I've emailed the gent about the haul - I haven't heard back yet. Someone
may well have beat me to it. No biggie as long as it's rescued.
Thanks for the heads up (for whomever ends up with this stuff)

PICKUP ONLY in
the Seattle, WA area (I live about 15 mi north of
Seattle). I'm happy to drive out a ways (say, 2-3 hours) to meet you
Why can't things like this be near London (England)? :-)

(works, but floppy controller is not happy)
The real reason for my reply, for the benefit of whoever rescuses this
fine machine.
The floppy controller PCB contains a little buffer RAM, 256 bytes. It's
made of either 256*4 or 1K*4 SRAM chips, in the latter case 2 of the
address pins are tied to ground so that only 256 locations are used.
Using 1K chips seems ot be more common, and, you guessed it, they're
2114s. I've fixed a number of 9826s and 9836s by replacing those RAMs.
