Hear, Hear! Not to be a wet blanket, but it might also be enlightening
to try to predict what the cost of competitive products will be at that
time. I understand that DEC Alphas are already available for ~US$5K,
at least to selected WindowsNT developers. And that's complete, with
memory, tube, keyboard, mouse, disk, and CD-ROM drive.

How much do you think this Taiwanese machine will be selling for by
the time our board is able to boot Linux? Particularly when the
prediction of that time has to be adjusted for time spent bickering
about fundamental design decisions, like 'dumb frame buffer vs. VESA
local bus connector' and 'IDT R3051 vs. IDT R3081 vs. NEC VR4000PC
vs. NEC VR4200' and 'complete complement of I/O on board vs. ISA
I was really disappointed when the IDT 3730 didn't materialize. I
think that probably set the timetable back _several_ months. And it
looks to me like we're even more caught up in pursuing Vaporware (tm)
chips now, rather than accepting the lesson of the 3730 and
designing with parts that are available (in small quantities) now.
What I mean about quantities is that we could probably have the 3730
in three months if we could convince IDT that we'll be buying 50K
per month in 1994 and 1995. On the other hand, it's entirely
possible that the PowerPC will really take off and the VR4200, even
the whole MIPS 4000 line, will be abandoned because there's no
At the risk of repeating myself, let me say again that I don't think
that this project will lead to a state-of-the-art workstation at a
bargain price. We just can't compete with the large-volume
manufacturers. But I still think it's worth doing, and I still
think there's a (small) chance there could eventually be many
thousands, even tens of thousands of the things built over the next
Does anyone have any usable estimates of how many
Linux/386BSD/NetBSD machines there are? A month or so ago Bill
Jollitz was throwing around the number 'a million' for 386BSD alone
(but of course I take that with a grain of salt). But say there's
something on the order of a million of Linux & 386BSD & NetBSD
combined, worldwide. Obviously, all of these people are adventurous
tinkers, or they would stick with 'supported' software. Do you
think that 1% of those people might buy our board, if they could get
system software that boots up and basically runs, and if they knew
they could get compatible motherboards from at least two or three
manufacturers around the world, and all their other hardware needs
from their local discount computer retailer, and all the 'support'
they could possibly want from net news and mailing lists?
One percent of a million is ten thousand. Even if I'm off by an
order of magnitude it's still one thousand to one hundred thousand.
Enough to support a pretty active news group. And if every one of
them has the 'sources' of the hardware design, enough to deal
compatibly with obsolete components for a long, long time.
