I have the equipment. It is a 3M tape so it will probably be fine.
It will be digitized on my analog recovery set up and I'll use Len Shustek's readtape program to recover the data.
The only issue right now is my workflow isn't a "while you wait" thing, so I need to pull all the pieces into one physical location and test everything before I tell Penny it's OK to come out.
The whole process is test the condition on a tape retensioner. I'm hoping I don't have to bake it, since that takes a day, then digititze it, shuttle the 10s of gigabytes of samples to another machine to decode it. I want to skip the shuttle step and get the analyzer running on the digitizer.
While cleaning a storage room, our staff found this tape containing #UNIX v4 from Bell Labs, circa 1973
Apparently no other complete copies are known to exist: https://gunkies.org/wiki/UNIX_Fourth_Edition
We have arranged to deliver it to the Computer History Museum
When I got the CoCo, one of the big problems was the super-smeary, snowy video on the RF-out. Even though composite video is generated internally by the video circuitry of the computer, Tandy didn’t end up breaking it out to an actual port. Lots of other 8-bit machines of the era are in the same boat. Luckily, adding a composite video port to the CoCo is very straightforward! So straightforward, in fact, that I did it twice.
