Actually My comments were narrowly aimed. the IMSAI
was a far better
example of S100 and worth copying. Only ONE change I'd do... NO MAINS
POWER ON THE FP! Back when I'd seen one altair and a IMSAI fried by
someone comming in contact with that. It had no business there.
You know, 20 years after I first put an IMSAI together I still reach in
them today to wiggle around the front panel and YIKES!!. I just never,
ever learn!
I never fried any hardware due to the 120VAC, just me. (Once a screwdriver
ended up in the wall.)

Hi
I have no problem with it being on the front panel. Why does
anyone have trouble with that but not with the hot fuse on the
mother board. I have been bitten by the fuse several times
( slow learner ) but not once by the front panel.
By todays safety standards, the IMSAI is a failure but for
its time, it was well designed.
The only objection I have to the switch on the front
is that it is too close to other switches that might
accidentally be selected. Even there, one could still
do damage to running code by hitting some other wrong
switch. I rewired mine from the under sized switch someone
place on the back of my machine to the original switch on
front. It works just fine.

Trick showed me by the guy I got my IMSAI from:
Cut the bottom off of a Tic-Tac box. Makes a perfect cover.
In all the time I've been working on mine, must be more than
30 hours now, I have not taken a shot from the front panel.
Of course, I've been warned.
