Hi Ken, I don't know if it helps but there's a 43/86 edge connector offered here for 14USD, (12USD for 5+)...... https://www.surplussales.com/ComputerAccess/con_edge.html Single and double sided PCBs with 0.1 inch spaced strips were quite common at one time as part of the Veroboard range, some with gold plated edge connectors and some quite large, and it's possible these too might turn up as surplus. Not ideal for taking the double sided connectors but easy enough to bodge, albeit a bit time consuming. I thought I had some of the larger boards amongst my old prototyping stock but can only find 32 way single sided at the moment so the others seem to have gone already.

I know what the extender looks like as I found one on ebay several months ago that had already sold for $50 (damm it!!) and I have been looking ever since, but it had a picture of it. It is a double sided pcb board that plugs into the female connector that is mounted vertically in the instrument and then rises up above the top of the instrument case where there is a female socket mounted horizontally so in effect the board now sits horizontally above the instrument whereas normally it sits vertically in the instrument. That way you have access to the board to take measurements, something you cannot do when the boards are in the instrument due to the close spacing of the various boards. As the 43/86 pin card edge connectors appear unobtainable I have sourced a 50/100 pin female connector that I can make do with, but I need either a 43/86 pin male card edge connector (which are also unobtainable) to make up an extender using cables as you have done, so the only option appears to be to make up a double sided pcb board with pads spaced at 0.1" centres on both sides and then either use it to terminate the cables to the female socket , or probably better make the pcb the same as the original extender and just use my 100 pin socket on that. That is why I was hoping someone may be able to photo copy the pcb board if they have an extender they do not want to sell.

Hi Ken, Nigel is setting you on the right track with Vectorbord. I have used them for the edge connectors over the years with good results. I don't know if you are able to use Digikey of not but they list a 3690-26 ($80) that will be easy to modify to work for your project. I probably shouldn't have said that since I dont know how long you need the card extendor to be. If it is long enough it is not hard to saw (or mill) it twice to get the proper number of pins. I have a small mill available so I would use it. If i had to use my table saw it would be more of a challenge but it can be done. I usuallydon't need to glue the connector since it is largely self supporting. If it is a bit too loose for you it is easy to glue a plastic strip or two on the connector face. If you really screw up the connector you can replace it with the one Nigel found. Just use heavy wire wrap wire for any "Adjustments". There are a few Vectorbord choices that would work for you. By the way, although Vectorbord is the correct spelling it is commonly spelled Vectorboard on the net.
