Does that little gadget have a boost converter to generate the +25V?

I was surprised what good value it was. The software disk installed effortlessly (on my HP computer running Windows XP), And it has...

Hugo, knowing you, you would not have stated this unless you have used the GQ-4X with the 2716 and the 2532, the EPROMs needed for pin...

Then perhaps consider using a 2816 EEPROM rather than a 2716 EPROM. Assuming you can find an affordable part from a GB source as they...

Bow, I just noticed said you don't have a programmer to program the 2716 or 2516 which takes a programming voltage of 25V. An old...

Gary, That is correct, but note that the /Reset signal is not inverted (the 7417 is a non-inverting buffer). The /IFC is also a LOW...

One of these days, I suspect someone will open a long-abandoned crypt and discover a cache of all of those logic analyzer pods that have...

I've seen how this stuff gets disposed of. The instruments are stacked on a pallet. The cables/pods go in a big box. The pallets get...

Haven't bought stuff recently but can give a little info on things to investigate. Name brand older equipment can have better...

This is a very important point with old logic analyzers. The prices can look very affordable, but without all the cables, pods and...

I did not know this. Thanks for the info. My version of WinCUPL only runs on very old Windows like W98 or 32 bit versions of XP and use...
