Bob,
I'm not far away, Maybe I can help. FYI I have NO data on the tarbell
controller but if the disk is standard SSSD I can help.
No interest in the HP or symbolics though, too far off my collection.
Allison

Hello, all:
I posted this question to ChipCenter a few weeks ago, but I've
gotten no responses. Where can I purchase PC/104 stacking connectors in
really low (single unit) quantities? My usual suppliers DigiKey, Mouser and
Jameco don't carry them. I'm checking Pioneer Standard and some of the major
supplier houses, but has anyone actually purchased these for prototyping
purposes?

You can no longer directly email a buyer or seller but have to go through
Ebays intermittently working email forwarding system, the requirement to use
Active X in order to use their new photo hosting service, the sellers page
requires javascript unless you have the old page bookmarked or go through a
two step process to get there, the addition of the BIN (Buy It Now) feature,

grrrr, it sucks. I have to clear out all kinds of javascript errors running
my favourite netscape 3... I really miss the option to directly email
sellers. Good deals could be made that way!

No, an 11/53 processor is an M7554, which is a quad board with J11, half a
meg of memory, 2 SLUs, bootstrap, etc. It's rather like an 11/73B but with
added memory (and no PMI capability, I think). It was designed as a low
end system, and IIRC it's slightly slower than an 11/73.
If you saw 11/53 BA23's with 11/23's in them, someone swapped the cards, or
swapped the labels.

Anybody know the voltage tolerances for S-100 bus computers, or where
such info. can be found? I am preparing to run a 1981 vintage, 19-slot
S-100 system.
After pulling all but one of the cards out I powered up the system.
Fans run fine, but the motherboard voltage supplies are rather high. For
+8V I measure 10.7V; for +16V I get -19.3V; and for -16V I get -19.3V. Is
this some careless engineering, bad components, or is the board really NOT
supposed to receive the nominal voltage?
Many of the S-100 boards are discoloured brown-green on the solder
side opposite these large transistor-like things with heat sinks. Is that
something to worry about?
I also measured the DC voltages of the pins of one of the slots. This
is what I got (assuming that pins 1|51 is at the power supply end):
volts pin# volts | volts pin# volts | volts pin# volts | volts pin# volts

Does that look safe enough to put the boards back and see how this system
runs?
A fair amount of current runs through these slots. I nearly welded my
probe to the slot when I accidently shorted two pins!
Any help, encouragement is much appreciated!

That's why they changed it! They refused to consider the benefit
it was to *users*-- only that they figured that it was taking money
out of their pocket!

Actually, when I was working for a company in Sydney (when the PPC512's
& PPC640's came out), we did manage to interface a drive to 'em, it's a
*very* tight squeeze, but you can fit them in.

I can't, and won't, speak for Allison.
However, from conversations I've carried on with her in the
past, she likes, as do I, the "in-band" method of replying
to a pervious poster's comments, like I'm doing now. Of
course, since the only part of your message I wanted to
reply to was the snippet above, this message isn't a good
demonstration of what I'm trying to say.
Anyway, it's easier to intersperse my replies with the
original comments- I do not like the way many people
just stick all their comments either at the top or at
the bottom of a message.
Now, if I reply to an HTML-format message and intersperse
my remarks with the originals, and FORGET to convert from
HTML to plain-text before I begin, some people will see my
post and see only the quoted original, and won't see my
replies unless they want to wade through the HTML-ized
version of it.
If we were all just posting manifestos, Allison and I
might not object as much as we do. But we're trying to
carry on conversations, and I simply think plain text
does the best job of carrying that conversation.
I live for the day when Outlook or Exchange allow me to
simply establish a filter that strips all incoming mail
of any HTML....
Regards,
