@neauoire the longevity of paper tapes and punch cards is amazing. @phooky and I recovered some from a moldy basement and were able to read them fifty years later. https://trmm.net/Papertapes/
@maxc @neauoire @phooky 8-bit punch tape is possible, although I don't recall if the ASR-33 can send it (my recollection is it is hardwired for 7E2) http://bitsavers.trailing-edge.com/pdf/dec/pdp8/software/DEC-08-NGCC-D_PaperTapeSW.pdf
@th Am i reading it right that it's 2 rows per byte, or is it a bitstream of 6 bits per row (with 7th bit in a row being some section delimiter)?
@maxc that's a weird format since it's PDP-8 with a 12-bit octal word, so two 6-bit rows == 1 word and the 7th punch is used to indicate that the next two rows encode the load address.
@th ah the 12 bit word is the context I was missing :) makes sense now.
@th @neauoire @phooky absolutely love that photo.
Are there standard modern 8 bit binary clean punch formats? Article linked at the top talked about a 7 bit (ascii I guess?) plus parity where 0 and 127 were skipped but seems like there'd be lots of ways to approach it
