My brother picked up an Apple IIgs for me from the thrift store yesterday. I am getting an error: system bad: 02010400 when I run the self test by holding command+option during boot.
From what I can determine, this is a ram error. I removed the add-in ram card for now and re-ran the test with the same result. Does this error show ram chip bank 01 is bad?
If so, would this be the chip "UM1" on the mainboard? And last, are these the correct replacement chips: http://www.jameco.co...DRAM_41574.html
