  Back in the old days, a friend and I made some headway in disassembling
the Zork interpreter.  If I recall correctly, they used 5 bits per char.
for encoding text.  Only 32 combinations you say?  Well, the first 26
were the lower case alphabet, and the other 6 were for switching character
sets.  That is, one would switch to upper case, another to punctuation type
stuff, etc.  I don't remember the specifics though, sorry.
