Does anyone have "in-the-weeds" information on the DECtape read/write
heads? I've got several TU-55 transports and a box of DECtapes (thank you
very much Doug!) _and_ Michael's failed DECtape head from several years ago
that I'm de-potting. I very much want to figure out how to repair
Michael's DECTape head and will return it to him if I can do so.
I've read the document that Al posted a link to in the discussion on DF32s:
Message-ID: <1e97981e-05d9-f272-d2fe-10ae38da6668 at bitsavers.org>
...
"remided me of the problems with rhodium plating on RF08 drives here on
page 9

"
The "Oral History of Grant Saviers" is interesting and gives a lot of
information about various storage technologies that were used over the
years. It reminded me of my desire to learn everything I can about DECtape
_and_ DECtape transports.
Maybe the CHM or someone else has interviews or tech data that helps answer
my request?

Gary,
I don't know if you're in Europe or elsewhere. I'm in the Netherlands, and I could do that free of charge. I'd also make a video recording of the process for your sons education.

Subject: Need to have a roll of paper punch tape read by a tape reader and printed
Hi folks. I wrote a basketball program in Basic over 40 years ago in high school. I printed the 13 pages of code, and produced a roll of paper punch tape of the code, but the 13 pages were destroyed, leaving me with only the paper tape. My 14-year-old son was pretty fascinated to see the roll of computer punch tape -- paper with holes in it! -- that we used to store files in the old days. And that we didn't have computer screens, but only a teletype element that printed -- one letter at a time -- the back-and-forth information between the timeshare computer and the teletype (output). This paper punch tape is the Basic program that I wrote in high school that played a random basketball game (as called by Bill Schonely, radio voice of the Portland Trailblazers). I'm trying to find someone to run it through a tape reader so that I can retrieve the code and play the game again. I'm hoping to explain the code to Owen so that he might understand the power of coding and get interested in coding.
Is there anyone out there that I can send my roll of paper tape to such that the code can be restored? I could pay some compensation for your troubles.
Much appreciated,
Gary

There's a DF32 on Ebay. I've got a bid in on it, will see what happens.
In the unlikely event I win I'll have to build a system to adapt the
Negibus to the pdp8/L. However did the pdp8/L have 3 cycle data break?

FWIW, I went back to the CCTALK archives and could not find the original
message either. Being curious, I went back to the CCTALK archives and
there it was.

Hello,
Someone sent me these magtape images from Tymshare and said "they fell
off the back of a truck on route 62 in Hudson, MASS." I don't know
their provenance.
Sorry, I don't have any good hosting. For now they are here:
https://gitlab.com/larsbrinkhoff/tymshare
The download.sh script will retrieve individual files one by one rather
than cloning the repository; next use cat.sh to get the .tape.bz2 files.
The tape format is close to not not quite FAILSAFE. With help from Joe
Smith, I made a tool to extract the files:
