Re: Need transformer for 70004A Power Supply
Nice work, and also a very nice webpage. Thank you for sharing this with everyone. Also, an EXTRA thank you for sharing in a way that is easily accessible to everyone. It¡¯s getting a little tiresome to have to be a registered member of this group or that to be able to see something. And the ¡°see us on Facebook¡± thing is particularly nauseating. Your web page is a breath of fresh air!
Cheers! Doug |

5303A is missing unknown IC...
I have a 5303A counter, which is missing IC6. See Photos.
Can anybody tell me what this IC is? If you have a 5303A, please have a look. Photo? Rest of the counter is working OK, just this unknown IC missing... A schematic or manual would be very welcome! Thanks & regards, Gertjan Miedema. |

Re: HP Rack mount, 5060-0174
¿ªÔÆÌåÓýI have five 84 inch tall 19 inch ¡®telephone racks¡¯.? These are constructed with two 84 inch long about 2 x 4 inch aluminum U channel with four 4 x 4 L brackets, two at the bottom and two at the top.? I built bases out of three 2 x 6 studs, placed flat, about 30 inches long, with ? inch plywood ¡®screwed and glued¡¯ to the top and bottom at the studs.? I mounted extra heavy duty casters on the base and bolted the ¡®racks¡¯ to the base.? Supports several hundred pounds each. ? Joe ? From: hp_agilent_equipment@... [mailto:hp_agilent_equipment@...]

Re: 5328A gate
The only problem that I have had with my 5228A was a dead TTL logic chip on one of the plugin boards. I forget the symptoms of this, but dead counter springs to mind.

Of course the offending device was obsolete TTL; so I dusted off Boolean logic, and de Morgan's laws (unused for decades) and wired in two piggybacked TTL chips that were not obsolete to simulate the dead obsolete one. Peering at the schematics it *could* have been A4U10 on the function selector board, labelled Time Base Multiplexer, a 74S64N. No guarantee - it was a while ago. It looks like they can be got now from obsolete old stock, eg Of course that might not be your problem. Craig PS and replaced the power supply electrolytics, which were smelling like cat urine and clearly dead or dying. -----Original Message-----

I have manuals 05328-90076 and 05328-90011. Manual 05328-90076 has a table 4-1 "Performance Tests". Step 1 is self check and the counter fails this test. The only things that work properly is the resolution moves the decimal point correctly and the reset illuminates all segments of the display and all of the annunciations. The gate light will illuminate during reset, but will not illuminate during any other mode. What manual number are you referencing?

Re: HP Rack mount, 5060-0174
I was concerned about that myself.
Are real racks really that difficult to find? I mean, I may be an outlier here with close to seventy of them in this building, but still. I see them on Craigslist, at university surplus stores, in govdeals auctions.. -Dave On 10/26/2015 11:15 PM, Merchison Burke merchison@... [hp_agilent_equipment] wrote:

Re: HP Rack mount, 5060-0174
¿ªÔÆÌåÓýHello,I don't see any horizontal cross-pieces or rails to prevents the 1" x 4" vertical pieces from bending away from the equipment (under the weight) or preventing the frame from twisting; breaking and dropping all your equipment onto the floor? To me, it does not look safe. On 2015-Oct-26 5:40 PM,

Hard drive compatibilty for hp 16700a Logic Analyzer
I need to replace the 4.3gb hard drive model st43s011 (quantum fireball scsi)
I think I can get a st43s012 which is the same capacity but slightly different model number. Anyone know what drives are compatible in these logic analyzers? Is it possible to go with a bigger drive? |
