i have a Unicomp ps2 keyboard that I’ve been using for about 25 years that seems to be nearing the end of its service life. it gave me a scare a few years back so i bought a cherry mx board as a backup but the thing gave me doublestrikes all the time so that’s not a long-term solution for my next iteration. considering going for another unicomp since i like the chonkyness of it. i always think about a keyboard i encountered back in the 90s that had a special MACRO section onboard, and the old SIIG ALPS keyswitch keyboards. anyone used one of those new-fangled optical keyswitch boards?
The lag is unfortunate on the USB version. They’re already loud and fairly high activation force; when you add in the latency, the experience of them is pretty different than sitting down in front of a real IBM Model M and a DOS machine (with PS2); like they are far more dramatic than they really are.
It took me a year or so so using the USB version (and occasionally going back and trying them again and again because I like the key feel) before I decided the latency was too much for me.
My memory of the PS2 versions is they have no lag whatsoever. If you have a computer with PS2 you can try it; or you can try a PS2->USB converter, as well. I bet different converters have better latency than the stock electronics.
