ADM-3A lower case

I' ve been intermittently looking (for many years) for a lowercase 2513 for my ADM-3A. I was really happy to see your post and find that others are interested in restoring this '70's nostalgia piece! I remember in 1977 how impressed I was with the blazing 1200 baud modem speeds, since the hardcopy Decwriters at the Univ. of Maryland were 300 baud. (Also I have a working rackmount PDP-8/I, with a "University Computing Company" front panel). I wore out my keyboard this weekend searching online for a 2513. Pure unobtanium. GI made them (I believe the p/n was 2513CGR-002 for the lowercase? -001 is in the socket so obviously the uppercase). Just as well I didn't find one, I never knew the address lines were flipped.... or am I misunderstanding and it is the direct plugin? thanks Charles
