I am now up and running using an Emerald XNX 60-9000 tape drive using
Xenix 2.3.1.  The tape drive operates quite nicely - as nice as it did
under 2.2 using Emeralds' tape driver.  But I guess that it will take
a while to dump 250Mb no matter what it is being dumped to...

Earlier I reported that I was having trouble configuring the tape
driver in Xenix - turned out that I was reading the manual instead
of the screen.  The mkdev command displays instructions to enter the
tape controller I/O port in the form ####h (masm-ish) and the manual
lists all lof the default I/O ports in the form 0x#### (c-ish).  I
kept entering the I/O port in the c-ish form - rather stupid of me...
Anyway, after a bit of time on the phone with an SCO support person
I got straightened out if not a bit embarrassed.
