content: Interesting how this version has a ROM emulator instead of the usual hard wired ROM.Rather useful for a public display of how the computer works, as can change the software at will.

content: As someone who, as a child, witnessed the moon landings, I am simply very glad that there are people recognizing the historical value of these masterpieces, and attempting to document and recreate it before the details vanish.Although not as famous, the Apollo Saturn V Launch Vehicle Digital Computer (LVDC), is also part of this history. Fran Blanche has an excellent video on this computer:

"Apollo AGCDestruction" --> YES!

content: The wiring in the modules was originally welded but this was beyond the capability of the restore team so they used solder.

content: Quote from: German_EE on June 11, 2019, 05:54:18 pmYes, but the posts above was about the pins of the modules, not internal in the modules. I would think that if the put solder on the pins/connectors they would have a hard time inserting them in the backplane again....
