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

Back on page 61 I posted a lovely pic of a dirt speck

Here's the worst VFD to date I think. It's a late game so it seems the VFD tech advanced a bit before it was made and they were using it to the fullest.

This is the last Rik game I have to vector, and all are dumped except for the SaG TMS chip and the 8048. I think I can dump the 8048 but I have to set up the allpro to do it.

I picked up Tandy Baseball and Entex Color Football. I got sniped on a cheap Entex Soccer because I forgot to check the end of the auction, but quite a few of those show up.

Here's the whole board:

I can put up the back side too if it will help...

I think the other games in this series (there's two more) will be similar. They have anime characters that appear all over the screen...

Doraemon: emulated and working. It's a fun game! =) Even has a short background jingle that doesn't annoy you.

VFD Artwork link reminder (bdoramon can be downloaded there soon): http://dspnet.fr/~galibert/artwork/
kevtris: If you do an update to svg's, could you do it on these instead of your own? due to them having grid/plates numbered.

Any MESS dev here that wants to do Entex Select-A-Game?

it has the MCU on-cartridge, comparable to MB Microvision. 1 cart dumped so far.

Damn! That chip has a datecode of 1982, so it almost certainly has the FuF protection. We could dump 7/8ths of it electronically (and there probably is some as-yet-undiscovered way to get that 8th bit out too), but it really needs a decap to get everything.

There exists a possibility of doing a 'live decap' leaving the bond wires and legs intact of a chip when decapping it (hence leaving the chip alive/functional; this was successfully done by digshadow on the upd1771 scv sound mcu before we knew how to electronically dump those), but it is much more involved than a normal decap is.

Rik-

If it's not a big hassle, a pic of the back side could be useful to insure that the pinout matches the TMS-1100 and they didn't switch to another chip.
The PCB layout is extremely similar to RTD; some of the LEDs are in different locations, but the parts seem to be numbered the same, and even the jumpers are in basically the same locations.
It's interesting that the chip has 6011 printed on it; that was printed on the RTD PCB, under the chip.

I just double-checked, and my RTD had a B-revision in an SDIP. But as LN said, I'm not sure if Bs were still made in '82. I'll check some Microvision carts that I have.

I've still got several of Ranger's Microvision carts along with some that I bought, and I found duplicate carts where one has a B-revision and the other has an E. The PCBs are different revisions, but the OSC cap and resistor are the same. I'll put the carts back together and confirm that E runs faster.
