| 13 | Bx = Boot from device x (0 to 7) |
| 14 | Dx [y] = Dump memory (hex and ascii) in range x [to y] |
| 15 | Fx y z = Fill memory x to y with z |
| 16 | Gx = Execute program at address x |
| 17 | Ix = Display IN of port x |
| 18 | Ox y = Output y to port x |
| 19 | Sx = Enter memory editing mode, press enter for next address |
| 20 | Mx y = unknown (affects memory) |
| 21 | Tx = unknown (does strange things) |
| 22 | enter = dump memory from 9000 to 907F (why?) |
