1980's trip computer?

[missinglink]

Hello everyone,I was advised to ask here aswell,from a fellow forum user in the Electrical section.
The trip computer has a connector on the back,which I have now been informed as an edge connector (thankyou Gunnar). As the OE connector are rare,would there be possibility to advance on the connector. I'm thinking maybe drill a 0.5mm hole in each track and solder in,another type of connector?

thanks in advance
Paul

it is probably worthwhile measuring the connector - how many pins over what distance, one-sided or two, etc.
And how thick the board is, if it is two sided.
Then maybe you can figure out what connector it was, and if someone sells them now.

Do you have specs on the device, or are you going to reverse engineer it, or what?

And why?
For a nav computer to be useful, it needs current maps. And maps are configured according to the software that will use them.
(surprise!)

Thanks for your reply. I've managed to open up the trip computer,and take photos of the pcb,to see if it's possible to mount and convert the (beige area with silver tracks) board with a more ready available connector,as appose to the OE connector. You see,what happens is,when someone breaks the vehicle up for parts,they sell the computer without the connector,which makes no sense. As you can see in the photo with the OE connected,it shows 7 wires across and one below,which may cause an issue.
I hope this gives you an understanding

I guess you could cheat - use a card edge connector for a closer connector spacing, and just wire the connectors that happen to line up?

Lots of old PCs and other electronics used card edge connectors. Lots to choose from.
Do these carry a significant current?

The suggestion of using a higher density edge connector is probably the cleanest solution, overall. Alternately, you can simply find another set of connectors with at least that many connections, and pigtail the mating connector to the board by soldering directly on the edge connector.

Of course I can. I can do anything. I can do absolutely anything. I'm an expert!
