Install tapes for V9 or later are weird constructs; they are partly DOS and partly ANSI format.  I don't remember the messy details.

If you have a TAP image of a good installation tape, the best answer is to copy that to the physical tape, because then it will definitely work.  Trying to construct one out of pieces isn't as easy.

If you have a way to make TK50 tapes from TAP images, then I'd suggest this:

1. Make a TK50 install tape from a TAP image of a known good install tape.  Remember that installation tapes have to be write locked when you boot them to be recognized as an install tape.

2. Do just the first steps of the install, just what's needed to copy the sysgen environment to the disk.

3. Do a full backup of your SIMH setup to tape (TAP image), with the Backup command.  That will create a simple tape, nothing nearly as strange as a kit tape.  Then copy that image to another TK50.

4. Put the backup TK50 into your 11/83 system and do a full restore.

5. Reboot and use the INSTALL command in Init to select the regular system SIL that you copied in step 4.  Proceed with startup; you should now be all set.
