Finally I got my TDS5054. It's mechanically quite badly abused (dropped), but I managed to fix bottom covers. Electrically it's seems to be working nicely (SPC gives OK). I added connector to serial port, but there is only couple character when scope is starting application and there is no c:\vxboot folder. I tried to find some debugging information to this series, but there is very little to found.


I also looked acq board/front end modules (didn't remove covers), there is capasitors to gnd on every modules back side (C325+C332) and instantly I remembered how to modify TDS754->TDS784 500MHz->1GHz bandwidth. Is this similar difference between TDS50**/TDS51** 500/1000MHz...

there is no c:\vxboot folder.

It may be hidden... Check your explorer view options.

Hi, I'm little late, but does anyone have this option stuff saved?

Hey, no idea why the link doesn't work. Happy to send a copy to you if you want to PM me.

I'm not finding either sites up:
https://xdevs.com/guide/tek_key/
https://dev.xdevs.com/projects/rnd/repository/revisions/344cfa743297/raw/Tektronix/TDS7000/

I'd be very thankful for a copy.

Background if you are interested:

I received a few days back a TDS8000B that was stated on eBay as having Power Supply issues where they noted:
"Originally it was working but came back to us with a bad power supply. About once out of 20 times it will power on and light up. Sometimes it turns off by itself while booting. Most times it won't turn on at all then will make faint clicking ticking noise in the right rear of the unit. Screen has some scratching."

I powered on the unit and first time not thinking about having a keyboard plugged in to login and perform more testing as my brain was set to modern day touch screens with keyboards that appear on-screen as factory default.   Powered on no issues, though is slow Windows 2000 Pro for sure.

After plugging in a USB keyboard with a USB to PS2 keyboard adapter, I pressed the power button on the front panel and was having no success with being able to use the keyboard to log in.  I am guessing something to do with USB keyboard drivers is the reason.

Now, after holding the front panel power button for over 7 seconds, the unit powered off.   When I tried to power back on, I heard a mechanical clock ticking sound with nothing happening.  When I switched the power switch on the back of the unit the ticking sound slowly went away and all subsequent attempts to power on have failed with nothing happening.

Before I open the case up... any ideas to consider as I am making a giant leap into working on this system as I am still not yet graduated from a TDS-520 repair/restore... though am moving forward on that and learning a lot. 

Just reading this page topic summary has bridged the programming firmware and electronics components like NVRAM and microcontroller gaps I've had.

Sounds like caps in the power supply or possibly on the motherboard.

Also if you can't get into the bios setup you need to first check your cmos battery on the NLB motherboard and replace it if it is dead. Likewise for the power PC board. If your scope is anything like the experience I had with a TDS7054 then you probably still won't be able to get into the bios setup so you need to boot up in dos on a floppy and run a program like killCMOS to reset your CMOS memory and then you will, beable to get into the bios setup.

http://www.majorgeeks.com/files/details/killcmos.html

You can create a bootup dos disk from another computer with a floppy using the setup from http://www.allbootdisks.com/download/dos.html

cheers

Hi, all explorer setting should be in right position to show hidden files/folder. This is TDS5054, should there be \vxboot folder?

Hi everybody,

I worked on my problems with the TDS7054 and I hope that I have found a final solution.

As described I get this DIO.exe "illigal operation" failure, so I decided to install fresh Win2K, cause the Win98 Version was installed in 2001. After installation and get all necessary drivers I started the Tek Scope Software 2.5.5. Everything worked, the scope buttons where on screen, the frontpanel worked correct, but there was no waveforms shown on the screen  |O.

In the documents of my scope I found an Win2k updateoffer direct from Tektronix. There was written, to update my TDS7054 the mainboard must be changed  :--

So I conclude:
My Scope has the old BL440ZX PC Mainboard with an Celeron 533 Prozessor on it and with this board it isn't possible to run Win2k and WinXP. If anyone knows a solution to run a newer OS on my scope please describe here!

So deeply disappointed I installed WinME (had no 98 install CD and ME supports USB Sticks) on a newer Harddrive.
After insalling all drivers and the TekScope App at least my Scope work fine whitout the DIO.exe failure.  :phew:

@ Serge: Have you managed get your Scope working?

schersch

Hi schersch and all, I have some new info:
1) It DOES work!
   I mean, I've managed to install win2000 on a BL440ZX. Steps are what someone here already mentioned:
   a) Fresh win2000 install
   b) Install custom drivers (for front end, fonts, etc.)
   c) Replace the standard "Chips and Tech 69000" driver with the one mentioned here
   d) Install 2.5.5 firmware: this is where it got difficult because no matter what I did, it always mentioned that the file was "corrupt" while decompressing the install exe.
      What I did is take the different setup files directly from the temp directory of my previous win98 installation.
      Unfortunately I can't attach them here because it weights around 60MB but if anyone wants to retrieve them you can by starting an installation of the exe on your "regular" PC and when you get the message that "This is not a TDS...etc etc" you simply go to the TEMP directory mentioned in the first step and grab the folders and setup files from it ;)
   e) VoilĂ !   :-+
2) I've installed 512MB and 256MB DIMMS on the mainboard slots but they're topped at 128MB only each. I think this is a BIOS thing: I'll try to find a newer one (are there?) my current version is: 4B4LZ0XA.86A.0007.P04
3) With both slots of RAM occupied with 128MB and a 4200RPM Hitach Travelstar I get a boot time of 2mins 10 secs aprox: not great but not unbearable either.
4) I can't seem to see a difference by installing more than 128MB on the PPC board... does anyone do?

Regarding bullet 2, I found this later BIOS version:
    * 4B4LZ0XA.86A.0012.P05.9911041309
    * CPU BIOS Updates: MU665(03)
    * Intel UNDI, PXE-2.0 (build 074)

    P05-0012:
    * Note: This bios is not compatible with the boot block of P04-0007 or earlier BIOSes.
    * Fixed issue where system would delay before booting Windows NT when using a SCSI drive and not having IDE-HDD before the SCSI Adapter in the boot order.
    * Fixed PMM allocate to consider unallocated memory holes for allocation of new memory.
    * Fixed serial port device node static configuration changes.
    * Added DMI memory structures.
    * Removed Serial Port B setup questions and PnP device node.
    * Fixed Fault Tolerant update of Vital Product Data (VPD)
    * Errata: Recovery via LS-120 not currently supported.

Although the 3rd bullet could be the answer to removing the limit of 128MB I'm not sure if it's compatible (specially because of the "Note" part) does anyone know?

You must use double-sided 256MB DIMMs to get to 512MB

Mmmm, I'm not sure I follow you, I put one DIMM of 512MB and got only 128MB recognised: what BIOS/MOBO you have?

512MB DIMMs will not work properly at all in the BL440ZX board.
256MB DIMMs will work if they are double sided. IOW, 16 memory chips (8 on each side of the PCB) need to be on a 256MB module for all the memory to be detected. This is a chipset limitation.

No problem. I just noticed that you were discussing BIOS versions for the MB. I would NOT recommend flashing unless the BIOS was released by Tek!!! You might end up with a door-stop.

Funny I should see this thread, purchased a TDS7254 for a cheap price, just arrived and has no HD.

Any ideas where I might be able to get an image for Win2Kpro embedded for it?

Otherwise this thing is looking OK, at least physically and from the intel side of the equation it seems to function OK.

Wolfy007, Install Windows XP! If you have a 440zx motherboard, there are drivers in this thread. To restore NVRAM, use a natural PC232 that connects to the Console connector. The only thing that did not work out for me was to launch the touch panel. The working version of the Telescope program is 2.5.5. The one on the Tektroniks website version 2.5.3 did not work for me.

Well so far so good, nearly all up and running (Intel 810 chipset). Just need CPU update and get the ethernet working, and waiting on TCA adapters for final testing.

Well tore it down to do a closer inspection, clean it a bit (fairly clean already), check caps etc, then I saw the two chips pictured on the acquisition board.

Last date code appears to be mid2002 for this scope, fans run smoothly, caps are looking in good shape and power on diagnostics pass. Voltages look OK, but on extended diagnostic I get a couple errors as shown below.

Appear to be part of triggering on the acquisition board. Dont suppose anyone has a dodgy acquisition board with these two chips still in good shape that they wont mind donating to this project? Or if you know a reliable supplier with stock. Chip required is the Tektronix 156827800 (x2).
