Re: First Gen HP 54810A with dead HD, Got ISO 3.5, Any way to write it to a drive?
HP54810A first gen non VIN?
Recovery to Win 95
That was a bit of a hassle, mostly due to my own incompetence.? I'm a PhD in Mechanical engineering with a specialty in tribology. I know a whole lot more about the high shear rheology? of the PFPE fluid used on the hard drive than how to make them talk to a PC. :-)
I will write up some key leanings here that might help someone else the way you guys helped me.??
Thank you so very very much by the way!?
1: In my case I was not able to connect with it using USB or mini din adapters. Did not matter if I went from DIN to miniDin? or if I did DIN-MiniDIN-USB. Once I borrowed a real old dirty keyboard from a junk pile at work I was able to connect and get into the BIOS.
2: A standard WIN98 SE boot disc was not able to connect to a 24X DVD Rom player with IDE I found but once I found a old CD player from around 98-2000 i could connect
3:? I was not able to get it to work with? the plug in board connected to the primary port and the CD ROM to the secondary. ? The scope will not connect to anything on the IDE ports until I changed the BIOS settings. The default settings is only recognizing the installed drive but after going down the list and set Pri Master to AUTO? ? and Pri Slave to CD ROM and make sure the jumpers are set right on the drives it booted up and it recognized the drive and assigned D: to the CD ROM.?
I connected a 5.25 drive and the CD to the PRIMARY IDE on the board without including the plug in board since I did not have a 40-44 IDE cable
At this point it looked like I could have been able to install the system on the 5.25 and then use Macrium Reflect to clone it over to a 2.5" drive once I had a working HD.? Alternatively It might have worked with a 44-40 pin IDE adapter? I was a bit impatient and did not read up on how to use Ghost. I got ABORT: 10180 Bad GET_PARAMETERS: 1 when typing ghost at the prompt.
At this point I decided to take a second look at the image I made using Macrium of the original drive.? I thought it was going to be corrupt but worth a try so I cloned the original disc image down to the 5.25" and it booted up and worked on it!? Then I simply hooked everything back and put a 2.5" IDE in with the same image and after resetting the BIOS (Auto on Pri IDE, not installed on secondary it booted up just fine!
Yesterday I got a "Mustpoint? SD SDHC SDX MMC Memory Card to IDE 2.5" 44 pin Male adapter converter "? from Amazon ($14.59) plugged a 8Gb SD card in it and used Macrium to burn down the image onto that and it worked perfect!? https://www.macrium.com/reflectfree
Again,? Thank you so very much for your help. Is there anywhere I can archive the disc image for someone else in the future having the same issue?? With the image it would be a 40 min job to burn it on a IDE-SD. The image is only 191Mb
For now I put up a copy of this text and the image file? on google Drive
Here is the imaging tool:
https://www.macrium.com/reflectfree
?
? ? ? I do have a disk outside the machine so if there is another free imaging tool that is more future proof, please let me know.and I will make another image and store it. Stay safe!? Yesterday I got a? ? ?    "Mustpoint? SD SDHC SDX MMC Memory Card to IDE 2.5" 44 pin Male adapter converter "??

Back to the topic, so, OK, I can get a bottom section and interconnect cables. Any ideas what I should pay for it? Again, non-matching, no cal data. Could be fun. OTOH, the system could weigh a lot less. :) Got the top section for $200 US.

I will say that I love my 3588A, just wish it was a bit faster. :) Oh, and I wouldn't part with my 54542A for anything.

Mine has never needed calibration (empirically...it agrees with a few other instruments here which have been calibrated) but surely we can figure out how to get the job done. -Dave -- Dave McGuire, AK4HZ New Kensington, PA

Re: Racks for older equipment
I use them for the bench equipment. I use the 6 shelf, rolling, 2
foot deep by 4 foot wide variety.? You do need to make some
modifications, though.? There seem to be two varieties, one with
the shelf lip up, one with it down.? The one with it down is more
convenient to use, the one with it up needs feet on the equipment
high enough to clear the lip.
You'll find that the wires are far enough apart to make equipment
with feet very difficult to use.? Get a 4 by 8 foot sheet of
masonite, 1/8 inch, no holes needed (it's cheap).? Measure the
inside dimension of the shelf and have the local big box store cut
the masonite to the appropriate size.? Keep the excess, it's
useful for some things.
On the back of the rack fasten at least one outlet strip.? At the
top shelf (or where convenient) put an inexpensive under shelf
fluorescent lamp strip (or LED strip).
The shelf can be moved out for access to the back of the
equipment, the light is useful, the feet don't fall into the wire
gaps.
A flat table for the workbench (not too deep) makes a decent
workbench top.? Adjustable height is good.? White particle board
cut in two makes a decent 2 foot wide workbench when doubled.

The
other thing that works well is the wire rack rolling carts.
They will hold a lot of weight and an outlet strip fits well
behind the handle. I keep the gear on a set of wire rack
shelves, roll the cart over, pull off what I need for a given
exercise, roll the cart back to the bench, and off I go.

Heh,? thanks. That's (mildly) encouraging. One issue, I had to replace the earom, so it has zero cal data, but I'm guessing that's really not a problem. If it needs cal, it needs full cal.

Hi Man, Sorry for my bluntness: tearing down a 4195A is a total madness. We use the unit all the time in the lab, worst case you can sell it. It goes down to 10HZ, which is really useful.

I picked up a 4195A top half for peanuts from a local reseller, supposedly dead, Replace a few caps, alive. He also has the bottom sections as well as the interconnect cables. Thought I'd put together a working unit, but reading the cal procedure, needs special sw, specific HP equipment, etc. (I really hate that era where you needed some lame program to do a cal). So, is there a way to cal the beast without the original cal setup? From what I can tell, there is some magic sauce that updates the unit's earom with the cal data, can't find any refs to that. I'm thinking I should just scrap it, use the parts. Or, if someone wants it (good, bright display) locally (Southern NH), I could be persuaded.

Forgot to mention that the HP P/N is 2100-1736.

Subject: [HP-Agilent-Keysight-equipment] HP 334A Balance Pots
The balance pots in my 334A have gotten pretty erratic. Am I correct to
assume these are carbon-track types and not wire-wound? I presume that this
application would demand carbon-track but in my search for a replacement,
I've seen references to wire-wound so it made me curious.
If these are carbon-track, then I'm hesitant to attempt to clean them so
wanted to confirm.
Also, if anyone knows where some good replacements are, I'd be interested.
These are 3000 ohm/100 ohm dual concentric pots.
Thanks,

Re: Craigslist HP 8566B Indianapolis
I have a few of these units all operational and yes they are seriously heavy. This unit is nice as it appears to have the interconnect cables. It is a really nice SA. There was a flood?of units some 7 years ago and another person and told me how nice they were. Well at less then $20/section I picked up a few hoping to?make one good one. Turns out far more than 1 were operational. I had randomly picked up the interconnect cables some years before that. Just because... Good luck and I would see if you can get a slightly better deal.

Re: Seeking advice on a precision DVM
There are plenty of 34401A displays on ebay for under $30. I assume they're clones since there are so many but have no reason to think they're bad. I'm hoping the prices on 53131A displays will also continue to fall.

Re: Craigslist HP 8566B Indianapolis
Just recently, I was working on my Marconi 2380 Spectrum Analyzer and realized there was a need for a decent anti gravity device. However my inquiries to the government about their gravity wave program were not met with any degree of sincerity. Apparently they have some sort of very large device that can measure gravity "waves".
I would think the dollar value of these HP and other old test equipment units would be much higher if someone would just come up with an anti-gravity device.

Re: HP54603B Software Gremlins
Hi Askild,
thanks a lot for the clear and detailed pointer.
With "nonvolatile trace memory" mentioned in the manual, I thought of something
more durable (EEPROM, FlashROM) than a battery back-up SRAM :-) Would have
been nice, if the programmers had added some CRC or at least a checksum to the
data compression throwing an error message if something fails. At least they had
time for the famous "Tetris game" :-P
As the price tag for the M48Z128Y replacement from Maxim is in the $30 range,
(and then you dont't know how old it is already) I'm thinking of setting up a
"discrete" solution with a $3 128kSRAM, a coincell and 2 Schottky-Diodes
(or a DS1210).
Cheers??? Andreas

Re: Hints on removing burned tantalum residue
So I looked up this HexaWave HWF1681RA - definitely a MESFET. If it turns out they're shot, you may be able to find NEC brand equivalents. I vaguely recall that I have some amplifiers that have NEC-something-something-8001 or 8002 types that have similar Idss specs. I don't recall the exact part numbers, but you may find a bunch searching NEC/CEL (California Eastern Laboratories - their US distributor way back when).
