While oogling all the pretty Apollo pictures at
http://www.citi.umich.edu/apollo-archive/photo-gallery/ , I found two puzzling
pictures:

They're described as a "Token Ring Remote Network Switch (RNS)", but then what
are all that coaxial wiring doing there? All TR which I've encountered has
been either TP or those frightening IBM connectors.
What is the meaning of all this?

JavaScript has been developed to show scrolling messages on your pages. It
should have been named ScrollerScript, but as it came out more or less the
same time when the hype on a programming language called Java (poor man's
SmallTalk raped by C++ which is expected to solve all problems of the world,
including traffic, pollution and AIDS) started, it's creators decided to use
the term ``Java'' in it's name, too.

Hello out there,
does anyone know where I can get hold of information on the follwing old IBM
products
(manuals/microfiche etc)
products
-----------
5798-AXC
5796-AEF
manuals
----------
SH20-1358
G320-8088
SN20-6277
When where the first 74xx ICs released / designed ?
Especialy when where complex chips like 744x, 748x or
74181 first mentioned/available ?
This may be a stuipd question, but I couldn't find any
information ... so all I have is my personal guess (~1970)
and the oldesd TTL book Philip Belben could find (1972).
Anyone more informed ?
Gruss

It existed in 1970. By 1973 it was widely used. My Yasu Freq counter
(good to 350mhz) was purchased in 73 and contains:
7490 decade counter (usually good to 35mhz then)
7475 quad latch
7441 Decimal decoder and Nixi driver.
7400
7404
74Sxx parts were a year or two later.

Hey I just felt compelled to make a joke.. and keep in mind it was like 1AM
my time... Is there a SNAFU register as well? Just wondering... I need to
have SEX with all my Interdata's/Perkin-Elmer's... heh, thats the "System
Excerciser"

I've not had the time I hoped to sort through my FDCs* and pick likely
candidates for 8" operation (and SD for 5.25" as well), but I do want to
thank Tony, Allison, Don, and everyone else who provided useful
information.
* Partly because I spent most of the weekend repairing two 8" drives -- one
of which was only bust because of my own carelessness :-( -- and sorting
out surplus equipment which I'll offer to the list in due course.

As stated before, this is a just a daisy-chain ring type network (that
is, the
ring is both physical and logical) that operated using a token-passing
scheme.
It was proprietary to Apollo as far as I know.
I've got a few of these cards laying around, unfortunately without
machines to
go with them. They're full-length ISA-bus cards with something like a
6W2 (six
pins and two BNC-type connectors ala a 13W3 monitor connector) that one
would
connect a small dongle to. The dongle has two BNC ports on it ("in" and
"out").
Interesting stuff...

Oh yea-- that's the same stuff they use in Hospitals, right?
I always wondered why they all smelled *exactly* the same :^).
Isn't that stuff usually allowed to 'wick out' a cotton
pad stuck in the bottle?

I'm interested in the exact same thing you are at this point. I'm workin on
a 6502 board, i hope to have it finished soon, i may put some schematics on
my web page. For info about the 6502 and projects, you cannot beat
http://www.6502.org, Chris Ward's 6502 board in particular. For 6502-related
books, the best i have found have been Programming the 6502 and 6502
Applications, by Rodnay Zaks. Keep an eye out, they may show up on EPay if
you're lucky. As for the processors themselves, I recycled my 6502 out of an
old 1541 disk drive that didn't work, and i recently found a Z80 in a PC/AT
keyboard i cannibalized (albeit for the LEDs, how ironic). Anyone else out
there have any advice/suggestions???

I just got an external Infoserver 1000. Can
anyone provide the pinouts for the power
connector, or even better, does anyone have
a spare power supply?
