I looked around the board more and found "POR" etched on the board next 
to where the orange wire is soldered in and "P5" next to where the blue 
wire is soldered in.


"P12" is etched at where the yellow (+12V) wire is soldered in. "GND" is 
at where the black wires are soldered in. "N12" is at where the white 
(-12V) wire is soldered in.


How should POR be wired?

through the sun4m lunchboxes. The sun4m pizzaboxes went to an 18-pin 
power connector with the same wire color scheme, except gray became 
"PwrOff"/"Poff".


The PSU in my Axil 320 (a SS10/SS20 clone) uses the 18-pin connector 
and a color scheme similar to the SS10/20 one but I haven't checked 
all of the pins to see if they are completely the same.

If there is money to fund this effort, it might be worth talking to Iron 
Mountain, to see if they can handle the media.  They have people that do this 
sort of thing, AND, I know for a fact they have hardware to handle some strange

None of us are sure.  The Sony DVR units have been pretty easy to find but
the possibility of messing up any of the tapes even as a test ties everything

At this point Im going to have to get the superbeta and svhs machines

I've been really surprised how much news that made. I've seen it get asked

Given, I've never heard of the format so maybe I'm being naive.
