HP 10529A

Hello all,

I recently got ahold of an HP 10529A logic comparator but I am not sure how to use it.

The unit came with a self test card and a card with textool socket 10529-60014.

When I insert the test card and supply 5V to the card connectors the logic comparator LEDS blink shortly with a 2 second interval or something. If I also connect the logic clip on top of the "dummy" IC I get a long blink (approx 1 sec) and then still the short blink. I don't know if this qualifies as "normal" behaviour.

To test the 10529A comparator I tested with a Wonderboy PCB. I insert the appropriate 74LS chip in the textool socket (pin 1 aligned to the "1" mark (near the SW error led)) but no matter how I fiddle around with the dip switches or COMP/CLIP switch I always get red comparator LED's to remain turned on (I expected either all of them to light up or remain off). I have tried with different 74LS chips on different locations but I can't get any decent result out of this.

Can anybody tell me how to use this 10529-60014 thing (no manual here) or tell me what I am doing wrong ? A short description of what the dip switches and comp/clip switch are for would be welcome...

Best regards,

Filip
