And here are the ones that I scanned- DM-53, DJ-101 and ML-102: www.seanriddle.com/gandwbkgs.zip I cleaned them with water, but that didn't seem to do a lot. I was worried about using window cleaner on them, but I can if you think that would help.

Those scans look great smile
Currently MAME's svg renderer (we use nanosvg) doesn't support embedded images though. And simple MAME external artwork won't work either: it's designed with bright screens in mind(eg. CRT), black pixels on top of a backdrop will show as transparent. The only option is external artwork made with OG's svg2lay tool.

Great! It is interesting to compare our ml-102 scans. Some color differences that may be due to fading?

Yeah, my ML-102 background plastic is very wavy, so it was probably left out in the heat.

Rich Burbage emailed me asking for info on Dark Tower. He's doing board repairs and has found 6 different PCB revisions so far: http://www.voiceofthemummy.com/Pages/CircuitBoards.aspx

The TMS1400 on the newest revision has the TMS1100 pinout. I'm guessing TI did a cost reduction by removing the extra I/O (the 28-pin TMS1400 and 40-pin TMS1600 have the same die, but the extra pins aren't bonded out on the TMS-1400). So it is essentially a TMS1100 with double the ROM and a 3-level stack.

The SM510 datasheet says "the system clock has a frequency of one second that of the oscillator frequency". I think that's a mis-translation of one half, which matches what JR55 was doing. The SM511 has a selectable 8.192/16.385 kHz system clock which defaults to 8.192 after ACL. That matches what I see with BX301.

I dumped JR55 with 4 clocks per byte, so I was sending doubled-up opcodes and then missing half the data. That doesn't explain why S2-S8 weren't working, though. I assume that was due to some kind of damage.

ML102 also outputs a byte for 2 clocks, so I expect it is also an SM510.

Do you know the process of choosing the 16kHz clock? The datasheet just says it "can be selected by instructions", but I didn't see anything obvious in the instruction set.

SM511 emulation in MAME hit unknown opcodes sometimes, the timing suggests these are for the instruction clock divider. If you still have a SM511(or in the future), try:
$60 $36 for 16KHz instr. clock
$60 $37 for 8KHz instr. clock

I made an attempt at scanning JR-55 LCD's, uploaded to the same place: https://www.dropbox.com/sh/p3dv2vovpbb786k/AADOyFnkr-qbRo5zEDBokAOJa?dl=0

They at not nearly the same quality as Sean's scans, but hopefully they are still usable...

The upper lcd throw-hand and thrown-key IDs were the wrong way around in the .svg(both activate at same time), I corrected it now. And one of the broken handcuffs was missing.

Hap- I will try those instructions. Last week I tried to control an SM510 still on the G&W PCB, but didn't have any luck. I'm not sure what I did wrong, but I'll keep trying. The idea was to dump ROM without removing the chip, to send opcodes to turn on each segment individually to map them, and also to test opcodes.

Jonas- JR-55 looks good! Some of the panels are easier to photograph than others. I tweaked the contrast a little and I can see the "traces".

I got my LCD panel PCBs and they look good, but I'm leaving for Houston in a couple of hours for an all-week business meeting. I had an internet outage this morning that turned out to be too much being downloaded from my web site, so I had to stop the web server. I'll try turning it back on tonight. I've been migrating the big pics, but there are still several gig on my server, and my internet is too weak to support someone downloading everything or many people hitting me at once.

Heh, I checked slashdot to see if they mentioned Ken's article, but nowhere else. Unfortunately I won't be able to do anything to fix the problem until this weekend. But I'm guessing most of the traffic to my site will die off today.
