Hi,
I wonder if someone has been succesful repairing the corrupted tpc images of several
PDP-11 layered products that are (not)available in some sites (bitsavers and trailing-edge
come to memory). IIRC there was a kind of effort to fix whatever could be fixed (the BRU
format ones, specifically) reordering the mangled tape blocks in the image.
More specifically, I?m looking for an usable COBOL-81 compiler. The one which is not
corrupted (cobol_v4_4) is COBOL/C11, not COBOL 81, and even for hobbyist stuff, handling
COBOL-74 is a PITA?
Best regards to all.

I wrote a tool that can fix BRU tapes. I can't remember if the Cobol-81
tape is a BRU tape. If it is a DOS-11 tape, then you're in for a lot of
headaches...

Well, cobol_81_v3_1.tpc looks like a BRU tape. Going thru ?strings? it shows:

Looks like a BRU-based autoin install kit to me :)
Moreover, the datatrieve 3.3 tape (datatrive_rsx_v3_3a.tpc) seems to be a BRU tape also? I
have not checked other files. I remember BP2 2.7 is a DOS-11 tape.
Have you make public your fixing tool? If so, I?ll give it a try?

Hi, Jordi.
Yes, that is definitely a BRU tape.
I have published the tool before, and don't mind sharing it again. But I
also already have a good copy of C81, I believe.
You are on HECnet, right? Let me know, and I'll just pass it to you there.
