Thanks for giving it a go, did you get a reply ?

I have successfully downloaded RT-11 v5.3 from the net
and I can sysgen it for DU and DL devices - no support
for the DELUA, sadly - I think that might have been
included in the DECNET disk which was offered separately.
I have the DECNET disk on an RL01, but the kermit
I have doesn't support fetching the disk image - at
least via "get DL0:". So I can't get a copy of DECNET
into the emulator.

I have sysgen'd OK in the emulator, but I now have the problem
of getting the resulting file out of the emulator and into
the '11. The emulator writes to a single binary file in Linux,
which is an image of a whole disk.

I don't know whether my version of kermit-11
will write to the raw device DL1: a bloke on the net
reckons this is possible, but I haven't tried it ... it is a big step to
take because it means overwriting a whole platter, and
I don't have (m)any to spare.

Also, another problem has appeared - out of 3 RL01 drives,
only one is working at the moment. I can't figure out
what is wrong with the other ones, but it's going to make
transferring this file system somewhat difficult.
I'd have to boot from a working RL01 with an O/S and kermit
and overwrite both the O/S and kermit with the new version
of the O/S.

I tool the DELUA out of the system to see whether it was
interfering with RL-11 (RL01 controller) and somehow causing
a disk problem, but it didn't make any difference. I'm going
to look at RSX-11 to see whather that will support the DELUA,
if not then at worst I might have to look for a DEUNA. The
various comms manuals contain dire warnings about the earlier
-11s not being able to keep up with the DELUA anyway.

If you have the time sometime to come over and read the RL01
circuits for me then that would be very helpful.

(Of course, the ideal way to go would be to get a pair
of RL02's but of course they're rarer than hen's teeth).
