I looked up those game watches. There were more in the line than I had realized. A lot of them were Nintendo licenses, but there were also generic games, plus miscellaneous licenses like Ghostbusters.

Didn't kevtris attempt to dump those electronically already?

Cool, the more testing material for SM530 emulation, the better =)
Let's hope they're not (unreadable rombits) Holtek stuff, like the Nelsonic Game&Watch minis: http://seanriddledecap.blogspot.nl/2017/07/blog-post_8.html

I also bought an IXO Telecomputing TC101. It's a handheld data terminal created by Holly and Robert Doyle, who created Merlin, Wildfire Pinball, Stop Thief and Code Name: Sector.

Can you give a brief hardware description? Or is it an epoxy blob festival?

Sean, LMK when you've scanned the background layer of Wayne's World =)
Starfox as well, but that's for later.

Those were used on a lot of the Coleco Telstar systems. Do the chips basically package transistor transistor logic into a single integrated circuit?


I haven't spent much time analyzing the dies, but I assume they are state machines. I'll try to get more for comparison. These 2 dies are broken up into several blocks, and there are blocks on both dies that are very similar.

I haven't gotten it yet. The patent says it's an 8085 with two 2732s, but I bet that was just the prototype. I found an article that says it has an NEC MCU.

I uploaded the backgrounds. Starfox is starfoxwatchbkg.tif

I've been trying to figure out the page order for the Starfox ROM, but I'm not very good at deciphering decoders. I'm fairly certain it won't be sequential; it looks like the lsb alternates, giving counts like 0132, 1023, 2310 or 3210. I assume the selection of top ROM array vs bottom ROM array is either by lsb or msb. I'm pretty sure the rows are the bytes in each page in sequence, and that the bit positions in each byte are 0-7 left-to-right.

Guess what came today?

It's got an NEC D7508C and a Motorola 40DIP labeled SC82014P. I haven't followed the traces to try to figure out what that is. There's also a 512x4 PROM and 1Kx4 SRAM. The built-in modem is an MC14412V. The LCD display is driven by two NEC D7227Gs.

It was powered by the phone line when off-hook, and by a Polapulse battery otherwise. I never saw those for sale individually, but my brother had a One Step camera and when he used up a film pack I'd tear it apart and remove the battery.

I also bought the video and serial/parallel interfaces for the TC101. The video interface has an MC6847 and an Intel D8749 as well as a 1Kx8 SRAM. The serial/parallel interface has an Intel D8748 and 1Kx4 SRAM.

Aw, uPD7500 series is not in MAME (yet)
This is not the same as uPD7500X UCOM-75 btw.

Got the one for Wayne's World, thanks! The one for Starfox is not there, a typo/case sensitive problem maybe?

I added a preliminary SM530 device to MAME. The disassembler works and can be used with unidasm.

Yeah, I saw uPD7508 is in Epson PX-4 and PX-8, but undumped. I'm going to buy a couple off ebay and decap them.

The Moto SC82014P is probably a 146805G2- I'll try to dump it in non-user mode like the other 6805s I've dumped. I wonder why MCUs from 3 different companies?

I'm not sure what I did with the Starfox background, but it's there now.

I got the other watches. Super Mario Bros is not an SM530; I'm afraid it's a Sanyo like in the SystemA handheld Haze sent me.
