Purchase from guy in Elizabeth neighborhood in Charlotte.
Wasn't sure if it was a 512k upgrade or 128, but the Serial Number showed it as a 128k, so I was hoping it was. The logic board is indeed a 128k, but it has some mods done (all memory chips have been socketed and a new socket and chip was piggybacked onto another with some resistors. Basically making it a 128k with 512k memory (aka FatMac).
Analog board was having issues, so I took it from my Mac Plus that was an upgraded 512k.
Floppy drive works.
