Bill Sudbrink asks:
How many {ADM-3A's} are out there, just on this list?
One here. ADM-5, I think. Similiar looking. No eBay.
(This was found, hanging above the floor, face
down only by its cord, pushed off behind a
table next to a networking wireharness, One
small island of HW in a building being gutted
just last year. The ADM had been forgotten but
was still running happily. A workhorse.)
