	Hmmm - does RT-11 have the ability/utilities to write 512 byte
	records "bits as is" to tape?  No labeling, no nothing.

	Can you, using RT-11 do the equivalent of:

		cat mtboot mtboot boot > file
		dd if=file of=tapedrive bs=512

	Basically what you want to do is have two copies of the tapeboot
	block followed immediately by the boot program written to tape
	using 512 byte records.  Perhaps catenating the data together into
	1 temp file first would help and then write that file out all at
	one time.

	Once you have that data on tape you have a bootable TK50.  The
	other images (mkfs, restor, etc) can be put on separate tapes if
	need be and loaded one at a time.

	That will require some interpolation of the setup/installation
	documents but it shouldn't be too hard to figure out.

	Bletch (to eggs in beer) ;-)

	TK50 tapes are excrutiatingly (sp) time consuming to write - I'm not
	sure where the problem is (other than the TK50 being about as smart
	and fast as a rock).  Reading them isn't too bad, but to write a full
	2.11 kit on TK50 took around 7 hours the last time I did it on a 11/73.

	Drop a line to Warren Toomey (wkt at csadfa.cs.adfa.oz.au).

	Cheers and good luck.
