Certainly seems nicer than when I last did anything with NetBSD (about 2 yrs 
back, so that's about 1.2-1.3)

if you type reboot, it doesn't trash your cmos settings (that's basically it, 
RO4 actually checks the checksum on a reboot, one thought I've just had is 
how safe it is with the clock, (the clock updates the time in the cmos at 
some point)  Anyway this is a contact risc-os ltd I think (didn't have time 
at the show to quiz them.)

Yep, mozilla didn't compile for me either.

It crossed my mind that we should increase the number of modes available at 
boot time.

Great :)

There are some interesting machines that seem to be popping up, companies 
approached:
Riscstation: Willing to lend a riscstation to a developer to get it working 
(I believe it's very much like A7000 series hardware (but has fp on board:)
Castle: Willing to give info out on cards (including kinetic).  however 
they've requested that any really interesting parts are kept obscure in the 
code.
Cumana:  Said they've given tech docs on scsi card to scott stevens about 3 
yrs ago, but willing to do so again.

One company I didn't get time to speak to was millepede (or is it 
microdigital)  anyway they're the ones doing the omega, but they also mention 
a dual processor (including xscale chip) pci based system.  Could be worth 
approaching them via email.  Anyway I've a bunch of email addrs to mail and 
talk to people.
