- Well, off hand I am not sure about j1-j5, but the switch
- is used to run the machine either in 6502, 6809 or a software
- controlled mode where you could switch the machine via software.
- The 6502 mode is identical to an 8096 (the extra 64K available in a
- selectable 4K bank) - the 6809 mode has all the Waterloo SuperPET
- languages on it - Assembly, BASIC, Fortran, Pascal, COBOL and APL
- plus a standard editor for all the above.
-
- My manual does not mention the jumpers at all. I could open
- mine up and see how they are set, if that's what you need, though.
