Some Microbee PCB artwork scans - ChickenMan - 28-01-2020
Thanks to ejwords for making these available to be scanned., All scanned at 600dpi on an A3 scanner. While a few were A3 in size, most were smaller or actual size of the pcb itself.
The files generally 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, but will be updated if any missing parts are ever found. A few include an actual photo of the component.
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

RE: Some Microbee PCB artwork scans - ChickenMan - 25-02-2020
Thanks to ejwords for making these additional pcb's available to be scanned. All scanned at 600dpi on an A3 or A4 scanner. While a few were A3 in size, most were smaller or the actual size of the pcb itself.
Some of our existing files have been upgraded with further additional scans added. A couple are overlays only and there are a few early Pre-Microbee S100 cards, one titled 589 but have no idea what the actual card is.
So in the MbeeTech Repository in the Microbee\Documentation\PCBs folder we placed

Thanks to "someone" for providing a scan of the EDCOMP computer, an early prototype of the Microbee. Its actually featured in the Owen Hill discussion on Youtube - https://youtu.be/aYNRcn9gg5A?t=189
Having recently purchasing a Matilda PCB off eBay, 600dpi scans of top and botton are also included.
