My Pro-380 has built-in color (and graphics). Sound would be possible using the TMS-11 - I have one of those as well... -Steve -----Original Message----- From: owner-hecnet at Update.UU.SE [mailto:owner-hecnet at Update.UU.SE] On Behalf Of Dave McGuire Sent: Friday, May 02, 2014 02:10 To: hecnet at Update.UU.SE Subject: Re: QBUS sound [Was: Re: [HECnet] Parallel computing using DECnet] On 05/02/2014 02:05 AM, Pontus Pihlgren wrote: There are very few PDP-11s that won't kick the living snot out of a Commodore 64, FYI. I've yet to see a PDP-11 with builtin color graphics _and_ sound. 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. 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! -Dave -- Dave McGuire, AK4HZ New Kensington, PA
