My (incorrect) implication was that FORTRAN was the only language with which one could use overlays. Overlays are implemented by the linker.

Well, overlays do not depend on FORTRAN, you can use that no matter what language you choose. Yes, of course. I don't know what I was thinking. Thank you for the correction. I myself have only actually used overlays with FORTRAN; that was probably the source of my error. -Dave -- Dave McGuire, AK4HZ New Kensington, PA

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

On 05/02/2014 03:28 AM, Pontus Pihlgren wrote: 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) I don't know who made it; I will check. It's an amazingly simple board. The TMS9918 is very easy to use to begin with...All this board appears to be is the standard TMS9918 app note circuit with some glue logic to connect it to Qbus. It should be trivial to bring up and get graphics out of if I can find out where its CSR sits. -Dave -- Dave McGuire, AK4HZ New Kensington, PA
