Since I have a small number of 74LS83s in my parts bins, I might have
to try that if I end up verifying that I have a dead 7482 on one of my
M220s (from an -8/L, in my case).
I think I've seen 74LS83s for sale somewhat recently (at Unicorn or
some similar place).

Agreed for
many parts of 1990s machines, but as for 1960s and 1970s
DEC machines in particular (the subject I know more about than
others), there are a few parts here and there that are getting
difficult to find without robbing them from other machines - Omnibus
buffers come to mind first, and certain parts from the -8/i and -8/L
era, like the 74H40 or the 7482...
...There are of course many work-arounds if you don;'t mind minor
kludges -- one of the M-series boards in my RK11C has a dead-bugged
74LS83 (IIRC) replacing a dead 7482. Works fine. Things like that.
