I have been looking into this also. Here is a good link on AT Keyboards http://www.beyondlogic.org/keyboard/keybrd.htm Michael Holley www.swtpc.com/mholley ----- Original Message ----- Date: Wed, 28 Aug 2002 10:34:46 -0700 (PDT) From: Ethan Dicks <erd_6502(a)yahoo.com> Subject: Need PC-AT "keyboard BIOS" docs To: cctalk(a)classiccmp.org Reply-To: cctalk(a)classiccmp.org I had this idea for a keyboard adapter for classic machines, but I don't understand the 40-pin "keyboard BIOS" microcontroller well enough to know if it's possible... So... is there a good place (on the web) to learn about the "keyboard BIOS" chip? Alternatively, is there already a project like this that I can clone? If anyone has any examples of how to attach a PeeCee keyboard to a 68000 or 6502 directly, without going through a UART, I guess I'd be interested in that, too; but since I was already planning on sticking a Z8530 or 6551 or 16550 chip on the OMNIBUS board anyway, I might as well use the same serial port for all embedded console I/O. Thanks for any pointers, -ethan __________________________________________________ Do You Yahoo!? Yahoo! Finance - Get real-time stock quotes http://finance.yahoo.com
