Macintosh IIsi: Math Co-Processor Not On Logic Board


Are the math co-processors on the Macintosh IIsi adapter boards socketed
(and removable) or are they hard-wired?

The co-processors are soldered onto the Macintosh IIsi adapter boards
(this is true of both the Macintosh IIsi 030 Direct Slot Adapter Card and
the Macintosh IIsi NuBus Adapter Card).

The co-processors are not soldered onto the IIsi logic board itself.
