Dear forum members,
I am a dutch space memorabilia collecting enthusiast, especially when it comes to digital and analog tapes.
Last year I have been busy digitizing NASA magnetic tapes. I buy the tapes myself and then look for people who can read them. Most of the tapes are 7 and 9-track computer tapes, digitized by Chuck in America. There are many people who help, and everyone does it on a voluntary basis. Without the help of others we would never have come this far.
So for a new project, I need YOUR help.
First an introduction to a number of ongoing projects:
See here a computer tape used for Apollo 16 in one of our drives:
A sample of the data:
After some research we suspect this tape was used to diagnose the Saturn-V after it was assembled at the VAB. With a computer at Launch Control.
Another project was with magnetic tapes with Pioneer 11 space probe data. The American has been able to read most of the tapes, and from 1 we have now converted photographic data to PNGs:
Three B/W photos from the tape:
1 of the 3 color photos:
So we have already saved and processed data from two projects. These projects are still running, but are on hold because we are waiting for documents from NASA.
The current digitized data can be found here: https://archive.org/details/SpaceData
Furthermore, I have digitized hours of Apollo broadcasts recorded on 1/4 inch tape recorder tapes. In Dutch, German and English.
These can be found here:https://archive.org/details/thirdpartyaudiotapes
For this I have an Akai X-201D and Revox A-77 IV
I have also digitized NASA S-VHS tapes, and uploaded some tape recordings of the Apollo missions. See links below:

Nice, but what do you want now?
Since last week I have bought 4 NASA tapes from Ebay. It is 1/2 inch tape on a 10.5 inch reel and has 7 tracks. The tapes are recorded with Ampex FR-100 and Ampex FR-600 instrumental recorders. On the tapes are analog telemetry signals from satellites, recorded at NASA stations in 1963.
It seems that there are 6 telemetry tracks, and 1 voice track.
I do not have have Ampex FR-100 or FR-600, and they are very scarce. Nor do I have a 1/2 inch 8-track recorder.
What now? There are 8-track 1/2 sound recorders. The height difference between 8 and 7-track is so small, I think you can play a 7-track tape on an 8-track recorder.
If you adjust the 8-track head up and down, to align it with 1 track at a time I think we can pick up a good signal. I have talked with someone, and he says the tracks are just analog waveforms. I once played a 9-track 1/2 tape on a 1/4 4-track recorder, and I received an unusable but stable signal.
I and others would really appreciate it if someone makes his (Or hers!) 8-track 1/2 inch recorder available. The tapes will have to be shipped from the Netherlands. For this to work, the head must be adjustable.
It would be best to use an Ampex FR-100 and FR-600, but I think it's unlikely that we will encounter them.
If you have any questions, I gladly answer them!
I can finance material and time where necessary.
And if you got any NASA related tapes yourself, I will gladly work out a way to have them digitized! so let me know if you got any.
Happy Holidays,
Niels
