The recent discussion on BSC protocol prompted me to
dig out my Microvax
3100
with DSH32 synchronous serial interface. It had been idle in storage for
several years and it wouldn't power up, only giving a brief flash on the
diagnostic LEDs and a quick twitch of the fans. There was a slight smell,
like
the stale air that comes out of a deflating tyre.

If anyone has anything with H7821 power supplies in
them, I suggest
checking
on these capacitors. If anything with these power supplies is in storage,
I
suggest ensuring it is stored the normal way up as this should limit the
ability of the goo to escape and spread around the power supply.
And there I was thought I was being safe enough by removing the nicad
battery
packs some years ago...

Thanks Peter..My 3100 just smoked up the other day, needs repair or a new
supply.
