I had no idea a Lisa was a handheld game running on a 4-bit microcontroller ;-) No wonder the driver's all wrong!
What is the current setup people are using to dump COP 420's? I was going to try dumping all the HP-HIL chips. The last one I did was for Looping back in the 90's. I think I still have the code for talking to a PCI parallel port card that I used.
