Hi
The great TK revival continues apace.
There's a TK50 in my VAX 4000 running really well. Purrs like a cat
I have TK70 in the RT-11 (11/83 QED) Machine that also runs.
TK70 should read the TK50 tapes. It tries but complains about cant read
the directory.
So whats a common format I can write on a TK50 tape in a TK50 Drive (VMS)
then take it over to the RT-11 box and have it read it.?
Where is all this going? Well I need to end up with RSTS on an 11/83.
So a bootable TK50 with RSTS install files on it is the goal.
Meanwhile transfer by tape is useful.

Another method of checking any data on any physical device
is to use the RT-11 program, DUMP.SAV, which will display
the individual blocks in the case of a disk drive and the individual
records in the case of a tape.
Unfortunately, my PDP-11 hardware is not available right now.
But I was able to use Ersatz-11 to perform the same operations.
Under RT-11:
INIT MU0:/NOQU
DUMP/TERM MU0:
Three 80 byte records and 4 tape marks are displayed as in:
First 80 byte record
Second 80 byte record
TAPE MARK
TAPE MARK
Third 80 byte record
TAPE MARK
TAPE MARK
If you can display the above data when you INIT the TK70
media on the PDP-11/83 under RT-11, but can't read a TK50
media produced under VMS, then perhaps there may be a hardware
problem.
Let us know what you are able to see. Then we can help some more.

I'm now at a TK70 drive (and controller) both ends
It looks like both drives and controllers work on both systems.
The VAX end reads TK50 tapes and directories.
The 11/83 (QED) system end does not.
I'm off to look at VMS exchange with a view to producing something the
RT-11 end can read,.
I'm sure there's an RT-11 TCP/IP around I have enough parts to extend
the network from three PC's plus
four vaxes and an alpha by adding:
11/23, 11/53, 11/73, 11/83 (QED) , 11/84 and 11/94
By using Decmates and Rainbows as terminals they all get a console.
