As others have said, it's a 18011, and you are looking at the serial
number.

IIRC, It was made in late 1995 (1960+35). The 05 is the 5th week of HP's
Fiscal year that begins Nov 1 (still today), which I think puts the
date of manufacture between Nov 29th and Dec 6th 1995.

It's also a darned fine bit of kit :)

(Sorry, I know I'm sad and bad, I just couldn't resist :)]

at HP!)
