WTB S100 connectors
I have a need for two S100 backplane connectors. Drop me a note off-list if you have two to spare. Thanks. Mike Loewen mloewen@cpumagic.scol.pa.us Old Technology http://q7.neurotica.com/Oldtech/

What spacing? Obviously 0.125" between contacts, but what about across the other way?
Ditto. I have some that are NOT correct for IMSAI, MITS or Cromemco (BlitzBus anyway). Bill S.

It's hard to get an exact measurement, but my digital caliper says spacing on center is somewhere between 0.285" and 0.290". These are for an SD Systems Z80 Starter Kit board. Mike Loewen mloewen@cpumagic.scol.pa.us Old Technology http://q7.neurotica.com/Oldtech/

Yes, it is. I don't have mine at hand, but does it look more like this: http://www.vintage-computer.com/images/mits4slotmbbot.jpg (Narrow spacing) Or this: http://vintagecomputer.net/Morrow/view_power_voltage_labels.JPG (Wide spacing) Bill S.

Apparently I don't know how to read a caliper. It's more like 0.250". Mike Loewen mloewen@cpumagic.scol.pa.us Old Technology http://q7.neurotica.com/Oldtech/

There are two different Row spacings out in the wild. As Bill showed here already. I recall the wider spec was originally intended for wire-wrap backplanes, but they also sold the solder pin variety. This place has the the skinny variety . It's become a popular source for the retro projects in the S-100 group. I used them to make another of their retro backplane projects . Th is say s it's 0.24" Row spacing , only $3.95 http://anchor-electronics.com/product/100-pin-125-inch-card-edge-connector/ Dan

Thanks Dan, but I've determined that it's definitely the wider (0.250") size. Mike Loewen mloewen@cpumagic.scol.pa.us Old Technology http://q7.neurotica.com/Oldtech/

I thought the wider row spacing was even more. I don't have this type here, maybe Bill can measure those he bought the other year. and I think that was a typo on Anchor Electronics, either 0.24" or 0.25" was the skinny variety Dan

According to this, Altair uses 0.140" row spacing and IMSAI uses 0.250" row spacing: http://www.s100computers.com/N8VEM_Archive/msg01180.html Mike Loewen mloewen@cpumagic.scol.pa.us Old Technology http://q7.neurotica.com/Oldtech/

oh yea, I should've looked inside my 680 again and noticed the difference :)
