I learned at VCF East this year that I should have brought an UPS to
make sure that my vintage equipment had good, clean AC power. My PDP11

I hadn't started this DEC Alpha 3000-300 since last summer, and booted
it up so I could load the new PAK's the other day.
The result was that it completes almost the entire OpenVMS startup, but
then crashes with the following:

It has a date code of 1989 and was built in Yokahama Japan, by who I

Does anyone know who DEC had build there CRT monitors back then? Are

I've used the SCSI2SD with great success with vintage DEC computers.
On QBUS machines, both vax and pdp-11, it has worked with Emulex UC07,
TD systems Viking, Andromeda SCDC and the DEC RQZX1 controllers.
I have used it on native SCSI controllers in VAX 3100, VLC 4000 and 64
bit ALPHA machines.
