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
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.
