From Lou Ernst, 10/23/2011 - 

Gentlemen,
 
      Attached are the files dumped from a number of TU60 cassettes that Jack Rubin had found. The cassettes included:
 
 -  a bootable cassette: DEC-11-OTSYA-A-TC
 -  two cassettes of assembled object files: DEC-11-OTOBA-A-TC1 and DEC-11-OTOBA-A-TC2
 -  ten cassettes of the sources: DEC-11-OTSRA-A-TA1 through DEC-11-OTSRA-A-TA10
 -  three cassettes related to TADP: MAINDEC-11-DZZCQ-A1-TB, MAINDEC-11-DZZCQ-C-TB, MAINDEC-11-DZZDH-B-TB
 
       I was able to recover all the contents on my TU60. I copied the files off to RL02 under RT11 V4 on my 11/04. The bootable cassette indeed works as I was able to copy it and boot it. A hardware switch register is required.
 
       The documentation (manuals) are still missing. It would be very useful if they would turn up. At least we have the sources.
 
       Chris Rau scanned the MAINDEC-11-DZTAF-C-D diagostic write-up from fiche. This is not currently on bitsavers. It contains the TA11 toggle-in bootstrap. The version I have is 11MB. I will send it to Al under separate cover.
