retrofitting something modern, but I figured I'd check here before I got
too far into that *just* in case.

It is not as bad as you think.  You could for example use a DEC h742, with
associated regulator bricks, to power the h316. Most are ok as is.
Exception being the h316 needs a 6v line.  You could tweak a h744 voltage
regulator to put out 6v rather than 5,  by using the built-in h744's
voltage adjustment  potentiometer.  In short look to digital equipm stuff,
esp. the pdp11 power supplies as there are some close to what a Honeywell
h316 needs.

Yes I looked into all of this when considering bidding on the h316, I
always wanted one of these. I have a lot of the docs
