It is a Twiddler one. So it has an AT or PS/2 (doesn't matter, electrically
the same), which is for 5v power for the device. Then the actual data goes
back and forth via a 9 pin din serial connection.

So he could use the USB to PS/2 adapter to provide power, then a USB to
serial adapter like:

http://www.pfranc.com/usb/usb.shtml

to provide the data conduit.

If it was a twiddler 2 then he would just need the USB to PS/2 adapter and
that is all.

Just a little confusion I assume as the T2 has been out forever and the T1
was only around for a little bit.
