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.

QBUS sound [Was: Re: [HECnet] Parallel computing using DECnet]

Fair enough :-) 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! Which one is that? I have a Matrox card and one of the VSV cards (can't remember which one) /P

Me neither. The 64 probably outsold all models of 11 taken together. That's certainly possible, but one cannot argue that their target markets were even remotely related. Or even aware of each other's existence, for tha tmatter. so it depends on your application and measurement I suppose. We were talking about distributed math apps.

Parallel computing using DECnet

Oh man so we are going to do amazing things with 64 KB nodes ha ha. I like fractals sounds like a good application for what we have. ...we do have 64KB available right? :) Sent from my iPhone On May 1, 2014, at 5:58 PM, Cory Smelosky <b4 at gewt.net> wrote: On Thu, 1 May 2014, Jovan Trujillo wrote: Alrighty so no dynamic memory management.
