       A couple of months back I scored a rare "QBus Music Board" off eBay.  I don't know a ton about it -- it was made at DEC but was never an official product and I don't know why it was made or for whom.  But it's neat -- it has two AY-3-8912 PSGs to make fun tunes with.  I've never found any documentation or software for it but it wasn't too hard to figure out the registers.  So I did what any of us would do, I wrote a device driver for 2.11BSD (PDP-11) for it, and whipped up a VGM player.  Enjoy!

       Here's a pic of the board itself, it's not altogether that complicated and a buddy of mine has plans to clone it...
