	I have in my hands a Western Digital hard disk controller, the
reason its in my hands and not in the machine benifiting mankind (well
at least me :-) is because its missing a small (but major) componant.
This missing part is the PROM (I said it was major). This means the
board is brain damaged. With your help I may be able to place this board
back on the road to recovery. If someone could point me in the direction
of a new PROM I'd appreciate it. Here are the Boards vital stats...

It's a WD1002(TAN??) Assembly 61-031092-00 
The prom is situated(piggy back) on the NS87P50D-6 (processor I guess)

This board is part of the hard disk controller for the TRS-80 Mod I, but
the Western Digital part may be standard.
Thanx for you help and support needed in correcting this social outcast.
