I'll have to dig that out. The biggest part of that is power,
5V3A, +12 at .2a, -12 at .1A that excludes the floppy.
Add +5 1A and +12 1A per floppy. The base system does
single sided 40 track so most any drive works.
The other signals are jumpering baud rate clock to the
console port (normally comes from VT100).
Three of the 4 ports need to have their signals brought to
connectors, they originate on the 16 pin socket.
The last one is POR (power on reset).
One note: the base rom set comes up and looks for the vt100
(does a query for device) and requires the normal VT100 response.
You should also find a print set.

That would be great!
Only about 10 boxes to
look in and shed storage.
I've finally gotten the paddle board, just a few months ago, and now I
need to find (or more likely make) a drive cable.
I may have one of those floating
around.. Have to hunt for it. I also have spares (vt180 boards, Vt100 boards,
Vt125 board set)
for mine. Actually years ago (1985) I bought a box of VT180 boards
for $25 all good but none of the other kit. I use them standalone as
mods needed to make them run without the VT100 are trivial and
its a good 4mhz Z80 CP/M platform for project and things.
You've mentioned
that big stack of them that you scored. Very nice!
I have one spare VT180 board; I didn't know it was that easy to run them
standalone, but I guess it makes sense as it's almost completely
self-contained as it is. I'd love to try that. Can you share the info? -Dave
