Hi, does any one of you have a good reference on keyboard controller?

Description of meaning / all bits of all kbd registers, some theory on how to use them, etc. Something more than just "working example"

thanks.

Back on topic... anyone knows what does the "lock bit" of "keyboard controller status" (read from port 64) means?

I thought it is some long-term disabling of keyboard, but apparently not.

hehe, I still have a Cx586 on a case with that Razz (I have that case since my first PC, a 286, then a 486SX inherited the case which in turn was inherited by the Cx586).
