[MRCA] Early Integrated Circuts

[Ray Fantini]

In the ongoing journey of moving forward into the past I have now decided that my life won't be complete until I obtain some series 51 RCTL integrated circuts. My limited understanding is that they were simple gates designed for missile and space applications in the early sixties and have package numbers like SN51A, SN512, SN516 all the way up to SN5191 So if anyone has any they would like to sell or trade or any of the information regarding that family of devices please contact me directly. I may have a SN516 arriving soon and although I know it's a dual 2 input NAND/NOR gate would be good to have a pin out for that device.
The goal is to build up a little demo board with some buttons and leds where you can see the gate at work. Won't be fun like gaming or being on the internet or something like that but it's what I am aiming at.
