We've used these boards at work to upgrade several ageing machines
and I have one myself.  I plugged a spare 80-pin async cache module
into the COAST socket on mine expecting it to work - instead of which
it appeared to shut down the main PSU, perhaps by shorting a power
line.

Fortunately all was ok when I removed the module.

I'm sure the cache modules for these boards must be specific, and
probably have the cache controller chips included as part of the
module.
