and the other for Sub Chase, so it might be a standard MCU that's just labeled with Mattel's part #.

When I get them back I'll torch them all and map the bits in the MM7x and D557 ROM arrays to your dumps, and see if there are any hints on the other 2 dies.

I got a melody madness and a cosmic fire away 3000 coming now so we'll be able to see what's inside both.. Hopefully there's not a TMS1xxx inside the CFA 3000

sean: OK. I will have to add some 28 pin sockets to my dumper boards to accommodate the new parts but this isn't a problem. I am also reviving my allpro 88 dumping addon device; are you interested in that if I do it? I think you said you had an allpro 88, right?

The idea is a PCB that fits inside the allpro and replaces the three power supply boards, and has a ribbon that plugs into the computer port, and has USB + 12V input on it.

I was thinking of adding a simple LCD (HD44780 type) and some buttons for "mass" dumping maybe. Like you get a tube of 20 EPROMs and want to dump them all, it'd be nice to be able to plug it in and hit the button to dump + auto create the file with an incrementing filename or similar.

I got a prelim PCB design done of the difficult parts (power supplies), so all that was left is an FPGA and some other gubbins to make it all work.



Also was going to add some headers for small fans because cooling is grossly inadequate IMO and make them turn on when the programmer is under bias (i.e. pin drivers are... driving). When not under bias it doesn't get too hot.

Dumping will be performed via "scripts" that are executed on the hardware, and consist of a 45 bit wide VLIW CPU running at 20MIPs or similar, with 8 32 bit registers and built in delay functions and 16Mbyte of RAM. Also was thinking of replacing the existing clock generator with an FPGA output to produce any frequency of clock desired instead of the fixed 5 or 6 the allpro normally does.

What was the status of the Coleco Frogger game? I can't remember if you were able to figure out dumping it or not...

I finally dug up a Gakken Frogger, and it's the same Konami chip, but with a different die code:
M58846-700P
(You mentioned 'P's once before, is that possibly a protected chip, or just a coincidence on this one?) The VFD is a CP5084 GLR, and is slightly different than Coleco's, but mostly in the art style of the sprites.

Another random game: Castle Toy Kingpin II pinball
http://www.handheldmuseum.com/CastleToy/Kingpin2.htm
It's an 'actual' pinball with ball and flippers, but runs on an NEC D550LC
It'd be fun to add that to Visual PinMAME as well... smile

Found a Rockwell B9001-13 in Mattel's Horoscope Computer. Where any of the earlier Mattel LED games (like Battlestar Galactica) dumpable, or was decapping used for that?

If there's an undumpable TMS and you don't mind losing it, I'm happy to visually transcribe the ROM.

Atari Touch Me, Castle Toys Einstein and Jimmy the Greek Blackjack are en route. I'm hopeful the BJ game has the Rockwell chip from the patent.

Interesting; B9000-12 is in Mattel's Brain Baffler.

I've decapped several of the Rockwell chips from Mattel games, but haven't figured out how to emulate them yet. It's definitely high on my list.

Kevin- yeah, the AllPro board would be cool. I connected mine to a PIC, but only coded up dumping (slow) for a few chips.

Yes I dumped it. The VFD artwork and the dump should be sitting in a /coleco frogger/ dir in the usual place. Hmm just checked. the ROM dump is not in there. wonder how it got left out.

I just uploaded the ROM dump and the disassembly of it. Interestingly they are using 3 instructions that are not documented. I know what two of them are- they appear to be a left and right rotate. I documented them in the disasm.

I know they are rotates because the code "makes perfect sense" for them to be that- I reversed the VFD scanning/display and button reading part.

Yes I can dump those; in this case the P does not mean protected as far as I know. the 701 I dumped was a P version too.

As for the rockwell chip I have no clue. if it's an MM7x it's probably dumpable; this would be tellable via the pinout. An NEC 550, let's see... Yeah looks like it's possibly dumpable; there is a test pin on it. This seems to be the same/similar to the 557 I have here I was going to try to dump.

Yep that's how I am using mine right now too. It's slow and it sucks and it's hard to program for. So that's why I kind of want to fast track the board. Then I don't have to keep making PCBs to dump chips.

I'll put together the info I've collected on the Rockwell chips. I've found 3 different families so far in the Mattel games: B60xx in Auto Race and Battlestar Galactica, B61xx in Football and Baseball, and B90xx in Brain Baffler and now Horoscope. I've looked closely at the B60xx and B61xx pinouts and die shots, and they are not MM7x, but I think they are related.
