More Microbee PCBs and Metal Work artwork - ChickenMan - 20-12-2020
Thanks to ejwords for making these available to be scanned. All scanned at 600dpi on an A3 scanner. While a few were A1 or A2 in size, most were A3 or smaller or actual size of the pcb itself. The larger A1 & A2 sizes needed multiple scans that were then later stitched together and reduced to A3 size.
The files mostly contain a positive scan of the wiring side, component side, solder resist, drill guide and component reference. But not all are complete with all of these, particularly the early S100 ones but they will be updated if any missing parts are ever found. A few include an actual photo of the component side and a few were updated with inclusions of further scans.
Of interest is the Edcom PCB's this is what they called the Microbee in-house before it was named. The mainboard is P/N 1248 Rev C and it was 1248 Rev D that went into the very first Kit Microbee quickly followed by Rev E and finally Rev F.
Some of these we dont have schematics for them, so they can be useful in tracking down issues.
So in the repository in the MbeeTech\Microbee\Documentation\PCBs folder we placed
