Home Page Forums MAME MAME TMS-09xx/1xxx thread (was New Dumps)

Is it possible to do that without killing the MCU?
That is, to make handheld lend-outs possible.

Fortunately with Game&Watch, the PCB pics I've seen have the MCU chip and not an epoxy blob.

That's the question. From my experience, I don't think I could.

It doesn't look like I transcribed the TMNT ROM from the die, so I'll work on that. I did type in the patent ROM, but it's scanned, photo-copied, dot-matrix printer output, so there are likely some errors. I can cross-check it with the die dump after I finish that.

I also typed in Contra from the patent, but I don't have that game.

topgun.svg link is broken btw

*edit* What is the number of the contra patent?

Erg- probably don't have SVG's whitelisted. I made a ZIP: www.seanriddle.com/topgunsvg.zip

Contra is US5120057

Would be awesome to see R-Zone emulated.
Some people claims that's a crap system, but have a inestimable historical value

*edit* some information can be retrieved in this website: http://www.consoledatabase.com/faq/rzonefaq-sylvaindechantal/
It seems that had 27 games released.
Some merchandising scans also can be senn in this link: http://www.vintagecomputing.com/ind...gers-r-zone-a-lesson-in-how-to-look-dumb

Interesting fact:
In Brazil, Tec Toy distributed R-Zone, but from reports from users, it seems that only the cartridges which came in R-Zone itself was compatible with the system (cartridges which came with other consoles doesn't work), and it's unknown if cartridges was available to buy locally.

Another interesting TMS MCU to dump/decap might be in the Capsella CRC 2000 (https://en.wikipedia.org/wiki/Capsela)

My audio dev friend Chris Randall has posted a photo of his acquisition here:

Asked him to open it to know what sort of MCU it had, and from the photo, I'm pretty sure its a TMS1400 or similar (same pinout and markings as my Coleco Talking Teacher)

looks like a fun creative/learning toy, I didn't hear about it until now.
MP1359: our serial numbers list suggests 13xx is for the TMS1100

My *guess* btw as to the MPxxxx markings with the MSl△xyyzz style datecodes (with 5 digits; the old ones use 4 digit YYWW year + week datecodes) is:
MS - ?
l = location of manufacture?
x = last digit of year (first digits are 198)
yy = week during year
zz = day during week (first digit is always 0)

Fuck, Capsela! That's one part of my childhood I'd completely forgotten. Capsela was the shit when I was growing up, second only to LEGO. Thank you for the nostalgia trip!

I uploaded the TMNT ROM dump transcribed from the die shot. As expected, the one typed in from the patent had a bunch of errors, but comparing the two, I'm confident of the file. The only differences between the dumped file and the patent file are the 64th byte of each page. I guess they didn't license TI's method of detecting all 1s and forcing 0s to get all 64 counts.

I also posted the melody ROM. It's the same except that the patent ends with 5 $FFs, but the die has $00s.

I don't have a Contra to decap, but the printout in the patent is pretty sharp. I'll double-check what I typed in previously.
