Received an experimental version of the reader from John, decided to try out one of the shorter tapes quickly today. POETRY 10 REM POETRY 20 PRINT "IF WE CAN RELATE A SEED OF LIFE," 30 PRINT "TO AN ATOM OF ENERGY," 35 PRINT "......................................" 40 PRINT "MAN TO SPACE"...

I thought about getting a physical machine and programming an Arduino to save the data. But that would be more expensive, and I do not have the mechanical/programming skills/knowledge to make something like that. An other try by John on one of my other tapes, labled "Wizard" It is by far the...

Obviously not, it is only the very beginning of that tape, not the entire program. But it is the beginning... Still experimenting the workflow to get through these, trying things out.

The tapes have arrived. In fair condition. A lot of the plastic rubber bands have turned to goo, some of it even sticky like it melted. But possible to get off without tearing the paper. From the writings on the paper, it appears to be a collection of games, math problems/processing, drivers...

Talking with Johnr about his virtual punched tape reader, it is looking like a really good and interesting solution. I just have to develop a strict and consistent photographing/scanning and stitching workflow so the results will be accurate. Some more info about the tapes from the seller...

Most projects seem to use phototransistors of some kind, an electronic solution. The one from github and the OP-80a replica seem to be the most thought-out and documented. I haven't got any experience with Arduino coding and teletype/altair formats coding so I would need help from the community...

The project at GitHub looks doable. I could probably source the parts, it may take a little while for all of them to get here. May have to order at least 5 PCBs though of each, depending on the printing company. I don't think I will be able to sell the other 4 units that I could make? I...

I have seen emulators, yes. But I need something to read mine. An other option is to take the photographic route, using images of the tape stitched together. http://www.johnr.uk/workshop/computing/vptr/index.html I will try to reach out to John and see if his program can help out here. Not as...

I think for sure more people are interested in running Windows 98/XP-era machines. I am 25 years old now and grew up with the OS, the games, the hardware. A big part of my youth. I assume this is the same way older folk look at big iron, mini computers, MS-DOS. As new generations start feeling...

Is there any new/DIY hardware that can digitize punched tape to a modern digital format? Be it saving the raw 8-bits to a .bin file or saving the program to a .txt file in ASCII. Because I acquired lot of punched tapes from the USA with the intent to digitize, preserve and make the contents...

lets welcome this post to 2019! I have decided to release an unfinished version of the processed data from Pione-QK7992H done by Hans. there are 12 files on the tape, of which we have confirmed 6 to be image files, and have decoded them. There are 3 B/W images and 3 duo-colour images. (file1...

First attempts at merging the blue and red channel from a B/R photo:

Really cool that you worked on NASA tapes before, how did that come to be? and how do the tapes usually end up in the 'wild'? There are many unknowns, but with small steps I believe we can figure this out. I looked around for Kyread, and buying from their website the shipping cost alone is 150...

I got a NASA data reel, and I am looking into getting several more. I am talking with a computer museum about digitizing them. Today I played part of the tape through an AKAI X201D. I did not expect to get any usable data, maybe a faint signal. This is the tape: You can find WAV files and...
