That would certainly be handy!
The SLT is btw very reliable, MTBF of 50 year.
MTBF is a statistical measure valid only within rated operating
parameters of the device, including design life. It is not a
measure of expected lifetime of any single unit.
I don't know what the design life of an SLT module was, but it was
probably less than 20 years. Therefore these 40 year old modules
are at the very far end of the bathtub curve, and can no longer be
expected to conform to an MTBF rating.
By today's standards, an MTBF of 50 years for a small assembly of
solid-state components would be extremely low. For the mid-1960s,
it was quite good.
I am afraid that the CCROS in the /30 is a bigger
problem then failing
SLT.
Assuming that all the cards are physically present, getting it working
will be a hassle, but should not be completely insurmountable.
Someone wrote a microcode-level simulator of the 360/30 a few years
back, but was never able to locate a copy of the microcode to run on
it. :-(
