Excellent to hear!
Some of the #'s seem to already have been labeled as a "success". However, I'm sure the Doc knows what he is doing 
Also, does anyone know anything about what's going on with hooking up the Revolution X PIC16C57 in MAME?

I'm looking forward to #123 C-chip and #17 Qsound should be interesting.

#107 needed a higher magnification of the die to verify some questionable bits. based on what i read in the shout box earlier this year.

#123 (the C-chip from Bonze Adventure) is unfortunately dead and cannot be completely read out; the EPROM die on it is damaged. We will eventually need another one.
The C-chip as a whole is a very interesting contraption:
It consists of several "chips" crammed onto one IC, a lot like a successor to the Toshiba T5182, but made by probably NEC instead. It contains:
* One Mask-ROM NEC upd78c11a (upd7810 compatible) w/4k of mask ROM (this is intact on chip 123 and will be read out, but is probably the same on all the various C-chips)
* A battery-backed ?16k? NVRAM chip (which may also act as the upd78c11's external ram)
* A ?16k? EPROM (this is damaged and cannot be read on chip 123)
* An ASIC Logic array to tie everything together (this will probably eventually get imaged and traced out, as there may be a way to read the EPROM contents without actually decapping the chip at all)
#17 is an AT&T WE DSP16A processor with a 4096x16-bit NOR ROM which either needs to be stained to show the bits, or, more likely, to be similarly bus-attacked as the upd77c25 chips were.

This was done tonight/last night.

I already bought another Bonze C-Chip but he needs to do a successful read of a cheap/common C-Chip first, like Op Wolf IIRC...

Excellent work!
Also, to whoever runs that decap site, the progress and about tabs say "404 Not Found."

Could be from some recent mw changes, I'm sure it will be sorted out within the next few days.
