Is it just me, or are others on the list not pleased about what seems to
be a sudden influx of raw HTML code posted here?
Sorry to be such a snit about this, but wading through that crap is making
it a lot harder to read the articles. The Web is not the Internet, and the
Internet is not the web. Last time I checked, CLASSICCMP was a TEXT-BASED
mailing list.
Rant mode off. We now return to our regularly scheduled posts. ;-) BTW, I
would ask those who are posting raw HTML code to please stop!

"Our science can only describe an object, event, or living thing in our own

Hi!
I had some luck today, and picked up and Amstrad CPC464, two IBM JX's,
and an Altos 486. No idea what I'll do with the spare JX - but they are
neat. Did it take JR cartridges, or ones of it's own? And does anyone
know whether they had to have their own system disks, or could they boot
off standard DOS? Currently I'm stuck with the default BASIC.
The Altos is something new for me - it appears to be from 1984, and has a
number of ports for terminals on the back. It says that it is running a
4186 as the cpu, but I don't know that one and the cpu is covered by the
power supply. Was this actually the 80186, or something else? And does
anyone know anything about Altos and the Altos 486?
Thanks heaps,
Adam.

that's the one. alan turing defined these machines as part of his
contribution to the proof that mathematics has some unprovables.
anything that can be proved, period, can be proved by a turing machine;
anything that a turing machine can't prove is unprovable. kurt godel
(most famously, perhaps?) and alonzo church producd alternative theorems
to demonstrate the same thing, but turing's work laid the basis for
computer science, and turing himself became quite active within the
field of early uk computation (the original ACE design is his, and he
subsequently worked on manchester's computers).
there are even such things as "universal turing machines", which can be
given definitions of turing machines and used to solve such problems,
which we suspect led directly on to universal computers which could be
programmed to simulate special purpose devices.
the "infinite tape" idea is as important as you suggested, however.

Today's haul...
TWO Aquarius II computers (Serial numbers 8 and 10)
Lots of software for the above (cartridges/ cassettes)
box of 10 disks for the Aquarius drive (no drive, alas)
teletext software/cartridges, several modems for the above
Printer for the above
Two tape drive units
One prototype smart card unit (credit card size card) - for videotext access
Prototype Commodore disk drive interfaces (2) for Aquarius
Schematics and manuals for Aquarius
Extension interface
Prototype 16K RAM unit (functional)
OSI superboard II with homemade case, including voice synthesis add-on
Another good day.
I'll be trading at least one of the Aquarius II computers, probably.
Offers?

How about 1130, 1401, 7090, 4300 series? And the ancestor of
the powerPC, what was it, 801?

I have [music] CD's going back to the mid-80's. They all work fine.
(P.S., never buy an Aiwa CD player.)

"Personal Computer Word Processor" I have book 1 of the "User Guide - CP/M
Logo & Word Processor Manual". Seems like it came with "LocaScript" a WP,
DR Logo, and CP/M Plus. A pretty interesting looking machine, actually.

Not exactly "straight". Semi-compatible, iirc. Very early in the PC
timeline, and probably pretty significant.

Could be an AT&T 6300; I seem to remember Olivetti and AT&T worked together
or something.

Well, depends on your interests. If you're interested in PC (i.e., Intel
x86/MS-DOS) history, definitely go for the Sanyo. If you're more into the
older, more proprietary systems (S-100 stuff/CP/M) go for the amstrad. If
you're a Unix/workstation person (Sun, Apollo, UnixPC, etc.) or perhaps
into foreign stuff or something, go for the Olivetti. (Note, I don't
*know* that the Olivetti runs Unix or anything, just a longshot possibility.)
Me, I'd probably go for the Sanyo first, then the Amstrad. The amstrad,
btw, came with a printer.

I have one of these manuals, with some waterlogging, if anyone wants to
avoid UK shipping. Cost is $.55 + shipping from San Francisco. (that's 55
cents, which includes a 1 cent profit. I'm gonna be rich! 8^)

CD's too. I saw a guy pull a stack of 15-20 CD's out of his pocket, no
case or anything, and start shuffling through them like a deck of cards.
Picked one out, put it on the seat beside him, took the CD out of his
player, and put it and the rest back in his pocket.
I guess they still worked (though his player had a (I think) 10 second
buffer, so it has plenty of time to do retries.) 'course he didn't look
like the sort of bloke who listened to anything older than a week.
