Good question.
Easy answer: replace the chip with an exact duplicate using the spares you
have been picking up all over the place! If it has a little aluminum
covered chip - grab it!
Tough answer: I am not sure how much the S/370 logic would like working
with 10K ECL, but one could burn a PAL to do the required function. S/370
chips were not very complex at all - easily functionally replacable with
the ECL 22V10s. The PALs may also fit!

Very true. I do not have any real big iron (I wish I did), so I guess I
can not comment. RCS/RI can keep a PDP-12 operational most of the time,
like my PDP-8/S, but they have their bad days. The RCS/RI VAX-11/750 can
stay up, but that is about it.
