Sprow ARM7 Coprocessor

[Back ]

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.

Where to Buy

Full details of and how to buy the ARM7 Coprocessor are on Sprow's web pages .
