@betajet: Yes indeed, a magic spell called DEC RADIX-50 which encoded 26 upper-case letters plus 10 digits plus a few punctuation marks into a number from 0-39, and then multiplied the first character by 1600, the second by 40, the third by 1, and added them all up. So why "RADIX-50" instead of 40? Well, we PDP-11 dudes always preferred thinking in octal :-)
I remember RADIX-50 -- we used to use it on little GENRAD PCB functional testers (I think they were the 2225 testers) -- I thought the whole concept of RADIC-50 was absolutely brilliant.
@maxthemagnificent Be there or be square! Love to chat on the chat about whether we should bring back the name "Embedded Systems Conference?" After all, teenagers are wearing old spice these days so retro is in!
