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.

The board comes with the following features:

• ARM7TDMI processor at 64MHz
• 8kbyte unified cache to speed program execution
• For internal use within a Master series or external use with the entire BBC microcomputer family
• 16Mbyte high speed SDRAM
• 512kbyte on board flash ROM (containing system software and BASIC)
• Expandable to up to 64Mbyte RAM and 4Mbyte flash ROM (external)
• Optional serial EEPROM for parameter storage
• Optional RS232 port for debugging use

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

Full details of this unusual Coprocessor are on Sprow's web pages .
