UNIDISK 3.5 800K DRIVE: metal shield

[buggie@ben07.unm.edu (stephen e buggie)]

       I have successfully repaired the 65C02 processor chip in two
Unidisk 3.5" drives!  They were junk before, but now they WORK!

But I added a socket for the 40-pin processor, and this increases the
vertical height to such an extent that the metal shielding wont fit.
The drive casings are held together now by DUCT TAPE ---- looks bad, but
works okay.

Am considering for the next repair on a Unidisk 3.5, to cut the center out
of the metal shielding cap, so that the case can be reassembled with the
corner screws being used --- eliminating the duct tape.

But is the metal shielding very vital?   The drive works fine when
operated as a naked unit outside the housing.   How serious is RF
interference on radios in the house???

Thanks,  Steve Buggie
