Sorry, looking at some DIY PPT ideas on Youtube that's not exactly what we're looking for; I was thinking of projects that mount a cash register tape or similar on a lathe or something rotating and then cut it into thinner strips, preferably with a rotating cutter but a box cutter will do. I'm sure they're out there, I've seen them.
I worked with PPT a lot back in my association with Burroughs; the 'L' series of machines used punch-once, read-many mylar tapes in an integrated reader, originally read with pins linked to the electro-mechanical keyboard with both later replaced with electronic versions. For Data I/O some models also used 'normal' paper tape in an external reader and punch, also capable of punching and reading edge-punched cards; these were later replaced with high-speed cassette drives. ---------- Forwarded message --------- From: Mike Stein <mhs.st...@gmail.com> Date: Sun, Jun 22, 2025 at 8:59 AM Subject: Re: [cctalk] Re: Is there a more modern replacement for paper tape punch/reader To: General Discussion: On-Topic and Off-Topic Posts <cctalk@classiccmp.org> Cc: ben <bfranc...@jetnet.ab.ca> Pretty easy to make PPT yourself; Google 'DIY Paper Tape'.
