Hi Joseph,

The Apple II,II+,IIe do not have a periodic IRQ. The IIc has IRQs

	(snip snip)

decoding was incomplete, and the same RAM location could have multiple

Thanks for that info - very helpful and very much appreciated!!!

Now I just need to know which characters were flashing, but I'm sure I'llfind that info *somewhere* on the net...


Regards,
