Hi,
I’m trying to boot
http://bitsavers.trailing-edge.com/bits/DEC/vax/vms/BB-D782B-BE__VMS_V1.5_1600.zip,
mostly for interest’s sake. I presume this is an installation tape of some
sort.
I’ve tried on the VaxSserver 3900 simulator, but always seem to get a
“DevOffline,” message for Mua0:, the magnetic tape reader.
I was wondering if I might have better luck with the VAX 11/780. I don’t
actually have real hardware of any kind. The reason I was asking about console
floppies is that, as far as I know, I can’t directly boot from tape on the 780,
at least not with the SIMH “boot,” command.
If this is something other than an installation tape, of course, the whole
process isn’t worth the trouble :)
This is indeed an installation tape. I used it to buiild my VAX-11/780
installation on Raspberry Pi. See
http://vxcompany.com/kennis/blog/2016/01/22/a-working-vax-11780-revisited/
The VMS version it contains will never run on a 3900, which is way newer
than the 780.
So make sure your get the latest simh sources from github, and build
yourself a "vax780" model. Read vax780.doc, then configure it with (for
example) an RP07 disk and a TE16 tape unit, restore the tape (find the
AA-D021B-TE VAX-11 Installation Guide on bitsavers) and start playing...
