Is it possible to see what year the keyboard is? I'm looking for keyboards prior to 1992 when IBM still made the keyboards instead of Lexmark.

Yes it is possible. These are IBM original keyboards. As old as 1987 - 1992 give us a call if you'd like. 516-693-1530

Does the keyboard come with the USB adapter?

I did not expect a USB and the keyboard did not come with one. I was very pleased with the keyboard. GD.

Is there a specific, recommended PS/2 Connector that will work with a Haswell, rMBP?

a ps/2 (female) to usb (male) connector is what I used and it works fine on my older pc, (core 2 duo) (windows 7) which has both USB and USB 2 interfacesI don't know about USB 3 slots, but your computer probably has a combination of them, so it should work. I can't vouch for windows 8, if that's what you are running, since I haven't tried the keyboard on a windows 8 machine. It's a killer keyboard.

What is the difference between an IBM PS/2 Model M and a Lexmark PS/2 Model M Keyboard?

The IBM keyboard that I have with a 1990 date has removable key caps (nice for cleaning or if you want to use a non-standard layout like Dvorak). My Lexmark keyboard from 1993 does not have the removable key caps. Also the IBM coiled keyboard cable has a round cross section and is removable. The Lexmark coiled keyboard cable is not removable and has a flat cross section. My IBM keyboard has a gray 'IBM' logo. My Lexmark keyboard has a blue 'IBM' logo. The typing action of both keyboards seems very similar.
