Cool, another possible. Ironically I have a 9121 and a
9123, not a 9122.
Now to work out whether the difference is significant.
I think that other than the PSU, the HP9122 and HP9123 are much the same.
The HP9122 has an internal PSU (runs off the mains supply), the HP9123 takes
in +5V and +12V over that cable ending in the 5 pin DIN plug. It was designed
for use with the HP150-II which has a suitable power output socket.
