Emulator Shield Built

A project log for ED-64: A discrete 8-bit computer

ED-64 will be an 8-bit computer built with discrete components, and will feature a ferrite core memory (documented as a separate project).

The emulator shield is done:

I've written a program in T-1 assembler that simulates rolls of a dice. It uses a 32-bit Fibonacci linear feedback shift register to generate a pseudorandom bitstream, which is sampled 3 bits at a time to produce a pseudorandom number from 1 to 6 (0 and 7 are discarded):

The 8-bit input port is just used to generate a delay.

I'll upload the code soon.
