Sorry not to have been clearer. I'm usuing PS2 keyboards (IBM M5
keyboards is all I have). My new box lacks a PS2 port and so I had to
get av PS2-USB adapter. It worked. It has been woking for for
about half a year.

However, this morhing I found I lacked keyboard input. When I pulled
the keyboard and apdapter the adapter fell apart. I tried
another PS2-USB adapter, but a different brand from the one that fell
apart, and it did't work.

Someone suggested a possible adappter-keyboard incompatibility, and so
I tried the same brand adaptaer as my original one. This works, but
only in a USB port other than the one I was orignally using. So I'm
back in business, but perhaps with a non-functioning USB port.
