:-) perhaps we are talking past one another here, but I suspect that you
haven't gotten my point.

But that *isn't* the Apple II bus. Woz's bus is a 1 mhz 8 bit bus. That's the
bottleneck. Even on the IIGS, the slots are still 8 bit 1 mhz slots. I'd be
surprised if you could push it much past 8 mhz. Pleasantly surprised, but
surprised none the less.

I care. Why would you create a slot that will never be filled?

:-) but the //e didn't die until 16 years later - what kept it alive wasn't
speed, but software. Over 20,000 titles. Still, you do have a point here.

Then you don't need extended slots - or all 7 of the II slots.

Actually, I use various machines, depending on what I'm doing. But I thought
you said in the post above that you would put SCSI on the motherboard, which is
why I wrote "ditto." Perhaps I was wrong, if so ya got me. :-)

Well you see, that's my point. There are so very few hardware projects around
because there are so few people to sell them to. Like with modems, an existing
bus (ISA/Microchannel/PCI/Nubus) that has cards I can already buy and use (I
guess that rules out Microchannel and EISA) would make more sense than an
extension to a 23 year old bus. Of course, if you were going to do this just
for your own pleasure have fun, and I'd love to see it run sometime. But I
wouldn't buy such a motherboard, because I sincerely doubt that there would
ever be cards available to put in the slots. I'd love to be proven wrong
though!
