More Microbee Schematics - Modems, Network, Printers, Coreboards and more - ChickenMan - 28-12-2019
Thanks to ejwords for making these schematics available for scanning. All were A3 or larger and all scanned on an A3 scanner at 600dpi. Finally converted to B&W pdf's.
Some of these are updates replacing existing schematics where we had only A4 sized and/or were lower dpi scans.
All of our schematics now named with their Microbee code number as well as a description of what the actual schematics is. This make locating and filing easier.
More will follow.
So in the various folders of MbeeTech\Microbee\Documentation\Schematics we placed

RE: More Microbee Schematics - Modems, Network, Printers, Coreboards and more - ChickenMan - 29-12-2019
Here are a few more Schematics, with thanks to ejwords for making them available to be scanned. Again all are A3 in size and scanned at 600dpi.
The 8303_microbee_printer_interfaces.pdf replaces our existing A4 sized microbee_printer_interfaces.pdf. The viatel.pdf is only designated as viatel. The mb8309_rompak_ver2.pdf also replaces our existing A4 sized scan.

Thanks to ejwords for making these available to be scanned. All scanned at 600dpi grayscale on an A3 scanner.
Found were 2 very large originals in A1 size of a missing Alpha Plus (Premium) schematics, 1 of 2 and 2 of 2. It took 9 scans of each on an A3 scanner to scan the whole schematics with plenty of overlap which were them all spliced together. The final joined schematics were then reduced to A2 size.
The other was a large A2 sized schematics which took 3 scans on an A3 scanner to scan all with plenty of overlap on each for easy joining.
So in the MbeeTech repository in the Microbee\Documentation\Schematics\Main_boards folder we placed
