You might also tell us something else about the machine:
- 6502 @ roughly 1MHz
- RAM expandable to 40kB
- Cartridge port
- 22 column screen
- Cassette and *floppy drive* ports. (yes, you weren't restricted to the lowly Datassette for your storage needs)
- One Atari compatible joystick/paddle port
- User port with TTL level RS-232 serial port
The user port, cassette port and floppy port were all compatible with the C-64/128 among other CBM 8-bitters.
