I was picking up a load of Sun VME-bus equipment today
and ran across
some memory boards. These are definitely not for the suns, neither
multi-bus nor vmebus. The boards are perhaps 12"x16" and are populated
with what I presume to be memory chips (AMD 21-17559-01 / 8333EMM)
in 16 banks of 9 chips each. The connector along the back has 6
distinct edge-card pieces, with 18 contacts per connector per side.
That sound a lot like memory for a VAX 11/780. The one I have
is a 256K x 39 (7 of the bits are for ECC), but the previous
owner removed some of the 4164s.
