We put in enough R134a to just barely fill the sight glass -- maybe
that was too much!

Absolutely too much R134a! That's what's happening. The cold plate
overflows with R134a which dumps excess liquid into the compressor. This
blows the hot compressor apart as the liquid instantly turns into high
pressure gas, boiling off inside the little cylinders.

There is a specific amount of R134a to put in every system, just enough to
make the whole cold plate cold, but not enough to dump excess into the
compuressor. You can no longer look at the sight glass and just keep
filling it like the old days.

There's your compressor blown problem.
