Lots of folks are asking for simple "adapters" for things like:
* older 24 pin EPROM to 28 pin JEDEC EPROM
* daughtercards for 40 pin CPUs and such
I have some vintage items like this, and as I look at them, it looks
like they use something similar to a machine-pin socket, but each end of
the pin is the same (small diameter.
The ones I've seen have a slightly thicker pin on the soldering side.
Last time I bought soemthing like this, it came as a 32-pin SIL strip. You
cut off as many pins as you needed and soldered them to the PCB. To fit a
DIL socket you'd cut off, say, 2 lenghts of 12 pins and solder them to
the PCB the appropraite distance apart to fit a 24 pin DIL socket. I
found that inserting the 'plug' end of the pins into a turned-pin DIL
socket kept them at the right spacing when I was soldering them.
I think I ought them from Farnell. Maybe RS components. I don't recall
having any prolems finding them.
