VaxStation 2000 and TK-50Zs

Hi Don and other ListErs,

I have been working on a similiar problem... I have the original DEC
distributions for a few things (including Ultrix 3.1, looking for
UWS 3.0), and I want to make archival copies of them...

I discovered the TK-50Z (both FA and GA) will work with FreeBSD and
an old Adaptec SCSI controller. This allows me to read (and copy) the
TK50 onto my PCs hard disk, but I haven't quite got the format right
to write a new tape (still playing with file marks)...

NOTE: I tried a 2940 and a 1535 and neither of them worked. I was
successful with a AHA-1542B scsi adapter.

I also have a SCSI adapter for my uVAX II, and have copied tapes
from TK50 to 4mm DAT, but it seems quite a waste to put 95MB on a
4GB tape.

Finally, if none of these options appeal to you (and you don't
have other success), I have a uVAX II with a TK70, TK50, SCSI
adapter for the 4mm DAT, and a 9-track tape drive, and can copy
them for you (contact me off list for this).

Laters,
clint

PS My 11/750 is up and running!!! The dead power supply turned out
to be two pins shorted on the backplane... Sometimes my debugging
skills leave something to be desired...

PPS What is a Fujitsu Eagle worth used? I am going to upgrade the
11/750 to a SCSI controller and 3.5" drive as soon as I get two
nickles to rub together :)
