Below you will find pages that mention the tag “cpu”
The control panel of the “R 500 / 7 T” computer at the Enter Enter Technikwelt Solothurn museum. It is a relay based rebuild of a Konrad Zuse computer. I love the sound of the machine when it is calculating. And the best of all, you were allowed to operate it!
It’s alive – not yet a valid program, it is just executing NOPs right now.
I made good progress on my CPU design in the last two days. It’s starting to come alive.
The first simulated “program” running on my own instruction set. It takes more time than expected but from here it’s mostly repetition to finish it.
Designing a CPU you can actually still build with discrete elements and has a useful set of capabilities is quite complex project. And a significant trade-off between features and complexity. Just adding one register more makes it much more complicated than I expected.
