spoiled by megabytes of memory

[jon@i-manila.com (Jon Co)]

Ive just finished writing that prodos clock driver (to which nobody
reacted to so I presumed no one is interested) And I realize
something, We have been spoiled by modern-day megabyte-size memory
systems.  Back in the old days, every single byte counts.  Prodos date
and time was stored in a rediculous (according to beagle bros manual
of big-u) 4 byte format just to save 1 byte and make it really hard
for programmers to encode/decode it.  The clock driver itself needed
to fit in $79 bytes or so.  My first try used up a page, after several
days of compression and adding subroutines I finally got it.
