F21Chip

F21 was ahead of its time as a $2 chip with a 200 mip Forth processor, an independent 40 MSPS D/A and A/D coprocessor subsystem, an independent video io coprocessor, and a smart network routing processor allowing the Forth CPU to execute remote proceedure calls over the network with a one microsecond latency. F21 also had a real-time clock, parallel port, timer circuit and 8-bit and 20-bit SRAM and DRAM interfaces.
