Hi!
So, i managed to get my hands on a LTN-51 CDU (PT NO 663550-04-01) and I noticed it on one of your photos and im trying to power on mine, do you have by any chance the pinout for it? At the time i have only figured out that pins b and a (E and D on the J2 connector) are used to turn on the lights for the numbers, DIM and WPT.
I was also wondering if anyone had any idea on where did this bad boy flew. Its serial number is 0983 and its manufacturing date is 9-20-74.
Any info helps at this point, so thanks in advance
BTW: Awesome job with the FIN-RPMD!!
