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.

Also, to run the nifty MacSoftware which will eventually become available, you're gonna need a 3.5" drive (somewhere on the network). You'd also need to kluge in support for the rest of the OS somehow. Personally, I think Macs make sense as super-intelligent terminals; you do need a UNIX box to handle FP, databases, and communications, but is it really sensible to have it handling graphics also? True, Mac screens are kinda dinky. . . . Sinc, Kevin Eric Saunders kevin.lasspvax@cornell.arpa

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. marty {wivax,seismo,bbncca}!cadmus!schoff schoff@cadmusv.ARPA

Contrary to popular misconception, "4.2BSD" and "TCP/IP" are not synonymous. It is quite possible to have the latter without the former. -- Henry Spencer @ U of Toronto Zoology {allegra,ihnp4,linus,decvax}!utzoo!henry

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)

TCP/IP for the Mac is in the works. You will still have to acquire some form of AppleBus router to use it, though. Please do not ask me for any pre-release copies of the Mac Internet package. -=- Tim Maroney, Carnegie-Mellon University Computation Center ARPA: Tim.Maroney@CMU-CS-K uucp: seismo!cmu-cs-k!tim CompuServe: 74176,1360 audio: shout "Hey, Tim!"
