Re: [pups] ACMS (Australian 'puter museum) doomed?

by macbiesz＠optonline.net

Quote from http://www.deadmedia.org/notes/3/034.html: "A copy of his first programme-controlled electro-mechanical digital computer, the Z3, was made in 1960 and put on display at the Deutsches Museum in Munich. A copy of the Z1 was constructed in 1989, and can be found in the Museum for Transport and Technology in Berlin."

I think that the performance would have been approximately that of an 11/40, while the time and effort and parts cost would have been prohibitive for a one-off production. It is barely possible that I have a set of those notes somewhere, although it would take a very lucky random search to find them. carl -- carl lowenstein marine physical lab u.c. san diego clowenst(a)ucsd.edu

[pups] A project--buiilding a device to plug into a PDP-11's bus (or LSI-11)

by Gregg C Levine

Hello from Gregg C Levine I never had the chance to post this here, but one of my reasons for joining our group, was that I was in the process of designing something to plug into a PDP-11's bus, (or an LSI-11). I never accomplished it, because I didn't have the parts here. Nor the computer either to try out my design. I've now discovered that this company, Luke International, http://www.lukechips.com/ which was formed by a group of former AMD engineers, is selling the parts someone would use to clone a PDP-11 processor. And indeed the AM2908 matches those bus specs. I also recall that the processor in question at one point in its lifespan, actually used the AM2901 family of bit-slice processors. The design is still going through the drawing board status, but now that I've found a place that sells those parts means I am much closer. Regarding those systems, if someone in the US, and preferably the NYC area has a PDP-11/53, or an LSI-11, hanging around, please contact me. ------------------- Gregg C Levine hansolofalcon(a)worldnet.att.net ------------------------------------------------------------ "The Force will be with you...Always."

SCO File List - Sort Of

by Rhys Weatherley

Groklaw has one of SCO's legal filings in the SCO/IBM case up that contains a list of files that they claim contain infringing material: http://www.groklaw.net/article.php?story=20031111020447263 It seems to be basically "grep -r (SMP|IBM|NUMA|JFS) /usr/src/linux" with little filtering of the output. The list contains filenames but not the actual line numbers of the supposedly infringing code. So it is pretty useless, but is more of a starting point than we've had to date. I've got dibs on 48 hours in the "how long it takes for the community to find prior public domain sources for all of the above" pool. :-) Cheers, Rhys.

The PDP11/34 saga ... CONTINUED :)

by asbesto

Hi, Do you remember the broken chip on pdp11/34 ? well, i changed the HC74LS175P with an original SN74LS175N. Now i can write and read correct data on memory :))) and the RED LED "PARITY ERR" on the M7891 board turn OFF while pdp11 is running a program. :))) BUT the pdp11 can't boot: the boot loader program stop after few steps. some details will follow in the next days; now i can't make any further test ... -- [asbesto : freaknet medialab : radio#cybernet : GPG key on keyservers] [ MAIL ATTACH, SPAM, HTML, WORD, and msgs larger than 95K > /dev/null ] [http://www.freaknet.org/asbesto IW9HGS http://kyuzz.org/radiocybernet]

solaris source (was Re: Heritage X)

by tuhs＠cuzuco.com

That program was canceled, see http://wwws.sun.com/software/solaris/source/ It was a license, and if you have it, you can not share it with non-licensees. Also it wasn't quite complete. > From: macbiesz(a)optonline.net > A couple years ago, Sun released Solaris 8 source for free. The whole system is full of SVisms, and AFAIK, the source remains free. > > Maciek

You will rue the day you chose them. Don't take my If someone gives me a pointer to the tarballs I'll happily import them into BitKeeper and set up a 32vi.bkbits.net that anyone can use. Unlike sourceforge, we're about quality, not quantity, but even so, we have 1/3 as many files under revision control and no performance problems. It's not really sourceforge's fault, they choose CVS and CVS sucks. As Ted T'so said recently "CVS is not the answer, CVS is the question. No is the answer." :) -- --- Larry McVoy lm at bitmover.com http://www.bitmover.com/lm
