The later model 500/5000 have a small NiCd as well.

I've been helping the MAME guys simulate a

I had bought this a while ago, and never dumped the firmware. Unfortunately there is a
large
NiCd battery right in the middle of the board that leaked all over. I've taken some
pictures
which are up under falco on bitsavers.
If anyone has one of these, you want to do battery mitigation ASAP. I'm in the middle
of replacing
every socket on the board since they were all within range of the leakage corrosion.
Also, I suspect the first generation of terminals all have similar hardware with
different
firmware, so if someone has any of the other models (TS-1, etc.) we could get them
simulated
pretty easily once the firmware is dumped.
