I agree with the individual who felt that a price war with APPLE
for something that was exactly the same is probably suicidal, but
what if you approach it from the high end?
Start with:
~1k X ~1k noninterlaced display
68020 with a real MMU
UNIX SYSV Release 2.0
1-4 Mbytes of memory
The applebus interface AND a real network interface:
ETHERNET
Configured as a ethernet'ed diskless node and 1 Mbyte @ $7000
Configured with a 65Mbyte disk @ $10000
Now add a windowing package that pretends to me a MAC and has the
QuickDraw function calls to start with.
What else would someone want? (This is a serious question.)
Of course this presupposes that users like the MAC interface. If they
don't then it is YAWS ( Yet Another Work Station).
I would like some feedback. Either through mail or in the news group.

Sorry. There is software with the ethernet:
1. How do you think we support the diskless node?
2. There is a fully transparent distributed file system which runs
across this ethernet which uses IP as its
network layer, it also does ARP, and it is benchmarked
at 1.5Mbits now, I believe tunable to 2.5Mbits.
3. TCP/IP for those of you into that, though I wouldn't consider
that very high speed if you have been following some
of the benchmark data submitted lately.
(Excelan's 186 board with their rev 3.1 software does
500kbits)
There are a number of people working on tcp/ip for SysV. Excelan has
a Unibus board for the VAX. TWG has some software for the VAX. And
then there is always ATT's which someday may get released.

To clairify my remarks about 4.2BSD; I was only pointing out that the only widely available UNIX-like operating system that supports TCP/IP is 4.2BSD, and that there is no support in System V. As a co-author of a TCP/IP implementation for a Sperry system, I'm painfully aware that TCP/IP and 4.2 are not synonymous. Louis A.

TCP/IP is also available under 4.1BSD, and several sites have implemented it on V6 and V7 systems. Thomas. (breuel@harvard)
