Yah, it was 6 bit tape for text preparation, with 8 bit tape used for programming & setup of the phototypesetters. Meant a lot of messing around with the tape readers, since one width of tape expected the feed holes to align with the center of the data holes, and the other width expected the feed holes to align with the leading edge of the data holes.
Speaking of Flexowriters, we had one of those for doing commercial mass mailings that looked typewritten - I still have one of the 576 bit core memories it used. Each memory board was about 8X11 inches. The individuals cores are really big on these boards.
Good times...when you weren't dozens of levels removed from the actual physic of computation.

That was probably 6 bit tape -- most typesetters I've seen that were fed with tape used 6 bit tape.
My first programs were written on paper tape -- Flexowriter editing papertape typewriter/reader/punch machines, with a character set optimized for Algol 60. That was at the Technical University Eindhoven, then known as THE -- which is where the operating system by that name came from. It was a batch system: paper tape in, line printer output. Magnetic tapes available in theory but rarely used, plus a drum for paging. Processor was a Philips (Electrologica) EL-X8, a 27 bit machine with a rather exotic I/O architecture that I never really understood.
BTW, Flexowriters are great machines. Teletype Corporation never built anything remotely as reliable as those -- certainly not the cruft known as Model 33, and even a Model 35 isn't as good.
Semaphores (in the computer science sense) were invented there.

Oh good heavens. Same sentiment...and used in exactly that way since well before either of us were born.

Subject: [HECnet] punched tape
Hi folks,
I've got a crazy idea, so please humour me...
Does anyone have a length of punched tape they could send me? Ideally tape
that is five bit, which is 11/16 inch wide I believe.
I'm presuming that there is nowhere to obtain paper tape anymore?
Thanks, Mark.
I have some paper tape that came with ASR33 Teletype I got a while ago, but
that tape is wider and I have momentarily mislaid it. Let me know if it
would help. How much would you want?
Regards
Rob

Amen. Yep all generations of CS students should read the paper: http://www.cs.utexas.edu/users/EWD/transcriptions/EWD01xx/EWD196.html
is a transcription. It's the first use of "rings" or "levels" that DC would implement later for VMS.

Not at a job, but the first "real" computer I put my hands on was a Motorola EXORCiser, with a TTY attached (no CRT) when I was at High School. The only way I had to "save" programs was paper tape. Eventually I got a nice 8 inch floppy, but I was using paper tape for a while.
Similar story here, but with a PDP-8/e. It had DECtape (TU56) and paper
tape. I still have the system.
