I'm not familiar with that other measuring system...

To think that I didn't think of that!
Oh well, here's just something which happened to be in my browser at the
moment, on a related topic. It's about making an adapter for running Japanese
games on Western SEGA Master Systems, which involves a card-edge connector.

The Japanese connector is a 44-pin one of a very unusual pitch (0.125inch I
think), which is very difficult to get hold of. I did find one company which
manufactured them, but I'd have had to buy 1000 of them :-(
I made my adapter by cutting (hacksawing) a standard 50-way 0.1inch connector
into segments of six pins each, with four pins on each of the end segments,
kind of like this...
__ ___ ___ ___ ___ ___ ___ __
| | | | | | | | | | | | | | | |
|__| |___| |___| |___| |___| |___| |___| |__|
|| ||| ||| ||| ||| ||| ||| ||
Note the gaps in between each segment. One of the middle segments was
discarded (50-6=44) and the remaining ones separated and glued in position on
a standard SMS cartridge shell. Then the connector pins could simply be wired
to the corresponding points of the cartridge board (the ROM having been
removed). The whole process was very tedious, but the resulting adapter does
work (thankfully!)
