   I haven't tried it but that's not what HP says.

   Yes, you have to match the dot(s) on the cable connector with the dot(s)
on the socket.

  I think there is an addressing limitation but HP says that you'll usually
run into the power limitation first. I'm not sure how you're supposed to
know when you do unless the whole system chokes.

   I don't know. I would think it would work with Windows BUT I was told
that DrawPerfect was the only program that used the mouse. I tried the
rodent on my 150-II with several other programs and none of them (including
PAM) used it. I have MS Windows for the 150 but one of the disks is bad so
I haven't been able to install it.

  Yes, but not the standard 150. The TS-II uses the HP_HIL devices, the 150
uses a non-standard keyboard.
