New finds - swap & question

Hi all, Yesterday I found some new nice things, 5 Digital handbooks. One of them is the 'Small Computer Handbook' from 1967 and describes the PDP-8, 8/S, LINC-8 and a product catalog. There are also some pictures of the assembly line. The product catalog shows pictures of the PDP-8, the PDP-8/s, the LINC-8, the DISPLAY-8, the PDP-9, the PDP-10 and a test system Dec used to test their Flip-Chips. Since I have restricted myself to PDP-11's only, and I need 2 little boards, I'm offering this book for swap for two W970 cards (or 2 W957 cards). These cards are standard single width cards to attach a flat cable with it. Has anybody heard of a 'QBus music card'? This is a dual width card with 2 AY-3-8912 IC's and an audio out plug mounted on the card. Where was it used for and which application can control it?
