SA1000 adapter board assembly

See here for usage information

Digikey is the only place I found an oscillator which could be programmed to the needed frequency so I am only providing a Digikey BOM. Edit as needed for your usage. Add as ordering note Program oscillator 510CAB-AAAG to .27125 MHZ. If all the parts show up as invalid refesh the page. It seems to sometimes do that.

The board files are here and information on files is here. See board license

If using the short connectors for P7 & P11 in the BOM R3 and R4 will need to be installed on the opposite side of the board from how the silkscreen indicates for the unlabled revision of the board. The silkscreen was corrected for rev B

X1 pin 1 is in the upper left. On the sikscreen its in the upper right.

X1, U1, U3, C3-C5 only needed for reading Shugart drives which need external clock. Emulation for all drive or reading Quantum drives don't need the clock.

If you are only using the board for reading or only for emulation you can not install some of the connectors.

P5 is not needed.
