PDP-8/L & DF32 disk on FPGA

As final entry in this PDP-8 saga (for now), I’d like to present an FPGA implementation of a small but very functional setup by Ian Schofield of a PDP-8/L with serial console and a whopping 32-kiloword disk drive. All available for $25K at the time (PDF). Ian’s project is for the Cyclone III of an old’ish Nios II Embedded Evaluation Kit. Luckily, the DE0-Nano has enough on-chip BRAM memory to take its place.
