Someone must have the same board > somewhere Hi to all! Perhaps i have what you are looking for. It is a VT100 from 1980 with a video board that seems to be the same as yours. The transistor CR400 is a SANYO B411T? and this is a 2SB411 germanium PNP transistor mounted directly to the pcb without heatsink. Where to share photos of the board with you? --
