I have a few original ROMs and zero RAMs. I have to check to see if I have a chargen ROM or not, but since what I have is pulls, I'm guessing not. I probably have leftovers from Original PETs that were upgraded to 2.0. > Conversely, what do you need, in case I decide to go that route. I have to sit down with a ROM list and see what I have before I could answer that. Two 6550 RAMs would save me the hassle of building an adapter for the video RAM. I'm OK with using a PETRAM board for main memory rather than trying to find two banks of 6550s. > What we need is some kind of RAM/ROM registry like they have for organ > replacements... ;-) No doubt. > Did ya ever get that 2001 board I sent you completed and PETting away? I did not, unfortunately. I got as far as getting a 3032 board from another list member working with a chassis-type DC PSU and one of the ancient PET-to-composite adapters, but I never succeeded in getting a stable picture. I could see that the PET was running, but the best I could get was a slow roll on an ancient B&W 9" "security" monitor. I wanted to get the static PET working, but I ran out of time in the winter to make ROM/RAM adapters from scratch (I had much less free time this deployment than on previous deployments). I did get the board cleaned up and ready to work on, but not as far as applying power. It's a project for this year. If nothing else, I can temporarily mount it inside a 3032 (2001N) chassis and use the monitor from that for debugging the static PET board. -ethan Message was sent through the cbm-hackers mailing listReceived on 2009-05-07 06:12:53
