YMMV but I did a video of making refence cards.
Jacklick, was the list of most common ICs and pin compatible ones in this thread or somewhere else? I searched though a couple of the HP 10529a threads but couldn't find it.

Thanks but my post didn't get much traction so I just bought the stuff I needed and paid the shipping costs. I have a few on the way, and some LS386s to have on had as well.I have stock of L86...

The 74LS386N fixed the issue.Thanks but my post didn't get much traction so I just bought the stuff I needed and paid the shipping costs. I have a few on the way, and some LS386s to have on had as well.
I tried an HD7486P from a spare board I had, but that didn't work. Couldn't find a datasheet on it so I just bent the pins wide (didn't solder it in). It did activate the "dead" LEDs but then other ones wouldn't work so I'm guessing its pin out is not exactly right.
The stuff arrives tomorrow so I should know soon if it's fixed.
