[SunRescue] Hardware reference re-structuring ideas.

Wed Jan 5 20:26:03 CST 2000

I would also suggest having the document in a PDF format ( with all the
indexes and cross references in the way Chris describes) this would make 
the document easy to use as a off-line document. Also a section on the
more exotic cards sush as the 'DGM&S V35 cards' and so on would be good 
for reference...plus someone should try and obtain more hardware
documentation for the more offbeat cards..before they are lost for ever.
Also what would be a nice aldo a bit of a task to produce is a archive of
all the sun os software that was produced. e.i sunos 3.0, 3.5 etc. or
references to it..for the serious collector of sun equipment so that ones
a sun machine becomes decommissioned for the last time it could be
restored in its original form just for historical reasons...that's why I
kept all the old 105 MB and 200 MB hard discs. To one day reinstall the
systems in their original glory.
