The general format is <partnumber> <description> <date> <partnumber> falls off if there isn't one. I started using this a few years into the project, so the early stuff isn't this way. The <description> has been getting longer since I moved to a server that supports long filenames. And, to answer your earlier question, I don't think I saved any AED terminals. I do have the schematics, users manual, and rom source. The AED 512->1024 are a single large PCB. The 1280 was a total redesign, replacing the 6502 with a 65816, and a 12 bit 2901 for line drawing.
