I ended up with a small pile of brand new HP keyboards and mice and unfortunate for me they are all ps2. I was looking to buy ps2->usb adapters but since they are passive adapters they will possibly not work.
I know the ps2 optical mice I have will not convert correctly on a passive adapter. The keyboard is what I am unsure about. Despite my best efforts I cannot find any documentation for the thing on HP's site. Even when you select the original computer that this gear came with there is no appendix documentation provided that covers the keyboard specifically.
So I was hoping someone else out there that uses these might know and can save me from possibly buying adapters I can't use. Thanks for reading.
