Above my eBay purchased E card on my homebrew extender solution.

Like a lot of SB-104 owners, I did not have the card extender that shipped in each kit. The extender is needed to raise the cards out of the card cage so that signals and voltages can be measured. The original cards and even replacement kits go for over $50, and I didn’t want to spend that kind of money. My solution was to use .093 Molex pins which I purchased from Mouser for around 12 cents a piece. Four inch number 12 wires that I harvested from a roll of Romex cable were used. A male connector was soldered on one end, and a female on the other which provides a set of extenders for about $6.00!  24 extender wires are needed.

I put all the wires in the cage, then start at one end of the board and work the wires into the board’s connectors. I alternated the black and white wires to make it easier to insure that I did not cross any wires. An added advantage in using the wires over the original extender card, is that a particular wire can be left out, breaking a connection during troubleshooting if desired. A board extender of some kind is a necessity when working on this kit.
