The Story
Mac 128k FatMac upgrade
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.
