4.2 standalone uda50 driver bugs

[pag at hao.UUCP]

The standalone UDA50 driver on the TU58 cassette included with 4.2bsd
will not boot from a second UDA50 on a 750.  It works fine with the
first one, however.  The symptoms are:
(cpu switches set to boot from TU58)
>>>B
=boot
Boot
:ra(8,0)vmunix

The cpu then just hangs.  This problem also existed in the normal (not
standalone) 4.1a uda50 driver -- any access of the 2nd uda50 (on UBA1)
just hung.  Driver fixes from Alex White fixed that problem.  I would
appreciate any fixes for this.  Also, since I haven't brought 4.2
up yet, I am curious whether the included uda.c works with 2 UDA50's
on 2 unibuses on a 750.  Anyone know?
