Nothing wrong with 'run what you got'...

But... All our 1970's vintage S-100 gear save 3 8" FDD was shipped off this 
summer to a collector, the 6' magnalium-alloy US Navy surplus rack, power 
supplies, Sperry ISS-80 'absolute' air filter system, all went to the metals 

For production we 'downgraded' all our 1U rackmounts save one to VIA C3 from 1.X 
GHz Celerons (FreeBSD 4.11) to help stay within the Data Centre UPS power budget 
for our rack, and upgraded the 2U rackmounts to Tyan MB with Intel Core-D and 
FreeBSD 6.2/AMD-64 OS.

But I *still* say it is 'not kind' to the DFLY project - already struggling with 
  scant resources and tough goals, to distract or sidetrack it even a little bit 
to chase aging hardware flakiness - especially when there are other usable OS 
that can make good use of that hardware w/o any work.

Let's keep out of the core DFLY team's way so they can get the basics done, 
demo'ed, and publicized FIRST.

IF THEN more folks take an interest and come on-board, I am sure anything worthy 
of support can find it from a larger pool of contributors.

The 'clear and present danger' is loss of momentum. Note the gradual reduction 
in posts here to the d.kernel list, for example.

Fear Fabius, not Scipio.
