#cosmacelf — Public Fediverse posts

Je viens de remettre en route le #CosmacELF de @F4HRE (fait avec le PCB de ce projet https://github.com/tebl/RC1802-Cosmac-ELF ), j'en avais aussi construit un avec un PCB qu'il m'avait envoyé, donc je me suis dit que c'était une bonne idée de vérifier qu'il fonctionne toujours !
J'avais un peu modifié le circuit pour qu'il fonctionne avec les afficheurs de la description originale plutôt que des 7 segments, et aussi changé l'oscillateur à quartz pour pouvoir ajouter plus tard la partie vidéo.
Bonne nouvelle, ça marche encore 😁

Cosmac Elf - Blink using a Kim UNO Board

I saw this video about the Cosmac ELF which was a DIY computer from 1976.

I was fascinated with this. So naturally I went to eBay to see if I could find one cheap. No luck, but I found this KIM-UNO board that is a #simulator / #emulator for the KIM-1 - But someone made ELF firmware for it - so I picked it up.
Modern DIY ELF LOL.

@cr1901 The COSMAC ELF may be the lowest part-count microcomputer to have a (minimally) functional control panel without any ROM.
