I can understand why the Apple ][ has a
significant following - it was a
machine that was 'open', that hackers could get inside, etc. But I also
know that it's not a good piece of hardware design, and thus don't put it
high up my list of interesting machines.
Perhaps I am merely biased from growing up with the Apple ][ at school
and, later, at home, but I would say that some of the design is
ingenious. I do know that many a programmer has complained about the
Some of the Apple ][ design is ingenious - I'll agree to that. But, IMHO,
there are plenty of other 'ingenious' machines where the aim was not to
save a 10 cent chip, and thus the resulting hardware is a lot more stable.
I'll admit now to having come to the Apple after a number of other micros.
My Apple ]['s have _always_ been a lot less 'stable' than my much-hacked
TRS-80 model 1, my Pets, my S100 systems, etc. It may be that I didn't
spend enough time learning about the Apple so I didn't work out 'fixes'
(as I said, my model 1 was modified...).
The Apple ][ TechRef (and many other Apple ][ manuals of that time) are
_excellent_, BTW. I learnt a lot from reading them. But I'd never use some
of the tricks that were pulled there in my own designs.
arrangement of the high-resolution screen in memory
(which was
arranged the way it is to save components). But, I find the economy of
this feature fascinating.
I find it a kludge. We're both entitled to our views, and I have no desire
to start a flame war over it. Please note that I can find kludges in just
about any machine you care to name.
The Apple ][ and its successors had great capabilities for expansion
(with the possible exception of the IIc and IIc+). A IIe has the
capability of using a hand-held scanner, for instance, with the right
slot card and the right software. I'm sure the IIe wasn't designed
originally for that task. There are numerous other examples as well.
Well, I doubt that my 1972 PDP11/45 was designed to use SCSI disks, but it
does now. I doubt my PERQ was designed to use 9-track magtape, but thanks
to a Dylon tape interface it does now. And I certainly doubt that my Tandy
CoCo was designed to have 3 extra serial ports and an _Apple_ digitising
tablet, but a couple of homebrew boards have allowed it to.
Just about _any_ 2 computer devices can be linked given enough time. It's
not always worth the effort, but it's often fun...
