Where can one get HP 10529A Logic Comparator modules?

I made sort of a dumb impulse buy off Ebay the other day which was a HP 10529A logic comparator, and I'm saying perhaps dumb because I didn't look closely enough to realize it needs modules in order to plug chips into it which it doesn't include, I paid $50 for it.

So are they available anywhere, can they be made from scratch or am I stuck waiting for some to turn up on Ebay or buying another complete kit?

This of course assumes the damn thing even works as it's untested and I haven't actually gotten it yet.

I have only seen them sold with the comparators.

There are two types of cards for these. One type allows you to hard wire a card for one chip type. The other has a zif socket and dip switch banks, so you can just pop in a chip and configure a working card for whatever chip you have. These are really flexible, all you would need for occasional use.
 
It looks like it has a card in it. Is it a fixed reference card (soldered chip)?

Well here's a picture of it open, I don't actually have it yet so I can't tell you for certain (should be arriving on Wednesday), I was assuming that it plugged in to the side with it open so I thought it didn't have any modules, but maybe I'm wrong?

I don't suppose I could be so lucky that schematics of the modules are in the manual? I've seen a pic of the ZIF module and it looks pretty simply with no custom parts, just the socket, dip switches and a ton of diodes so in theory it wouldn't be hard to repro.

Edit: I've included a pic of one of the missing modules.

Sorry, I am not going to be a big help for you tracking down where you can find replacement boards other than to say eBay.

Yeah, your second picture is the all in 1 board that takes the place of a bunch of reference cards. To me it looks like there is still a reference card plugged in the tester in the picture with the drawer open. It is easy to open it up and still have a card stuck in it. Unfortunately, it just looks like a reference card for a single IC and not the self test card or the all in 1 card.

If you end up getting another complete setup on eBay I would be interested in buying any other single IC reference cards from you if that helps offset the cost.
 
It should have come with a "programmable socket card" (the one with a ZIF socket and DIPs - the only one you really need), a self-test card and possibly some reference IC cards. There is a compartment in the lid of the case, maybe there are cards stored in there?

The schematic for the programmable socket card is in the manual supplement: http://cp.literature.agilent.com/litweb/pdf/10529-90007.pdf
 
comparitor...

You beat me to it. Guess you emailed the seller after the auction ended to buy it? I emailed him to but he didn't respond...

Yea reference cards would be helpful but as long as you have the main one with the adjustable dip's you are good to go.
 
I have one of these, including the bare cards for it.
I will PM you about it.

A lot of people will want them. I don't even have the comparitor and I'd want a set...if cheap enough. :0)

Hi there!
So people are interested in these boards? Just confirming.
If so will look at laying out a gerber file this week and seeing about having them printed off. Its a pretty basic board. I think the idea on them is to solder in a chip, i was thinking it would be handy having a few with different sized sockets so you can just plug in the chip you want to test with.

Could you do a PCB for the programmable one with the ZIF socket and dip switches?
 
Yep, that one! If I understand it right that one can pretty much be adapted to do all the chips, right?

As far as I know yes. BUT i have not used this unit yet, so really dont know alot about it. Bought it with a Logic Clip, and Logic probe and the boards in a set.
Its a tool i plan to use, but havent gotten around to it yet.

Maybe someone else can answer that question better then me. If it is a universal card i can look into whats needed to make them.
 
the one with the dips...

Thats the main one you can use for all chips the unit tests. Trouble is you have to flip the dips for each kind of chip. Those other boards just make life easier but really the dip one is all you "need".

Thanks for that information!
I think i will look at laying out the bare boards into Gerber and then look at whats needed to make the other board with the dip.
