Indeed, the 82C42 is a keyboard controller. The original 8042 was a microcontroller that had the keyboard controller code burned into the onboard ROM. I am using an 8242 variant right now from VT for a multi-cpu 68k project. There are a few different variants, but the most common one has the standard PS2 keyboard+mouse support. http://www.bitsavers.org/components/viaTechnologies/VT82C42_Keyboard_Controller_199511.pdf http://www.bitsavers.org/components/viaTechnologies/VT82C42_...
