Motorola EXORciser II

The EXORciser II updated Motorola’s development platform with a faster MC68B00 processor, improved debugger hardware and space for as many as ten optional assemblies. It supported increasingly complex 6800-family software and hardware projects.

Its combination of modular expansion, disk operating systems and in-circuit development tools served professional embedded-system engineers into the 1980s.

Notable Features

• Selectable 1, 1.5 or 2 MHz clocks supported several 6800-family targets.
• The DEbug II module offered eight terminal baud rates and EXbug 2 firmware.

Historical Significance

• Its combination of modular expansion, disk operating systems and in-circuit development tools served professional embedded-system engineers into the 1980s.

Collector’s Notes

• Systems vary greatly according to fitted memory, emulator and disk-controller cards; retain card inventories and software media.
• Memory, storage, displays and expansion hardware should be documented because configurations often changed during a system’s working life.
