Yes, it is quite possible, but I am only familiar with the Bridgeboard itself. Background: On the Bridgeboard, there is really one chip GENERATING scancodes, and another chip decoding them. All you need to do is put a keyboard BETWEEN these two chips, and sever the connection between them. What I did was this. There is a connection between U40(pin 62) and the Test Connector (j7 Pin 3). Cut this line closest to U40. This is the KeyBoard DATA lines. Now, Hook your Keyboard up to pin 3(KBData), pin 4(KBCLOCK),pin 5(Reset/PwrGood), and of course Pin 7(+5V) and pin 8 (Ground). I had been running with a keyboard, and a Mono monitor on my Bridgeboard for some time. I have now upgraded to an A3000, and do not want to embarass it by installing a Bridgecard. :Later -- Opinions expressed in this message are my Own.
