Ready to wire

11/15/2010

LC-81 is a Mini-Computer based on Zilog Z80 microprocessor. I've missed the excitement of designing the CPU but gained, in return, a very fast development pace. In fact, the LC-81 "CPU Board" was designed in three weeks in contrast to Heritage/1 which took me one year to (partially) design the CPU circuits.

I also built the shassis for the "Lab implementation" of the machine. Here is a picture:

Now I'm ready to start wiring the boards starting with the "CPU Board" which contains the microprocessor, the first 16 KB of memory, bus buffers and some other logic.
