So I usually avoid "tech support". The last time I had to (mobile
hotspot) I got people with strong Indian accents who ignored 90% of what
I said, seemed to know very little about the product, and gave no
helpful advice. Then I'd be cut off, or (a couple of times switched to
Sprint). The Sprint person was easy to talk to but this is not a Sprint
Well, I had to hook 2 computers to the same monitor and
keyboard/mouse at a clients yesterday - only had a ps2 KVM and only
one computer had ps2 connections. I connected the ps2 mouse and
keyboard to the KVM, and the kvm to the computer with PS2 ports,
started it, then connected the kvm to the new computer with ps2/usb
adapter plugs (the little purple and green adpters that used to come
with kbds and mice), switched it to the second position, and started
the second computer - no problem. Switches back and forth perfectly.
So it CAN work.
I doubt that they know what they're talking about.
You're unlikely to find a PS/2 card. Even the PCI card was probably a
PCI to USB chip and a USB to PS/2 chip.
The PS/2 ports were in the 8042 keyboard controller on the motherboard
(and the 8042 was usually inside the SuperI/O chip) and used IRQ1 and
12. You can't do an exact legacy PS/2 port on PCI or USB, just as you
can't do an exact legacy serial or parallel port. But the KVM shouldn't
care about any of this.
Since USB to PS2 adapters are so cheap you might as well try one.
I do not think I have seen a direct answer, yet. Does either machine
have native USB and if so, does it have both front and rear ports?
The units with front ports usually have motherboard headers that one
may repurpose and/or adapt. Make and "model" of your PC's would be of
more help. However, if you do not have native USB then you are in the
card hunt. I imagine that they are still available, someplace.
