I always wanted to own the Heathkit H-10 Paper Tape Punch./Reader but when I built my first computer, a Heathkit H-8 Microcomputer with a whopping 64K of RAM, audio cassettes were popular for low-cost for data storage and I had to choose whether to build something cool - Paper Tape - or something state-of-the-art - Cassette tape. I chose the latter and was thankful every time it only took me 20 minutes to boot from cassette rather than hours booting from paper tape.
Of course, if I had chosen paper tape, I could still read my data, whereas I doubt of I can still read any of those old cassettes.
Today, I came across an old paper tape punch/reader mechanism that has been sitting in my computer museum for almost 20 years. (It's probably twice as old as that.) I don't remember where it came from of what computer I would have salvaged it from. My best guess is that it may have come from a Teletype terminal similar to a Model 35ASR, but I really do not know.
I'd like to get this working again as an I/O device, but first I will need to reverse engineer the wiring and build an interface controller for it. While I love the challenge of reverse engineering, the task much simpler if I could identify the unit and find a schematic or manual for it. I've decided to blog about this in the hopes that someday someone will Google for Teletype or Paper Tape Punch/Reader or perhaps even a DEC PDP-11 Paper Tape Interface.
Can you help me identify this mechanism?
If you can identify this mechanism and/or provide links to any resources that might help me, that would be great. I'm starting to scour the vintage computer forums as well. I'm sure someone out there has already built an interface to allow you to punch or read paper tape with a modern PC using a parallel port.
Update: After watching some YouTube videos of a Teletype terminal, I've concluded that this mechanism did not come from one of those, It may have been from a stand-alone paper tape punch/reader device.
