   I've had small caps blow in both a Kaypro and a BBC Acorn in the last
couple of months. In both cases, the machines kept right on working. OTOH
I've had large PSU caps short (not blow) in machines including an IBM 5100
and they shorted out the PSU so that nothing happened when you turned them
on. If I get a "dead" machine, the first hing I check is the fuse and the
second thing I check is the large filter caps.
