I just purchased an Apple /// and noted some interesting differences
between the new Apple /// and one I've had for a while.
Upon turning on the new ///, it displays some garbage, then beeps and
shows "Diagnostic RAM" on the screen, along with a square pattern of
'.'s. Not until I press "Reset", does the comptuer dead the floppy drive
My old Apple /// (which, BTW, I beleive to have some bad RAM) immediately
starts reading the the floppy drive with no "Diagnostic RAM" or need to
hit "Reset".
Also noted:
The new Apple /// has darker keycaps
The older Apple /// has a shielded "Color Video" Port
On the tags on the bottom of the units:
The older has a place to check off either 64k 96k or 128k (128k is
checked)
The new has a place to check off either 128k or 256k (128k is checked)
I understand there was an upgrade to the Apple /// dubbed the "Apple
///+". I was under the impression the '+' was actually written on the
case. Is this the case, or is it possible my newer unit is a ///+? If
its not, what causes the discrepancy in startup procedure? Just minutely
different versions of the Apple ///, or does the older units bad RAM have
something to do with it?
Thanks!

I would guess that the Mac disk controller would be able to read the
later 3.5" Lisa disks. Of course this doesn't help with the 'twiggy' disks.

Right, but in this case it was specified "Lisa II" which means no Twiggies. (Unless there's some _really_ weird modification happening here...)

Aren't there programs that allow PC's to read Apple disks?

Wow! It's amazing how different a CRT looks after three weeks' break.
I don't even feel like sitting at a computer that much anymore.
Sorry to start off again on a bad foot, but does anyone know why a
certain hard drive of mine won't spin up unless whacked firmly
against a table? Is there anything I can do? This is a laptop drive.

I'm looking for some info on old Panasonic plasma displays. For those
of you who have computers that use them for sale, I might be interested
in paying a reasonable price for one just to get a working display so I
can measure the voltages and get all of them working. I have the
controllers for the touchscreen and would especially like to get that
working.
(Forward of message I also sent to Panasonic and ELO:)

Okay -- it's several pages of text and diagrams (screen shots, I think). If I
can scan and OCR it without losing too much, I'll email it. Maybe save as
low-res pics otherwise. Will do that later today...

You sure it's not a working model of a BORG scout ship?
Nobody mentioned *who's* govenrment Harris contracted for!
(Sorry for raising the noise floor, guys. Couldn't resist).

A chap that has gotten some Osborne 1 disks from me has a Lisa II.
Apparently, he has some bootable application software for it, so he is
able to bring it up.
He mentioned that he is looking for a copy of the 'seven disk set' that
was bundled with it. Can anyone help me help him? He is willing to pay
reasonable costs.

I posted a message with exactly that information last night. If you didn't get it, email me, <raoulduke(a)dartmouth.edu> and I will re-send it to you.

I'm in the process on restroing one of these now, so I've had the same
problems.
I think that you can substitute a PB100/140 adapter for the stock MP
adapter and have it work. The MP adapter is 7.5v at 1.5a. I think that the
minimum for startup is north of 2a.
I also just got a replacement CP3045 hard drive, and brand new
batteries. Now I need to bring it up...

I can pull the drive out of the parallel port case and use it with out the
parallel port adaptor as it's IDE. I'd rather figure out how to talk to
it using the parallel port adaptor as it seems to elude everyone.
