What is the Burroughs part number / printed on the chip? The 1449 1112 RAM
chips are Burroughs' part number for the intel 2102 RAM

Soldered or socketed?
I'm on the lookout for 16 (or more to have some spares) 2102s to populate
an EconoRAM S100 memory board to go in an Altair. Proviso being they have
to be 'fast enough' (<=450nS, not sure whether 650 would be OK or not).

Speaking of gold-plated chips, I'm finally
scrapping the last remnants
of a
Redactron mag card word processor; the main board
has some house numbered
white ceramic chips with the usual gold pins and lids (24, 40, 16 pins).
(Could probably figure out many of them with some rev-eng'ing to get their
pinout.)
