Very cool, Mike. 

My 3029 has the MB8877_ <-No 'A'.  Anybody have any idea if this is
significant, speed-wise?
I'm very tempted now to get out my Disto schematics and bash them
together with yours to get a high-density controller with a sector
buffer for no-halt operation, and a 28-pin EPROM socket or two.  If I
did attempt to build such a thing, I would start over on a new PC board,
just using the MB8877 chip and the data separator from the original
controller.  I've got a homebrew CNC PCB drill press that's just waiting
to punch holes in some copper-clad...
