It was the Fantastic 4. I was thinking about something else and got the
thought mixed up with what I was writing...

This is where we need to go. I really what to know how people defined their
Apple experience(s). Since I cannot see the world as they do, I need to hear
what made Apple 2 so special for them. I've already designed in what made it
special for me.

I heard you quite clearly. You would like to take advantage of the large
supply of existing PCI cards. The core of the problem is that I don't know
any hobbyist with the skill set required to design and build their own,
custom PCI card. For me, that was a big part of the warm-fuzzy... Given that
PCI has gone through several revisions, even some commercial cards on the
market will not successfully run correctly in all PCI systems. Compound this
with the fact that since a) all PCI cards will need a new ROM for the new
65832 based machine, and b) somce manufacturers will not release the info on
how their cards work so we can build customization kits, the vast majority
of the PCI card market suddenly becomes inert. That is the second reason why
I won't use PCI. I've already explained the first...

Under those conditions, then I have to agree...

I already knew that. Unlike the Apple ///, which was Apple's 1st attempt at
ridding themselves of the Apple II line, the Apple IIe was built from the
beginning to be an "Enhanced Apple II". That they borrowed technology from
the /// was a good thing, but that they made A2 compatible without
restrictions was an even better thing.

The lack of upgrade slots was the first sign that it was no longer an A2.
The 10"(?) B&W monitor was the second sign. The lack of A2 compatibiliy only
verified the suspicions even more. As of the Macintosh, the entire A2
library was defunct. It would've been different if the Mac would have been
designed with the ability to run the wealth of legacy software that existed,
but that's water under the bridge now.

Not really, but if you've read this far, then you already understand why PCI
wouldn't suit. The II bus does have it's limitations, but the extension I
will make will overcome all of them. Each slot will also have a buffered
latch on it so that it can still support the older 1Mhz cards. That means
that it'll support the old Apple card base, a new card base, and the ability
for the average Apple techie to design custom cards. This is the effect i
want.

The only way I can think of to make that work would be to use a token-ring
style setup so that each processor is accessed in turn. The processor
controller would have to be able to buffer as many data fragments and
request fragments as there are processors. That get's tricky really quick.
It shouldn't be too hard, but a PGA is a better idea, IMHO.

You can always use a SCSI card...

Do you see the difference between this and the past few posts? In this one
you told me what you'd like to see. That I can handle. In the others, you
told me that my idea was non-viable for whatever reason. That I can't
handle. It would be different if the idea were ready to go to the prototype
stage, but right now it's just an idea for which viability is not a concern.
