I have rebuilt my Inovonics 222 clone on copper clad board instead of annoying stripboard

Mostly electronics and all sorts of synthesizer, he/him.
The descriptions on ebay get weirder, thanks to the "AI". Here an old HP CW sweep generator is described as a cow generator and is here to generate electricity from manure, or something? https://www.ebay.co.uk/itm/336025379743
Elsinør had a sleep on an HP 8903B recently. She loves to flop her head down from resting places. #Catsofmastodon
Another HF site with microwaves that are likely pointing at Buckingham Avenue. This year’s McMichael radio rally will be in this field. Hmm!
Send it any character and the GPIB responds with lots of ASCII 1s and 0s. The pattern is different if the output switch on the front panel is switched between On and Off. I haven't managed to guess the commands to set a voltage or current limit yet. I've tried the obvious characters already.
The third item of test equipment from the rally was this Farnell 30V 2A GPIB programmable PSU for a fiver. Earlier tests showed the output was hunting around a bit when lightly loaded, this turned out to be a missing sense line shorting strap on the back panel. Just needs feet and to figure out GPIB commands. Do you know them?
I got it working! I wasn’t expecting to, particularly after a silly accident this morning that saw me toast many of the parts I had just fitted.to the RF amplifier. Definitely need to dim the green LEDs! 2f is better than specification.
