"Mechanically, the reader is pretty simple β€” just a wooden frame to hold the LEGO Technic wheels used as tape reels, and some rollers to guide the tape through a read head. That bit is custom-made and uses a pair of PCBs, one for LEDs and one for phototransistors. There are nine of each β€” eight data bits plus the index hole β€” and the boards are sandwiched together to guide the paper tape." (from June but still cool) hackaday.com/2024/06/15/homebr…

I have a roll of paper tape from 1975-6, probably has a CS homework assignment in basic.
Don't think I need to relive the experience.
