Will this memory modules work?

Well, they are parity, and 70nS. Most likely in the Model 90, BUT do
these have presence detection?

Somebody offered me memory modules produced by IBM. As he pulled them out
from a Compaq I would like to know for sure if they would work in my PS/2
machines (Model 55SX, Model 70, Model 80, Model 90).

The sticker on the modules says:
IBM 053 11E1360BA-70 MB 1M X36 P

The chips on the modules are produced by Siemens.

Regards,

Eugen

They probably will, if there are 9 chips all
identical. Some of the Compaq-compatible
chips with a parity chip in the middle, that
is different from the other 8 (but the same
nominal bit size) don't work in some of the
PS/2s. Won't hurt the machine to try.

These are 4Mb parity 70ns chips that should
have the correct/acceptable Presence Detect coding (pins 67,68, and 70 shorted
to pin 72,
pin 69 open), particularly seeing they are made
by IBM.

Have used a lot of Compaq-preconditioned
SIMMs in PS/2s -- most were from the Prolinea
466 series.
