I like my IIcx, its a nice OS 6 machine.

Not sure what a dead Mac II is worth on ebay, looks kind of yellowed but intact. I just looked for the PRAMs on ebay but didn't fine the ones with the axial leads (they are usualy there).

If you liked the II then fix it up, I love big box Mac IIs (have a IIfx and a II upgraded to a IIfx).
