Yes, please do. :-)

OK, I wrote this assuming it would be the only source of IRQ, but the check
is easy to add.

I too want to expand this buffer size, but I'm not sure if it's necessary to
expand it for incoming characters from interrupts. It don't think it would
help too much with the IIe firmware 80-column scrolling that will lock out
interrupts.

Now if you're talking about making a big buffer simply to capture everything
that's been sent in to the SSC, then yes I would agree that would be a good
idea, but not in the IRQ routine as I currently have it designed.

I was thinking about adding a Control-P command to route input to a printer.
Then there could be a Control-D to save to disk.

Yes, because I want to add slot independence, and I think some more of these
other suggestions too.
