It does? I have an old PS/2 keyboard connected to my P200, and never
noticed anything high-pitched. The space bar is a bit louder then the rest
of the keys, and there's an occasional *sproing* from a stuck spring in a
few of the keys. Other than that, it's a great keyboard. The PC keyboard
is another good one. They both give the sure feel that a letter is going to
come onto the screen (usually), unlike the new membrane (squishy-key)
keyboards that almost have the feel of the Coco 2 keyboard.
The only time that I would think the clicking would give someone a headache
would be if they were locked in a sound-proof round all-white room with no
windows, and dome ceiling, but then again, that's just my opinion.

vacation. And I'm just catching up on the last two weeks.

This means no CHIP-8. :-(

I seem to remember something about the RD series disks (or at least the
RD52 or RD53) installed in a PRO-series machine having the outermost
track *not* track zero...

All the basic stuff sounds fine to me.

I'd like that.
PIO and UART would be extremely useful, probably more so than the
prototyping area -- at least, to me.

That's a good idea.

Yes :-)

Hello, all:
I'd like to start playing with the Motorola Educational Board that I got
a few months back. I downloaded Xinu, a multitasking OS designed for it (and
the dubject of several books). But, I'm having a devil of a time finding
info on the hardware itself.
Amazon has a book on it, but it's out of print. The book is "68000
Microcomputer Experiments: Using the Motorola Educationa Computer Board"
Maybe someone has a pointer to schematics? Anything would be helpful.
Thanks.

What remains is parts 4 through 9.

< < o A protoyping area of .1" spaced plated-through holes, nominally
< < a few inches long by one or two inches wide.
A thought, Since holes cost...
Reduce that to several lines of holes on .1 ctenters with .3 spacing
between lines. That will accept dips in the .3(std parts) and .6
for the wide parts.
