Commodore SX-64

The SX-64 repackaged the C64 with a colour display, detachable keyboard and built-in floppy drive in a robust transportable case.

It was the first portable computer sold with an integrated colour display and remains one of Commodore’s most distinctive machines.

Notable Features

• The keyboard clips over the CRT and drive for transport.
• Its altered ROM colours improve readability on the small screen.

Historical Significance

• It was the first portable computer sold with an integrated colour display and remains one of Commodore’s most distinctive machines.

Collector’s Notes

• Board revision, regional video standard, power supply, keyboard legends and original accessories should be recorded.
• Memory, storage, displays and expansion hardware should be documented because configurations often changed during a system’s working life.
