Designing RISC-V and VGA output and 4 I/Os using discrete components only no FPGA nor microcomputer

Czech student Filip Szkandera has spent two years building RISC-V with eight custom printed circuit boards without using an FPGA / microcomputer. Filip Szkandera is presently attending the Vocational High School of Electrical Engineering in Olomouc, Czech Republic.

Leftoverture: In the early 1980s, I remember debugging a breadboard of the DMA controller for 68000 by myself. 40 custom boards fully mounted with TTLs are mounted on a backplane in two rows of rack. This was the way mini computers were built in those days. Senior engineers responsible for logic simulation visited once every three days to make logic corrections. My job was to reflect the changes on the breadboard by wire wrapping and soldering. Around the time thickness of the jumper like hair became about 1 cm, they decided to make chips. I realized three years have passed since I started on the job.

Doing work without getting paid would require tons of  talent , independence and discipline. A future is bright for techs !
