I believe this is the first way I will use it also. Especially to access
my PC/SGI disks from the MuP21 and the PCMCIA disk I'm buyng (NOTEWORTHY
PCMCIA 105MB HD NWHD105M3 A952995 $285.00 N @ Sparco.com) -- from the
PC/SGI.

Most naturally, everybody likes its version of the wheel best (I'll be
porting my version too :-)

The software will have some necessary functions, especially in the beginning,
when you don't have anything on the MuP21. Later you may safely throw it
away. But it will necessarily contain some useful examples, which may well
save you days. So it will be woth buying, or at least I think so.

This is the most feasible link, I believe. Even (some) SGIs at work have
parallel ports.

Lucky you! My coral island will be Bulgaria in the middle of a fierce
pre-election preriod. This won't prevent me from using the ski runs, I hope
:-)

Since I don't have a notebook, and don't think of buying one just for the
project, I'll rely on what's available on-site.
BTW, if you won't use the video, you may put a slower xtal for the memory
refresh and not kill the MMU with frequent off-page accesses. How slower --
this is a question to Jeff.
