[Simh] Largest VAX / PDP disk sizes

Sat Mar 27 17:07:02 EDT 2010

Ok, I replaced the 'ra72' with my guessed 'ra73'....  I just mounted the
miniroot on a rq1 (as a ra81 it doesn't matter)

% cat x.ini
set rq0 ra73
att rq0 ra73.disk
set rq1 ra81
att rq1 mini
set rq2 dis
set rq3 dis
% ./vax x.ini

this would be about right, right?

Also disklabel on NetBSD said this about making a disklabel....

disk: RA73
label:
flags:
bytes/sector: 512
sectors/track: 70
tracks/cylinder: 21
sectors/cylinder: 1470
cylinders: 2667
total sectors: 3920490
rpm: 3600
interleave: 1
trackskew: 0
cylinderskew: 0
headswitch: 1           # microseconds
track-to-track seek: 0  # microseconds
drivedata: 0

Oh well FWIW it seems easy enough to stomp an existing drive, and
rebuilding.......
