Thanks to Emanuel Steibler, I am now in possession of a VAXStation 4000
VLC. I've got OpenVMS installed, but, well, the SCSI2SD gives me two more
2GB disks (the fourth partition is the OpenVMS install CD).
I'd like to put Quasijarus on it.
Problem is, the VLC only supports, as far as I know, SCSI devices. I'm
quite happy to install Quasijarus under simhfrom an emulated SCSI tape to
an rz device and then just dd the resulting disk image over to the SD
card...but I can't work out how to do it.
This (as my simh ini file) works fine for getting to the emulated console:
set rz0 rzu
att rz0 quas.dsk
set rz4 tz30
att rz4 quas.tap
boot.cpu
Problem is, quas.tap doesn't actually work; neither the prepackaged
4.3BSD-Quasijarus0c.tap nor one I make with mkdisttap.pl and the input
stand/miniroot/etc files.
I get this:

Sooooo....
How do I make a bootable SCSI tape image from Quasijarus? Or,
alternatively, how can I create a bootable ISO image from the Quasijarus
installation files (and then either install under simh, or just dd to an SD
partition and boot from there, or even burn to an actual CD and install
from a SCSI CD-ROM drive)?
