  I have a PB copy of about that vintage if someone wants to scan it. It's
at the warehouse so I don't have it in front of me but it has all of those
old PROMs in it.  I also have a PB copy of the 1971 Signetics "Digital 8000
Series TTL/MSI" databook and 1972 Signetics MOS Silicon Gate 2500 Series /
Metal Gate 2000/2400 Series Data Book and 1978 Harris Bipolar CMOS Memory
Databook.  I have more old memory data books but they're not here at the
moment.
