Keeping old computers and electronics alive

AT89C51-8051-8031 SBC

The schematic design (made with Kicad) 8052Sys2019_CPU-2019_08_06

Stripping Atoms

As my 2 Acorn Atom boards were in a quite bad state, and I got a hold of a desoldering station that worked pretty well I decided to strip both boards “to the bone”, and rebuild them with high-quality IC-sockets, low profile crystals etc. (Board images are clickable for Hi-Res).
