have you ever seen an ascii chart meant to be carried in your wallet?
@astrid omg i should recreate that in an svg
@chfour please do!
@astrid do you happen to have better pictures of it? does someone recognize the typefaces used? that'd help a lot
@astrid the title on the back i think is just helvetica bold condensed
@astrid struck gold! here's a whole bunch of those https://www.rtty.com/CODECARD/codecrd1.htm
Teletype Code Cards

@chfour @astrid

Dad used to have the Canadian Pacific Canadian National card!

His office had about a dozen telex machines pretty much constantly spitting out stuff.
Between ringing phones, telex machines and the typewriters, it was a noisy place.

@chfour @astrid it's more likely to be Futura or one of its contemporary ripoffs. I'll have a good look when I've got a moment, it's a gorgeous work of art!
@chfour @astrid Unfortunately, the scans are too low resolution to get a proper id on the fonts. I can exclude Helvetica though (The "R" is a dead giveaway). The header font is different from the fonts in the table, the callouts and the ruler. Given the period, it may well have been composed using dry transfer lettering with whatever font was available. The sans serifs are probably two of the many American gothic typefaces of the time.
@astrid the 21st century version of a pocket constitution
@astrid but - but - it says right there it's not ASCII, it's ASPTCII
@astrid I used to have an RS232 card in my wallet.
@astrid one of the hobby computer magazines in the UK gave away little reference cards for a few months in the very early 80’s. They included such gems as the pinout and signal timings for a parallel printer port, and separately, RS-232. Postcard sized, mind, not business card.
@astrid of course you carried that card in your wallet. for emergencies. you never know when you'll encounter EBCDIC :-P
@astrid my big wallet still has one. Honeywell serial terminal on the back.

@astrid

If you flip it over, does it have EBCDIC?

#EBCDIC #ASCII #encoding

@astrid @futurebird Not in my wallet, but I did indeed used to carry an ascii chart with me.
