I'm down to the last few P112 boards for sale and am pondering another run
of them because demand is steady. One of the biggest challenges for the
last run was getting the QFP-packaged 100-pin chips[1] in a state such
that the pick-and-place robot wouldn't throw a fit about slight
differences in lead position. The stuffing house insisted that I send
them new chips. Pulls, though they looked perfectly okay to me, were not
acceptable. Does anyone here know anything about pick-and-place robots
using pulled 100-pin QFPs, particularly a stuffing house that can work
with such chips and not screw up?

I'm trying to identify the specific unit. It looks like an early PA-RISC,
but even the enlargement doesn't show the model number clearly.

May depend on the model, but mine has a spring under the plastic reset button in the top of the case and one of those metal domed tactile switches on the PCB.

This series of articles focuses mainly on physical design, of cases
and so on, but there are some technical details in the articles too.

I am about to get a large batch of RK05 packs, so I am interested in the
details of this.
First, what is 'burning spirit'? (I assume this is a straight translation
into English of some German term, but not knowing German... :-) After poking
around with Google for a while (hampered no little by the fact that it's the
name of a band, and also a term in World of Warcraft :-), it seems like it
might be acetone?

Hi folks!
I recently acquired a functional Sun 2/120.
The framebuffer I have is switchable between TTL and ECL, so I can use
either an Sun 2 or Sun 3 monitor, which I am looking for.
I am also looking for a keyboard and mouse.
If anyone on list has any of these items and would be willing to sell them
to me, please contact me. I plan to completely restore the system.
Thanks,
- Ian

Hi,
I just saw that mails from some people now arrive as desired (real
sender, reply-to list), but some (e.g. myself) are still mangled with
"xxx via cctalk" - did I miss a setting?
Confused...

Can anyone who's been inside an Intellivision confirm that there's supposed
to be a little foam disc beneath the reset switch plate?
I picked a system with a box of cartridges up earlier, half expecting the
machine to be dead (I was figuring it was going to be a blob of
easily-dead-after-so-many-years custom logic inside, but it's more like a
"real computer" in nature). It *was* dead, but the [initial, at least]
issue seems to be that the reset switch consists of a metal plate which is
supposed to make contact with the PCB when pressed - and presumably is held
away from the PCB by something when at rest. Except that there's no
"something" in this machine - with the machine the right way up, the plate
is free to contact the PCB, holding it in permanent reset.
I'm guessing it was a blob of foam, which has deteriorated, but maybe it
was a metal spring, or a piece of u-shaped plastic etc.
cheers

This card is sitting in a IBM RT PC.
http://i.imgur.com/Adqnxr3.jpg?1
What kind of card is it? The WD1935 seems to be a SDLC chip. I cannot find
any reference to the numbers P/N 6247874 (bottom layer etch) or the number
on the sticker on the backside: 6247871G001
It is connected to an IBM marked dongle which has 4 BNC connectors.
Is it a 3278-3279 emulation board?
