Hi, I'm a great believer in archiving EPROM's but in the last instrument I worked on they were soldered in place. I wonder if anyone had successfully read the...
determine the output enable or chip select line, cut that track - drive it from an external eprom reader clipped onto the device, you'll also need to stop the...
Hi Joe, Yes I could read the PROM from several instruments (HP & non HP) although they where soldered (not socketed), however I've been obliged to desolder all...
... If the processor is in a socket, then remove the processor and piggyback the wires in. If the processor can be turned off and tristated, you might be able...
... I would make up a little jig out of a microcontroller with enough RAM and a nest of wires-with-clips (source: old logic analyzer pods). Many, if not most,...
You can do a couple of things: Use a logic analyzer on the address and data busses and assemble the EPROM contents from CPU reads. This is a lot of cut aqnd...

Does anyone have a cross for this? It's not in any of my cross reference pdf's. It is located on a 5335A location A3-Q6. It is marked (S shaped logo) 550300 ...
Hi Guys! I am looking to get a better function generator than what I presently have and wanted some recommendations for decent models of HP generators. The two...
It's good to have both a digitally-controlled generator and a cheap analog job, for the same reason that your 8657A doesn't replace the 8640B in every ...
Chris, The 3325 really is a very stable, low distortion, low noise signal generator that happens to also provide square and triangle. It's not what I would...
Thanks Didier and John, I guess another way to put it is I don't need the 3325 if it is just going to be a glorified low frequency RF generator since I already...
Just a note to the board. I recently bought a couple units off ebay and one had no manual sweep or step functions. The problem was a burnt out grain of wheat...
... Hello Pete, I don't think this is right. The schematic of the 5335A shows A3-Q6 as a NPN type. The parts list states only that it is NPN SI TO-92 rated at...
OK, I took a shot at the numbers in your earlier post & guessed wrong. But, I do have several pieces of NOS 1854-0636. Is this what you need? If so, please...
Hello all, I've recently bought a HP8620A with an X band plug in. I've tried the HP site for the 8620A manual without any luck - can someone point me in the...
Rich The manaul on Diddier's site is for the 8620C ... We have the manaul for the 8620A if you dont find a free one. Contact us off list for further details at...
Do you mean a Harmonic Wave Analyzer 300A? That is a real oldie from 1941. I would love to have it, but it would likely cost a fortune to ship to NJ. Is this...
I may know of one in NE if you want it let me know and I'll see if it is still available. Nice condition last I saw it. Paul ... From: Mike Sloane To:...
Does anyone know where I can obtain a PDF copy of the service manauls for the HP 8662A? Â I also need a replacement power supply card for the 8662A, if anyone...
Yes the first ! The case is wood and the part in the worse shape is the case. Someone started to restore the case but on got to filling all the holes and...
