Amazing! A computer made without microprocessor... or a processor made of TTL circuits. He has remade a system similar to the core of the great 1970's Xerox Alto / Xerox Star series :-) I never thought someone would remake a processor this way. I love that kind of madness !

Walter Belgers and Marcel van Kervinck's Gigatron (https://gigatron.io/ https://gigatron.io/) is also interesting. It's spirit is to use only 70's technology to keep the system "learnable" from the ground up, although they sometimes violate this rule for peripherals outside the main system. Walter gave a talk recently about it: https://www.youtube.com/watch?v=rbaAmnhZAis https://www.youtube.com/watch?v=rbaAmnhZAis
