The EFA microcomputer in slo-mo

Magnus Kesselmark


I just ordered an 1851 PIO and a PCB for the EFA computer as published in the book Elektronik För Alla (1983). The EFA computer is very simpel as is the PCB, but I wanted something to assemble my ELF on and I will skip some parts and wire the extras up on loose boards. Guess I will end up mounting just the 1802 on the board ...

For anyone interested, here's the supersimple diagram:
And this is the board layout:

Knowing myself, this will enhance my chances of getting something working ....
