by the way, when you say the scope suddenly died, what exactly do you mean? Are you even sure that it is the hard drive malfunction? there are many other possibilites if it is confirmed to be the hard drive, then as I mentioned before, you do not need any ghost explorer or win xp or anything . all you need is download a bootable win98 floppy from internet with CD ROM support (many available) and make a bootable floppy you can get a nice little USB floppy drive for $10-$15 from amazon or something if you need then you burn the 3.5 recovery iso image? on a CD ROM (even windows built in cd burner works) get the image from Tony G depository here then you need a 40 pin IDE cd drive to be connected to the motherboard directly (again very cheap to find or pull from old PC) get a compact flash (CF) card and CF card IDE adapter (40 pin) and insert it right on top of the IDE connector on the motherboard you can get the 5V supply for that from the nearby USB header on the motherboard boot the scope to floppy and navigate to the CD rom and run the ghost.exe and watch it for a while and you are done but first you need to make sure it is really the hard drive that has died

+1 for Amirb's suggestion of a CF IDE adaptor. I've done this on a number of instruments.

Re: First Gen HP 54810A with dead HD, Got ISO 3.5, Any way to write it to a drive?
Hi Rik,
That is because the format that they use for storing the likely
compressed data is their own proprietary format.
dd can backup/copy a full disk, or a partition, or a file, it
doesn't care. It can deal with errors in a variety of ways, and
it can compress the results of its backup, and uncompress the
backup while doing the restore.
Very versatile, and free with linux.
Ok, you don't like linux, you say?
That's fine, download an ISO of any linux live distribution,
and boot into it from the CD/DVD, or thumbdrive, on your
machine, and use dd to do your dirty work. Still free.

dd simply copies the disk exactly as the data appears on the drive. It is used in
forensics to clone drives from crime scenes as it makes an exact copy down to
the partition tables, and bad block tables.
What is your definition of a ghost image?
I recall it to be an exact clone of the drive.

Re: First Gen HP 54810A with dead HD, Got ISO 3.5, Any way to write it to a drive?
all you need is a win98 bootable floppy + a CD drive (either an external parallel port CD drive which is hard to find or an internal IDE one which is cheap)
you boot to DOS and run the ghost from the CD drive.?
I have done exactly this way to at least three 548xxA scopes...and get rid of the scope's hard drive. put a new compact flash (2GB or 4GB will be more than enough)
with IDE adapter ($2-$4 from china)?
you can go the SSD way but for such and old scope with win98, I wouldn't bother...

Re: Fixing a sick 4332A LCR meter
Hello Sean,
I'm answering your questions out of sequence, but I'm sure you'll be able to make some sense out of this !
* I wrote about the emitter of A2Q2 but I meant A1Q2, I'm sorry for the typo.
* The 4332 has linear scales, so it's normal for the ohmmeter function to "peg" the needle if the input is open-circuit. Of course, "infinite" is way above full-scale!
* Since the ohm-meter is *somewhat* functional but reads a resistance value which is much too low, I believe there's something wrong with the oscillator. My 4332A puts out a 77mV signal at the INPUT terminal, a point where you're seeing only 12mV. Of course your mileage may vary, but I'd suggest we first look at the oscillator. It's described in the manual on page 4-3, paragraphs 4-11(a) and 4-11(b). Please probe the signal at A1 TP1 or the emitter of A1Q2, which is the oscillator output. Paragraph 4-11(b) says there should be 70mV across A1R37. Is the amplitude OK ?
If the amplitude is too low but the signal still looks like a clean sinewave, the next step will be to look at the rectifier A1IC2 and the voltage comparator A1IC3 which control the oscillator amplitude via A1Q1 (a FET which is operated as a variable resistance to control oscillator amplitude). For example, a fault around A1IC3 would cause an error in oscillator amplitude, similar to what you're seeing. But I'm thinking aloud here ...
So, please let me know what you see. And, just as a matter of personal curiosity, in which timezone are you ?
Sincerely,
Joel Setton

Re: 8510C questions and cabling
Hi Reg,
I am not familiar with the test sets you are using, so I was only
telling about the sweeper.
Here is what I have on my system:
Display: 8510 Interconnect HPIB cable to Test set, and Sweeper.
.........IF Display Interconnect to 85102B IF Display Interconnect(J2)
85102B: IF Display Interconnect(J2) to Display IF Display Interconnect
.........Test Set Interconnect(J1) to 8514B Test Set Interconnect(J11)
.........10MHz in from sweeper.
8514B: 8512 Sys BUS(J12) to Display and Sweeper (HPIB)
.........85102B Test set Interconnect(J11) to 85102B
.........8514B Test set Interconnect (J10) unused.
8640B: HPIB to Display and Test Set
.........Sweep In from 85102B
.........Stop Sweep from 85102B
---------10MHz to 8514B.
I have left off little things like the Extension jumpers on the
test set, and the int/ext clock jumper on the sweeper... you should
be able to figure them out.

Chuck,
That is page 1-3 of the document I referenced in my post. Neither of my 851x A/B test sets has the source interface. However, I just noticed a note on that page that the source interface is only used with the 8516A. The figure is much too busy.
You don't mention the J10/J11 test set interconnect in your list. There is no display on the 83631B, so without connecting it to the 85101A & 85102A there is no way to get anything displayed.

Re: First Gen HP 54810A with dead HD, Got ISO 3.5, Any way to write it to a drive?
I had the same problem with another machine. The pin
corresponding to the missing hole doesn't have any connection so
solution is easy, you can:
1. Cut the pin,not so easy and difficult to undo.
2. Use a small drill bit and make a hole in the connector. When
you finish you can use a a plastic plug to cover the hole and
restore the safety feature. Before making those special connectors
with the hole missing, many manufacturers used standard connectors
with the plastic plug.

Orin, I found it!? R14 is burned.? Diagram says 100 Ohms, and it measures around 4k and is all blackened.

Well, looks like you?are getting closer.
CR7 and CR8 just clamp the amplifier output at TP4 to > -17V or so.? They are could be OK as you were seeing > -17V.
Q8 may well be shorted - what's the voltage at TP4 now?

Should I replace U2 or maybe Q7 and Q8?? With what?? Those have proprietary HP numbers I am sure.
But maybe a bit more troubleshooting to make sure.? No sense in replacing all three parts when perhaps they are all good.? It's not simple to remove parts without damage to the board, I think it's double sided and takes a lot of heat.

Re: First Gen HP 54810A with dead HD, Got ISO 3.5, Any way to write it to a drive?
Getting there.. I think.. I found an old ghost explorer version 6.03 that came to live on my windows 7 laptop I use for Volvo VIDA and the Rosstech tools for my cars.
I was able to recover all the files from the .gho file to a folder and to a "new: hard drive. A total of 647Mb and 5023 files in 222 folders.? The files I was able to recover from my old drive was 280MB in 74 folders and 2363 files.
Looks like the 3.5 is Windows 98.? ?Hopefully I have enough memory.
I will try to create a boot floppy tomorrow and see if I can make the hard drive bookable...? This is giving me bad flashbacks... I went from Sinclair ZX 81 to Sinclair Spectrum to Wax 11/780 to Mac to Windows NT, XP, 7 and 10.? I never dealt with windows 95,98 and Vista.
