I posted some photos on alt.binaries.schematics.electronic.

There are two of them on a '79 Porsche 928 Central Warning Computer.

My CWC is starting to get a little flakey. It monitors numerous analog
inputs, including various lamp currents and illuminates the central
warning idiot light as needed. Mine is starting to generate phantom
alerts. Based on the make (Porsche) and age, a replacement is probably
going to be expensive, so I'm going to attemt to roll my own. Partly for
the fun of it as well.

Well, Paul, You know the standard answer on s.e.d, use a PIC ;-)

I love to cook with wine. Sometimes I even put it in the food.

...or a 555. (or was that last year's solution?)

No smiley needed. That's what I had in mind.

I can get better data from the analog inputs to identify intermittents,
bad input data from transducers that have gone t/u and log events with
time stamps.

When the PIC fails its time to get out the 20 Lb sledge. ;-)

Hello Paul,

> I posted some photos on alt.binaries.schematics.electronic.

This post didn't seem to propagate into the Pacbell server so I can't
see it. But I see mainly two options:

Get connectors in better shape or maybe even a whole CWC from a salvage
yard.

Contact distributors in Germany who might have such connectors. Example:

http://www.deltrona.de/

Or look closely whether there is a logo from Panduit, T&B, AMP or
whatever somewhere on the shells or inserts. This might require a really
strong light. Finding ever so faint logos has helped me more than once.

Another thing I found when driving a really old Ford Cortina in the UK
was that some receptacles need a slight bending inwards to create a
stronger contact force. Else I'd still sit on the road to Durness ;-)

Regards, Joerg
