- Plan-80
-
- 06/12/2009 Skeleton driver.
-
- Summary of Monitor commands:
-
- D - dump memory
- F - fill memory
- G - go (execute program at address)
- I - in from a port and display
- M - move?
- O - out to a port
- S - edit memory
-
- ToDo:
- - fix autorepeat on the keyboard
- - Add missing devices
- - Picture of unit shows graphics, possibly a PCG
