Replicating IBM SLT/MST card interconnect

[Tom Stepleton]

Hi cctalk,

I'm looking to replicate the 24-contact connector system that IBM used on
SLT and MST cards for many years. Has anyone done this before?

The best photos of this connector that I can find online are on this page:

I haven't searched Bitsavers documentation extensively for IBM
specifications, but I've seen some details around page 54 of this document:

I'm interested in reproducing both polarities of this connector: plug and
socket. Also, even though the most familiar use of this connector is for
board-to-board interconnect, I'm most interested in wire-to-board
interconnect. IBM used this method for DC power connectors in its  5100,
5110, and 5120 computers. Here are images of this specific connector:

taken as still images from a YouTube video on the IBM 5120 by Jerry Walker (

I've designed and built a device that monitors DC power supply voltages for
overvoltage and undervoltage excursions and cuts off all power rails if any
voltage goes out of spec. I hope to use it to protect my own IBM 5100 from
major power supply faults like the one CuriousMarc encountered with his
9825T:

In order to put my device between my 5100's power supply and the logic card
backplane, I need to recreate a plug and a socket so that I can fashion a
cable that goes out to my device. If anyone has created dependable modern
versions of these connectors, would you mind sharing any pointers?

Thanks for any help,
