Mouse:
I have a Logitech Mouseman Pro serial/PS2 that I have literally used as my primary mouse since 1996-1997... the ONLY mouse that I've ever used since I first bought it back then.
That mouse has the BEST "feel" to it and the most sensitive and easy to push buttons of ANY mouse that I've ever used before. It ALSO is the absolute BEST tracking ball mouse KNOWN TO MAN!
I would kill for an optical serial/PS2 version of that mouse, as none of the new-fangled mice (including the high-end "gaming" mice) "feels" as nice and comfortable to me. Plus, I DETEST mouse wheels, simply prefering a regular 3-button mouse.
Keyboard:
Not necessarily "old school", but the best damned US$10 dollar keyboard that money can buy (that is... *IF* you can still ACTUALLY FIND them!), a BenQ model 6511-M 😀
Mouse Pad:
The best US$4 dollar mouse pad that you buy, an OfficeMax budget mouse pad http://www.reliable.com/catalog/sku.jsp?productId=ARS22003 . Full sized, and the older styled fabric surface (which is smooth as silk)... PERFECT tracking for your old Logitech Mouseman Pro ball mouse 😀
