I’ve got one working fine thanks to assistance received here! You do need
to tell it current date and time over the SCPI interface to sort the 1024-
state, but while remaining powered up it should be fine. I added a battery
backup to the Oncore board to speed up startup in future after a power down.

I found it helpful to get the oncore board functioning on its own first
(you simply need a psu and rs232 to ttl adaptor). The winoncore software
still worked on win11 (found I think on KO4BB).

There are potential tantalum capacitor issues - and they may cause
collateral damage. I had to replace one and a transistor which had
self-decapped.
