I discovered Ive got an extra Ms. Pac Man Service manual. This includes all schematics.
I also have a Hard Drivin' manual that I don't need anymore. This is for the sit down version and includes a backdoor sheet and a Race Drivin' schematic package.
See pictures for condition...
€10 for each excl. shipping.

You're a true friend delivering these in person ;)
Hard Drivin' yes this is interesting from a technical point - not that I have a machine in sight yet.

I will join you, just to be sure that you don't leave them behind on the plane. LOL

That's the spirit Erik ! Then you can carry the Ms.Pac-Man manual and I can carry the Hard Drivin'...so our carry-on luggage won't be too heavy ;D ;D ;D
Speleo: yes indeed Hard Drivin's hardware is quite interesting. Jed Margolin did some clever tricks on it to get more out of the hardware. He even put in several tests of the hardware in several processors...pretty amazing stuff:
http://www.jmargolin.com/schem/schems.htm
Also note that Jed says there that the Schematics that Atari released were deliberately missing parts to "prevent" bootlegging. So don't expect the Race Drivin' schematics to be complete, but you can find the missing stuff on the above page by Jed.
This is my favorite part:
If you ground pin 4 on the TMS320P15 (signal 'P2') and then reset the chip (turning the game off for a few seconds and then turning it on again will do the trick) the TMS320P15 will send the Atari Games copyright message in Morse code which can be received on a standard AM radio by holding it near the DSK Board. Tune around the AM band to get the best quality signal.
I added this to my Self-Test code so that in the event Race Drivin' was pirated I would be able to tell if the program in the TMS320P15 had been reverse engineered or if the chip's security feature had been hacked. (The Morse code program is not accessible from the game code.)
As far as I know, Race Drivin' was never pirated, although Hard Drivin' was.
The TMS320P15 was used in another game (Road Riot) that was pirated. When I checked for the Morse code program in the pirated game, it was played loud and clear. So much for Texas Instrument's claim that the chip's security was actually worth a damn.
