Well current state of the art in the pc world is a 486/66 (32.4 specint 16.1 fp)
In six months the 66 Mhz pentium will be state of the art (64.5 specint 56.9 fp)
and a good motherboard like micronices VESA is over $1000 with a 486 66 in it.
Last year a 486/50 ISA was over $1000. Don't forget that the 486 motherboard
doesn't have video, ethernet or scsi.
So if we can get the 4200 (55int/30 fp) 4000 (62int/63fp) going it seems
that even in 6 months we would be competitive if it's under $1000.
If we use the arc 100 chipset we have nothing to design, all we
have to do is order the parts, and contract out the design of the motherboards.
Oh yeah and port linux ;-)

Well I don't expect anyone to sell 486 motherboard ugprade over the next
6 months because of problems with software/integrations/hardware compatibility.
Complete systems will compete with complete pentium/486 systems, but I don't
expect any direct competition with 486 motherboards.

ACER isn't selling mothebroards, and ACER needs to make a profit, and
ACER's machine won't run linux.

Well hopefully everyone will agree the arc 100 design is better and we
will have to do NO design, just use the NEC design.

Well the arc 100/150 look even better. (MCT-ADR MCT-DP)

Well I personally prefer the powerpc. It run's gcc, gets more done per Mhz,
very elegant, reasonably priced, and has the largest onchip cache. But the
simple fact that there exists a mips 4000 board design outweighs any
advantages the powerpc has over the mips 4000 series. Unless we find
a ready to use powerpc motherboard design of course.
I'd really doubt the mips chips will have any problems, they are faster
then the pentium, run windows nt, and have SGI/MIPS and various pc companies

Well the 486 is an ugly architecture, and is slow especially in fp. (not
to mention I'd bet that the 486 specmarks are more optimized then anyone elses.)
If I can get better price/performance on a riscy motherboard with everything
on board, then I can get with a 486 motherboard+video+scsi I'll buy it.
[ deleted long speculation on the number of free unix users and extrapolating
market for the riscy board]
There are no doubt that there are MANY free unix users, but MANY of those
are running with <= 4 MB ram, <= 386-33, IDE disks, tident or tseng video
Most free unix users are college age or so, and don't have the better part
of $1000 to upgrade there system that doesn't run winNT or dos software.
But I hate the 486/586 design, and microsoft software, and hope to
get a riscy motherboard to run linux. So I can have a workstation at home.
