Dave -
Your timing is good for asking about a ProcTech tape archive. I've been
working with another Sol owner and will soon have a CUTS programs CD-ROM
(just use a portable CD-ROM player in place of the cassette player) with as
much of the original software as it's been possible to find (TARG, BASIC5,
TREK80, FOCAL, PILOT, etc.). I also have a tape from Proteus, the ProcTech
users group, which I can send you immediately. Email me you address and
I'll pop it in the mail.

David,
You are about to discover how temperamental the Rocket really can
be...
I dare say you know that Radius still have the latest
RocketWare software and a brief FAQ available on their ftp site.
There's another utility there called "lift-off" that checks the
configuration of the host Mac for timing senstitive cards that may
conflict with the Rocket.
Have you tried knocking up a minimal system floppy (eg disk tools for
System 7.0 with the RocketWare extension added) and thried booting

Yes it is. So it sounds like it's original.
There were 2 motherboards, a 16-64k and a 64-256k. The former was the
original one. The latter has a B in a circle stamped on the back plate.

ISTR that Apple were looking at a diskless Mac project -- the sort
of thing that would interest education. The Classic was available as
a hard diskless model according to the manual but I've never seen
one. Of course the diskless idea would never have worked very well
as there was nowhere to install extensions/INITs and the diskless
Classic was stuck on System 6.0.x and there was no ethernet
capability.
(An aside: Sonic Systems later developed The Diskless Mac (TDM) which
used a boot PROM on an ethernet card to attach to an AppleShare
server where a System image was stored. This worked with System 7 but
the hardware range was limited.)

I have made contact with an individual who has
what he describes as an Altair 8800 which is
in an "Attache" case made by Icom in 1976. Would
appreciate any information about this "Attache".
Is it a very desirable thing. Were very many produced, etc?
It has MITS
boards (CPU, IO, disk controller) and power suppy.
He wants to trade it to me for an Imsai 8800.
Would that be a good trade on my part?
Thanks,
Bob

A side note: I've got VHS tapes that are 10-12 years old and still look the
same when played. I find that most tapes fail with heavy use, not age
deterioration.

The Mac Classic contains a complete System 6 installation in ROM that
you can boot from. Sorry but I don't have the docs handy, but I think
if you press Command-Option-Shift-X on startup, it'll boot from the
ROM. Another way that should work is Command-Option-Shift-Backspace --
this key combination should work on any SCSI capable Mac to supress
booting from the default SCSI boot device.
Once you've booted, you'll need to scrounge a copy of Disk First Aid
or a third party utility to check the hard disk. Do you have system
install disks etc for the machine?

Hmm. The Deutsches Museum is a 'hands-on'/'interactive') museum
since the first years, and the combination of historic displays
and learning works fine - at least for me.

Exactly my idea of a display ...

Aha, y'all thought I was being cute with the subject... 8^)
I re-watched BttF II the other night, and noticed that in the window of the
shop where Marty buys the sports almanac was an interesting item, an
"antique computer". (A mac Plus-ish machine.) I'm not sure exactly what
year II came out (about '87-88?) but that was pretty insightful, I think.
('Course, they were pretty cool movies anyway.)
