Casio FP-1100

The Casio FP-1100 was a professional personal computer with a Z80A main CPU, separate I/O processor, high-resolution colour graphics and disk expansion.

Its unusual dual-processor design and strong display modes made it one of Casio’s most ambitious non-MSX computers.

Notable Features

• Separate processor handling keyboard and I/O
• High-resolution monochrome and colour graphics
• CP/M support with disk system

Historical Significance

• Its unusual dual-processor design and strong display modes made it one of Casio’s most ambitious non-MSX computers.

Collector’s Notes

• The keyboard, monitor, disk interface and system software are specialised and often separated from surviving units.
• Memory, storage, displays and expansion hardware should be documented because configurations often changed during a system’s working life.
