"Our physics lab was just given a Commodore 64! We can have one user at a time and we have no computing power." "The art department has just received a PDP-11/70!" </badjoke> so it depends on your application and measurement I suppose. We were talking about distributed math apps. Distributed math apps that should GIVE AUDIBLE OUTPUT. I'm told there were, probably third party, sound cards for qbus. Has anyone of you seen one or know more? I haven't. I have a really neat Qbus card with a TMS9918 sprite-based video chip on it, though! That's interesting! -Dave -- Cory Smelosky http://gewt.net Personal stuff http://gimme-sympathy.org Projects

Parallel computing using DECnet

by mark＠wickensonline.co.uk

Might be a long shot but is it worth trying to track down the original author of the article and see if they've got any code lying around? My Unix account has moved with me since 1994-ish so it could be a possibility they have code available. Mind, I'm probably not alone in this amongst you rabble ;) Mark.

However, for many machines, that needs to hold both code and data... (For some, you can have 64K code and 64K data.) There are very few PDP-11s that won't kick the living snot out of a Commodore 64, FYI. :-) But using FORTRAN, we could potentially use overlays and such. Well, overlays do not depend on FORTRAN, you can use that no matter what language you choose.

Well, graphics cards do exists, so that is obviously not a problem. :-) As for sound, it is just an analog signal anyway, and there are plenty of D/A cards around. ;-) Johnny -- Johnny Billquist || "I'm on a bus || on a psychedelic trip email: bqt at softjar.se || Reading murder books pdp is alive! || tryin' to stay hip" - B.
