New years treat!

[P-Man]

hi all,

Something we have been wanting for many years... I bring you...

Century CVS system schematics!

Kevtris did all the work, I provided him the board.

Happy New Years 2026!

PS - if you spot errors or omissions (invariably there will be) post in this thread and i'll ask him to look again for an update!

V1.4 Schematic update, and now including PAL dumps with JEDs! Now you can replace those pesky PALs with GALs when you find a bad one!

I can recall, quite a few years ago, Mike C stating that the ROMsets in MAME were decrypted and would not work with the CC1 IC. However, I have a ROM board with CC1 in place running Heart Attack and the ROMs match the MAME ROMset. At the time I thought no more of it.
After reading the text file in the above .zip, I decided to dig my boards out and have a look at rigging up the empty ROM board I have. When I got to the Heart Attack board I decided to have another look at it and discovered this...



The reason why the MAME ROMset works on this board is because the IC itself has been modded.
(I didn't notice the missing legs until I lifted it today.)

looks factory done, either that or the bootlegger was very neat!
