8555A spares
Hi Don, The box with the bits and pieces was delivered to the post office this morning and should be on the way to you. The postage was < AU$ 10.00, so I don't think that we are going to loose any

Re: data aquisition switch
There were several data acquisition boxes prior to the 34970A. The original data acquisition boxes (in the middle '70's) were the multiprogrammers (6940A and 6942A). These had plug-in cards each with

Re: data aquisition switch
Hello Paul - It is the 3497A and there are manuals etc on the Agilent web site. I have a number of them along with most plug-in cards and an enormous amount of hard copy documentation for them.

Re: Looking for an 8640B manual
I just noticed that Manuals Plus is running a 50% off sale on their original hardcopy manuals (not reprints). That makes some of their more-expensive manuals and sets a lot more affordable. -- john,

Re: was HP 5342A board, now IC sockets vs soldering
A little off topic: In the 1980's, I worked at a company that had a policy of putting all IC's in high quality sockets. This came in handy because some of the techs didn't really know how to

Re: was HP 5342A board, now IC sockets vs soldering
Yes, its a tough call either way. FWIW, when I worked at Tektronix some 25 years ago they had an internal design interconnect handbook that recommended against IC sockets if at all possible. Their

Re: HP 5342A processor board
I would replace a supect socket with a good quality one rather than solder the IC in. If the IC is bad, it just means more work and possible damage to remove it again. -Dave

Re: HP 5342A processor board
Good point, I guess with 20 years old gear, you are not worried about having to upgrade the software :-) I am seriously thinking of doing that with my HP 5370A if the problem comes back. Alternately,

Re: HP 5342A processor board
Jim, There is a possibility that one of the ROMs might be bad. You may be able to get the code from Blue Feather Tech and burn new ROMs. If the CPU is getting it's clock and the reset is good, you

Re: HP 5342A processor board
Many years ago with microcomputers which came with low quality sockets, I had an assembler remove the sockets and solder the ICs in directly. That eliminated intermittent crashes in some 24/7

Re: HP 5342A processor board
Jim, Have you tried the obvious of pulling and re-inserting the CPU and ROMs (and any other chip on socket)? My 5370A has needed that treatment at least 3 times, in spite of Deoxit ProGold. Each time
