I knew I'd seen them somewhere. They're used as the writeable control
store RAMs in every classic PERQ after the PERQ 1 (that is, all models
with the 16K WCS CPU board). Few PERQs had Inoms RAMs originally, but I
have good experimental evidence that they work.
Speaking of which, I discovered that I've got
a bunch of InMOS 16Kx1
static RAMs (IMS1400S55) in gold-capped ceramic packages. Are they
used in any vintage equipment or are they better used as fodder for
the scrappers?
ISTR a Sun 3-something that used those SRAMs in some way. Cache, maybe? Possibly a Sun 3-110? The ones I saw
weren't gold-capped
ceramic parts, though, just ordinary plastic DIPs.
YEs, the one I stuck in one of my PERQs was a plasic DIP.
