48/80 FORTH

This was a port from a Forth Interest Group source. "I did this before I worked at Sinclair, and sold it to East London Robotics who at the time were making a 32k and paged 64k ram extension. They purchased it I think because they had people buying their 64k hardware but with no applications which could use it, and so they had to answer the question of what could you do with it!"
