Re: Update: Apple Game Server

I was trying to leave the stack completely alone if at all possible.
Since I'm about to replace rwts with a modified version of this I want
it to run very lean.  The only reason the read/write serial functions
are subroutines is because of their frequent use (so to keep size down)
and so they can be reimplemented more easily should someone be using a
different slot or a different card that uses an alternate I/O mapping
to memory.
