This modern expansion board for the BBC Master uses the Tube interface to add an ARM7 co-processor. It 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
  • Supports high speed SDRAM from 8Mbyte to 64Mbyte
  • 512kbyte on board flash ROM (containing system software and BASIC)
  • Optional 4Mbyte external flash ROM
  • Optional serial EEPROM for parameter storage
  • Optional RS232 port and JTAG for debugging use

The coprocessor is supplied with a simple operating system installed, which repackages system calls (called SWIs) into the corresponding BBC Master compatible call and sends it across the Tube, as well as providing a handful of standalone calls and general program environment.
