Lines: 14 From: conde.osbuno...@Xerox.ARPA Does anyone have info or pointers to articles on the CMU 3M Machine? It's been publicized after Steve Jobs quit Apple for build a workstation with the 3 M's: 1M x 1M bitmap, 1 MIPs, and 1 Meg RAM, running UNIX, and is supposed to be built in coopereration with IBM, HP, SUN, ATT, DEC and Apple. It's also supposed to be dirt cheap. I know about the plan to wire CMU up, some info on the SPICE machines, but the name 3M is new to me... Dan Conde conde.pa@Xerox

(Any ideas on whether Jobs will build his 'Next' machines with an open bus architecture?) Right now the ITC is using Suns and MicroVaxes, and we're all waiting to find out whether IBM will require everybody on campus to sign non-disclosure agreements in order to be allowed to use their advanced workstation. MIT's project Athena is using mostly DEC hardware, (MicroVaxes, 750's with VS-1000 graphics terminals). They're supporting the CMU window manager calls as well as their own. (This will be a big win, especially if the compatibility is extended to other components of the systems. Unfortunately MIT's idea is to provide remote services through a remote procedure call (rpc) interface, while CMU is using sockets. Both systems use Berkeley 4.2 Unix.) I hope the '3M' idea isn't viewed as the ultimate solution, since everyone know that an open architecture is a requirement to keep up with the state of the art. -- - Ralph Internet: ral...@c.cs.cmu.edu (cmu-cs-c.arpa) Usenet: ral...@mit-eddie.uucp Fidonet: Ralph Hyre at Fido#385 (Pitt-Bull) -- - Ralph Internet: ral...@c.cs.cmu.edu (cmu-cs-c.arpa) Usenet: ral...@mit-eddie.uucp Fidonet: Ralph Hyre at Fido#385 (Pitt-Bull)

Both systems use Berkeley 4.2 Unix.) > To correct some missimpressions left by Ralph's Article: 1) Our window system (X) uses a protocol ON TOP of a stream, similar in principle to Andrew, the ITC CMU window system. It currently runs over TCP, though we ran it over a DECNET stream one day for interest's sake. We support a fully heirarchical (sub)window system, and allow overlapping windows. X is considerably more powerful than Andrew, but we have not the applications code that Andrew does. 2) X currently runs on VS100 displays, the VS 2 (uVaxII with QVSS) workstation and a color display. Other ports are in progress. The client programs (since X is a formal network server) have been ported to a Sun and will talk to a Vax display, but the X server has not been ported to the Sun (where most of the work lies; we do not have the manpower to put into it here). (Any suckers, ah, I meant volunteers out there?) 3) The Andrew emulation package is not finished, and I for one will not count my emulators before programs run under them. No promises as to if/when it will be done. We hope "soon".... 4) the Vs100 implementation of X is available from MIT at nominal ($100) charge, no license (additional to a Berkeley licence) is required, and X will be on the 4.3 tape. An incomplete VS2 implementation is also on the MIT distribution (soon to be finished as soon as the "last bug" is found).
