Hello all,

I have transferred some simh .tap files to my PDP-11/23+ running RSX11M+.
There I have tried to use VCP to attach them to a virtual device but I
keep
getting an invalid record format error. I then realized the simh .tap
files
most likely aren't organized correctly. If I attach them to TS0 in simh I
can work with them. So now I am trying duplicate a tape into a new .tap
file created using VCP. I can't for the life of me get it to work though.
BRU doesn't support tape-to-tape and FLX doesn't complain but also never
completes. Is there a process for tape duplication under RSX?
I wrote some stand-alone programs that did mag tape copies,
and directory listings in Fortran on RSX-11M and VMS.

I could send you these if you have Fortran on your system.

Hi Jon,
That is part of my dilemma, I am trying to install Fortran among others.
But being a physical machine, the SIMH images aren't working.
I'd still be interested in the programs though if you don't mind sharing.

Well, actually, I have an RSX-11M executable of the program.  I don't know if that would run on an RSX-11M+ OS, but it seems like maybe it would.  It might require byte-hacking the tape drive unit addresses.

Let me know if you want to try this.  I have placed a zip file named magtape.zip on my server at:

http://pico-systems.com/codes/magtape.zip

Let me know if you have any problems with this.

Jon
