Sprow ARM7 Coprocessor

Description

The ARM7 coprocessor can be used with the BBC Micro as an external coprossor aor as an internal coprocessor for the Master. It has a 64MHz ARM7 with 16MB memory and runs BASIC V.

I decided to upgrade a Master 128  to the ultimate specification so I couldn't resist buying an ARM7 coprocessor, the fastest co-processor for the BBC and Master.
