RE: Re: Kieran's comments was Last Night in London?

["Mick Furlong" <dorsai@xxxxxxx>]

Yup I thought it would be java nice and portable ;)

well my favourite heinlen book is Time Enough for Love but I like a lot of
his stuff.

hmmmm interesting do you know if any of the sparc boards are PC
compatible(PCI)? reason is I have a couple of 9gb sun fibre channel discs
and I would love to run them off my PC they should scream;)problem is I
cant
find a damn fibrechannel PCI card. Might just flog the things.
