CA9277B Advanced Super I/O Controller ISA für 4-Floppy Laufwerke

fritzeflink · 1. September 2020

Auf meiner Slotcpu Kiste habe ich heute den Kontroller mal getestet.

CA9277B Advanced Super I/O Controller

Hardware SlotCPU AMD386-33 (ohne Schnittstellen) , Matrox VGA, 3C509 NIC und ogen genannten Multikontroller mit DOM als IDE. Floppydrives 360, 1.200 und 1.400Kb

Die Installation war problemlos nachdem mir eingefallen ist, das ich doch besser die "Z" Taste für Y(ES) nehmen sollte.

Falls ich mich nicht irre:

Für SD werde ich doch den AHA1522A nehmen, aber mit 4 Laufwerken hat es schon was.
