Clone of original ORIC ATMOS 1983. Very interested computer from past. Works on 6502, has 48k memory. Actually it was not very success computer, but … this is a reason to build this one. I order clear PCB and start building by myself. Board has errors. Another part of R26 should be connected to ground (nearest C10) (picture 1). Pin1 of IC20 not connected. Should be connected to nearest via hole (picture 2)....
