Already been there. Jameco has been a long time supplier I've used going back to the 70s.
Looking at the various board there is a lot of repeated circuitry (mostly for bus) so I'm
looking at if I do this how to cut the total parts to soem much smaller amount but
full ram/eprom as needed. The FDC board was a cluttered mess, that was a an
easy reduction with the first section to go being the PLL data separator it was
complex and tended to misbehave.
