Notes:
1) For 8KB versions of the monitor, the bank switching is done with the bit 7 of REG1.
2) VID_RD1 : [7..0] = I0,R0,G0,B0,I1,R1,G1,B1 (I=Intensity,R=Red,G=Green,B=Blue)
3) VID_RD2 : [7..0] = I2,R2,G2,B2,I3,R3,G3,B3 (I=Intensity,R=Red,G=Green,B=Blue)
3) REG1 : [7..0] = EPROM Bank,-,Modem,K7,I,R,G,B (I=Intensity,R=Red,V=Green,B=Blue)
LIST OF MONITOR COMMANDS (all addresses must be 4 characters)
C Load a file from tape
D Load DOS from floppy
E Load a file from tape and run it
G a Go (a = address)
M a Memory dump (a = start address) Use the arrow keys to move around.
R Reset then load DOS from floppy
S a b c Save memory to tape (a = start, b = end, c = exec)
KEYBOARD
- When started, the Lock is engaged, so numbers appear as symbols. Hitting
Shift will unlock this and return the keyboard to normal.
- To use the natural keyboard, hit > (or some other shifted character),
then proceed as normal.
- To paste, use the emulated keyboard and hit Shift, then do the paste.
- The monitor command-line cannot handle the arrow keys or Del correctly.
- It is thought that the BASIC cartridge has better keyboard handling.
TODO
- Cassette
- ACIA
