BeebEm - BBC Micro and Master 128 Emulator

Acorn Z80 Co-Processor

BeebEm emulates the Acorn Z80 Co-Processor board. The Acorn Z80 was a CP/M based system running with 64KB RAM on a Z80 processor.

You start the Acorn Z80 by selecting Acorn Z80 Co-Processor on the hardware menu. If you load a CP/M system disc in drive 0, the system will then boot to an A: prompt.

A CP/M Utilities disc is in the 'DiscIms' folder which will boot the system. The Acorn Z80 originally came with 7 discs which can be download from Jon Welch's web site - Acorn Z80 Discs.

These discs contain the Acorn Z80 application software including:

CPM Utilities
BBC Basic
Mallard Basic
CIS Cobol
MemoPlan
GraphPlan
FilePlan
Accountant
Nucleus

You will also find some manuals for this software on the site as well.

The Acorn Z80 should also run most CP/M compatible software but no guarantees are given for what will and what won't work.
