I was buying electronic stuff from some guy yesterday and he showed me a pile of these boxes. Only one was assembled (these pictures) but the rests are diy kits with all the materials and manuals, I think it's pretty interesting and I would have buy one if it wasn't for the reason that lately I hardly have time to breathe or even posting this thread

so what do you get, an incredible high quality PCB, excellent ceramic with golden pins Z80, I/O interface similar to an ISA bus (but it's not of course) 2Kb of ram, some ROM with debbuging software for assembly programming, 3,5mm jacks for your datasette , an Hex keyboard and a very limited 6x 7-seg display
