Weren't those chips made by General Instruments?? I've got a handful of brand new "AY-3-1015D" chips, which are either a similar sound chip, or a UART (I can't remember which project these were bought for) and they are labeled with a big "GI" which I assume is General Instruments. They are dated "8319" (May '83??) -Steve -----Original Message----- From: Brian Kraut To: PICLIST@MITVMA.MIT.EDU Date: Wednesday, August 25, 1999 9:37 PM Subject: Re: [OT] AY3-8910 sound chip >Made by Microchip?
