All,
	I spent some time last night adding stuff to my virtual tape server.
I have to test it today, but essentially:


	Box with	serial line		PDP-11 with
	tape server	----------->		uncompress & dd
	+ disk_image.Z				(bootable)

In other words, you can boot to an uncompressing dd, and suck over
any disk image, without actually requiring an operating system.

With this approach, you obtain an existing disk image that will work,
or you use one of the PDP-11 emulators to create a disk image with a
Unix kernel configured for your system. You then compress it, and
suck/splat it to your real PDP-11 via the serial line.

Now, what I've currently got will cope with -b12 compressed files. Can
someone tell me if it would be feasible to fit a gunzip into 64K?? Even
if it could only cope with gzip -1 files.

Cheers all,

	Warren
