Description
English: Acorn A500 second processor.I think that the A500 second processor must date from the period when Acorn were developing the Archimedes range. By connect a second processor to the Tube, Acorn could use the BBC Micro as the I/O processor and not have to worry about I/O devices on the A500.This board has been stripped of most of it chips. The board shows the following:
  • Sockets for 1 (or 4?)MB of RAM (on the right)
  • OS ROMs with yellow stickers (on top). I have not yet tried to read them to see what the OS version is.
  • Large square socket for ARM 1 or 2 (in middle)
  • 3 small square sockets for MEMC1 (on right?) and IOC (bottom left?) and VIDC1 (top left?)
  • Tube interface, scocket unsoldered (bottom next to RAM) with socket for Tube ULA above it
  • White keyboard connector (middle bottom) this is the same type of connector the A500 uses
  • Podule backplane connector (bottom left)
  • RGB socket (top left)
These are somewhat speculative due to lack of any documentation and the rarety of the board which means I have not been able to check it elsewhere.
