This is a new thread on an old topic.
I have responded to a a few threads here also to pepper in the files for those in need.
If you have a Two-Bits ABC Pac Kit, here are the files you need to convert from fast to reg speed, and also the Diagnostic Rom.
I know people poke at the diag rom a lot, but I find when I buy a batch of Pacs at a time, it is a quick and dirty way to test the boards and removes bad sockets from the equation.
It is also a quick and easy way to setup any Pac board with Pac or Ms Pac, Reg Speed or Fast with minimal effort.
Note, you can install a switch on the jumper on the board so you can switch between Ms and Pac, however, they will both run at the same speed based on which rom you burn.
Questions, please let me know.
Note Diag is 27256, game roms are 27512.
I have zillions of 512s if you need a set of all three I can burn and ship also.
Special shout out goes out to @coinopper for his help when I was looking for these a while back.
