The machine seems to be functioning correctly. The strange thing is, I can get the serial card to work booting from an ATDpro floppy and choosing serial. It then communicates with the XP box no problems. That floppy was made on a standard Apple IIe. So the card works in the slot, I just cannot get it into SCC mode by typing:

IN#2

(ctrl-A)

thanks for any help,
