I had the fortune of recently finding a Northgate OmniMac Ultra keyboard (The Mac variant of the OmniKey Ultra) for $5 at a thrift shop. However I've had no luck getting it to work, or even light up for that matter. I really don't want to have to scrap this thing for parts, so I'm hoping someone around here might be able to give me some insight into what the problem is that I'm having. I've tried using straight PS/2 to PS/2, as well as PS/2 with a converter to USB. Neither of which worked. I have a teensy and the resources to mod this thing, but before I do I want to make sure it's actually kaput.
What I'm thinking may or may not be the problem:
1. Is now fried potato. I've been reading a little bit about ADB (Apple Desktop Bus), and I've heard vague references here an there to hot-swapping being dangerous, and an explicit instance of an OmniMac or some other old keyboard being fried after plugging it into an Apple II or something. IDK. Either way, this might be what happened.
2. My dip switch configuration is incorrect. While I've been able to find OmniKey Ultra user manuals, I haven't been able to find any specific to the OmniMac. My assumption was that the only difference between the OmniMac and the OmniKey was the inclusion of ADB ports on the back. However, my inability to use the PS/2 port on the back makes me think the dip switch configurations might be different.
3. Are OmniMac ultra's actually (by default) compatible with modern machines? I assume they are, but I'm unsure seeing as there's very few resources I've found for properly configuring one of these things
Anyway, please share your thoughts on what I might do here. I would really like to use this keyboard.

edit:
What I'm primarily looking for now is if anyone has had any experience with this keyboard or a similar one and actually knows how to configure the dip switches. Or if anyone can confirm that the PS/2 port is actually intended for what we're assuming it's intended for here. Or just a goddamn manual
