Nop - or better partly correct - it is true that not every punch
combination was legel (that would be 4096 possible) but at least
there was a legal combination for any possible 8-Bit combination.
Otherways I would have been impossible to boot from a punch card
reader !

I love your comments (and I guess you had also some contact with
these 9 Bit Byte Bull Mini computers :)
