It should work through an ACTIVE adapter after programmed. It won't work with those dumb purple/green ones.
I'm using a PS2 to USB adaptor with both a unicomp (was a gift, they got PS2 by mistake) and a WASD through an adapter at once (saves a USB port).
It's not "hard" to find a computer with a PS2 port, I have 4 in my room, just none have windows on them (and only a few technically "work") I'm going to just shut down my windows box and swap the HDD over into one of them and borrow a monitor for the programming
I just had to unplug and the replug the adapter from the USB port, no idea why, but it works now.
I like how "cancel" maps as [ and there is a key labelled with period and semicolon. (comes out as "v" and "V" in Dvorak). "clear" seems to be backspace.
