Were there ever Digikey or Mouser BOMs listed for similar boards?
If not, just double-check your selections before hitting purchase.
I got my u16 PCBs from "jlcpcb.com" in 5 days. (for 6$ incl shipping)
The 1N270 for a reasonable price need a much longer delivery time;-(

I would just use a 2x3 header, i find that i usually never use mine as a Clip function ( when you switch between clip/comp, your have to change all the dip switches anyways. ) so have a switch is pointless IMHO..

So just 6 pins and a jumper instead of a switch? Yeah, that can be doable. I should have enough header pins for that kicking around. Thanks, thats a good idea.
I used a double pole switch only because that was the one I was using for the Vector Test Bench Adapter. Both poles of all three terminals are connected, so a single pole switch or header will work no matter which holes you put it in. I could have picked anything, but happened to pick one that was then discontinued and has unusual spacing. But, I found one that will fit and is still made: Digi-Key-Key part 360-1758-ND. There's also a slide switch (563-1561-ND) but you'd need to cut of the mounting tabs.

Thanks Douglas, I will check those switches out as well. Nice to know I have options.

Hey Glitch! Nice seeing you here.

Hi guys ,
Digimon gave me one of his ordered pcbs (thanks once again) for testing. I also found a shop where I could get the 1N270 Germanium didodes kind of cheap.
But now I tried to test it, the lights are going nuts on the comparator.
Could you maybe see just from the look if I did something totally wrong ?
Cheerio from Hamburg,

Is the main board for the 20 channel comparator still for sale or is that long gone?
Gerbers for the main PCB are now available on the honor system: if you make some for yourself please send me a few bucks. If you make a batch to distribute to others, send me an amount proportional to the number you sell.
What do the 10529a comparators usually go for these days?
150-300 depending on accessories / case, etc.
Cool, and the card with the ZIF socket and DIP switches looks like it goes for about $75-95 so that being included with up the value as well. I need to read up on these.
Keep in mind, The best tool is still a $15 logic probe... i do more repairs with just a DMM, and Logic Probe.. Tools Like the 10529 , Fluke, Logic Analyzer(s), etc, are good to confirm something is bad, but the logic probe will get you 90% or 99% of the way there.
I have a stack of bad GORF pattern boards that I'm thinking a Comparator is going to help out a lot with Id'ing the bad logic chip, especially with how much of a pain it is to troubleshoot the cards in the cage.
Those pattern boards are a nightmare to debug
