Having listened to the dismal sound of my XT for some time now, I want to interface an AY-3-8910A Programmable Sound Generator to it and write an appropriate device driver. The preferred interface method would be via the serial connector as I want it to be easily attachable to any XT/AT I happen to be using. Has anyone (done)/(heard of) a project similiar to this one? -- Shawn Instenes UUCP:...!tektronix!reed!percival!shawni "Part-time Temporary Data Entry Clerk", Evaluation, Portland Public Schools

Instead of using the serial ports, wn hy not use the printer ports? A lot of systems today have extra printer ports, which are parallel out ports. The design would need some extra lines, tho - you would need to select which registers you need. The extra lines coulb d be faked by s a simple addition of a latch and some logic - say, bit 7 high would be the latch/data e select lines.
