All:
I'm playing around with my relatively new IMSAI and I was
pondering the following. The unit is constructed with the front panel power
switch unconnected and the corresponding terminals on the power supply board
jumpered together. There is a mains switch on the rear panel which takes the
place of the front panel switch.
While for safety reasons I cannot disagree with the approach -
it's plain stupid to put uninsulated mains voltage in a low-voltage area
(and unpassable by UL evaluators I'm sure) - it detracts a bit from its use
because you have to reach behind the unit to turn it on.
Has anyone come up with an elegant solution to being able to use
the front panel power switch while keeping it safe? I was toying with some
sort of low-voltage circuit (small LV transformer and relay, with the front
panel switch in the loop on the coil side). Another idea I had was to hot
glue a dielectric insulator board (that gray cardboard kind of stuff) over
the parts of the front panel that would be exposed.
Ideas? Too much time on my hands?
