This is the port of pet2001fpga.

Installation:

Copy the .rbf file at the root of the SD card. Copy roms (.prg,*.tap) to PET2001 folder.

Notes:

  • PRG apps are directly injected into RAM. Load command is not required.
  • TAP files are loaded through virtual tape input. press F1 to issue LOAD command, and then choose TAP file in OSD.
  • F12 opens OSD.

System ROM structure

  • 0000-0FFF - unused, all zeros
  • 1000-7FFF - mapped to 9000-FFFF

Disk support

Core supports D64, D80 and D82 disk images through two 4040 and 8250 IEEE dual-disk drives. When using a D80 disk image, the first disk access will result in an error. This is normal behaviour of the 8250 drive.
