PS/2 to USB adapter
u_rebelscum:
There are two types of ps/2 -> USB adapters. One type works fine, the other sucks, but which type you can use depends on your encoder.
The type that works fine is "passive"; all it does is a simple pin/shape rewire, and relies on the encoder to be able to tell it's hooked to a USB vs a ps/2 and be able to send the matching protocol.
The type that sucks is for encoders that can't tell the difference, and thus has to translate the ps/2 protocol to the USB protocol. Since the adapter is actively doing the translation and are designed for normal keyboard use, there are (usually) many limitations: number of buttons pressed at a time is very low, duration a button can be held down is short, etc. The hotrod encoder is an example of encoders that only talk ps/2, so they suck at usb even with an adapter.
I don't know if the hagstrom KE72 can speek usb or not. If it can't, then you're out of luck. :(

I bought it years ago when I first got the arcade building bug. I bought a ton of odds and ends, but then when I started cutting the pieces for the cab I lost interest in finishing it.
I got the bug again now that a light gun is doable but I promised myself I wouldn't buy any more parts until I actually use what I got.
I paid over $100 for this encoder, back when I didn't have $100 to spend. When I'm done there's going to be a pile of unused parts, but this encoder isn't going to be one of them.
This weekend I'll try and get a passive adaptor and test the encoder with my office computer.
(I guess I should have done that in the first place, but the voices in my head wanted me to buy an arcade computer this week)
