[aclug-L] Re: Aclug COOP Cluster?

[Jonathan Hall <jonhall@xxxxxxxxxxxx>]

I've go t a few 40mb HDs that could be used for swap.  I've also got a bunch
of 360k floppy drives that could be used to initiate a net boot (rather than
using (E)EPROMs), and 360k floppies are easier to replace/change, altho
they're also more likely to stop working... :-)

If/when you're ready to actually set this up, I'm happy to (schedule
permitting) come help.  I've done a bit of playing with diskless
workstations and netbooting... some experience that might come in handy.
