Nick,
Thank you for taking the time to scan, archive and upload all of this information!
Since not everyone owns a PDU, do you happen to know if anyone has ever figured out how to run the software on a different device, such as a laptop running Linux?
Hopefully someone will find this information useful

Hi Nick, for the XJ40, is it just the jtp626_6 and jtp626_7.iso's that I need? (plus the manuals of course)
With the PDU, does it have any built-in Jaguar specific OS or does it need one of the disks loaded to enable it to boot up? I guess I'm asking if you think another similar GENRAD machine (for another make of car) could be used?
I'm aware of the FDS 2000, wonder if cabling is similar?
Lawrence, you are correct, those are the two ISO's that are applicable to the XJ40. The PDU does not have any means of permanent storage. The unit has a small amount of memory which is used to store portions of the software on the CD-ROM. The unit first loads the Operating System from the CD-ROM, and then the specific application selected from the Main Menu (for example, Guided Diagnostics, Toolbox, Analog Datalogger, etc.)
This means that if you've loaded the software for a '92 XJ6, and selected the Guided Diagnostics application, the unit will need to be brought back to the base station if any other application (Analog Datalogger, Toolbox, etc) needs to be used.
This is why working batteries are a must in order to use the PDU. The battery keeps the memory powered while the technician travels between the base station and the vehicle, where the VBA (Vehicle Battery Adapter) is connected to the PDU. The VBA provides correct operating voltage to the PDU via the vehicle's battery. I've purchased new 7.2V NiCad battery packs for both of my PDU's and they fit and work wonderfully, needing only slight modification to the wiring on the battery pack's connector.
The Ford FDS2000 is the Ford-branded version of the Jaguar PDU, both are manufactured by GenRad. I'm reasonably sure the only difference between the two is the battery cover plate with either the Jaguar or Ford logo. Also, because the Operating System is loaded from the CD-ROM, it's my belief that a Ford FDS2000 can load Jaguar CD's, and vice versa. Even the very minimal firmware when the PDU boots has no Jaguar-specific logo, or branding at all, leading me to believe that software can be interchanged.
With that being said, the cabling for the Multimeter portion of the PDU (Black and Red test probes, Ammeter Clamp, etc.) is identical. The difference is when you're getting into Toolbox and Diagnostics functions. Earlier Jaguars use the PM4 connector to transmit serial data to/from the car. Fords use a different connector, probably an early OBDI connector.
The main challenge is finding a working Base Station module, as the proprietary Sony-bus CD-ROM drives are very, very flaky now that they're approaching 20+ years old. I did find an external Dual-Bay Sony-bus drive that I was able to steal a working CD-ROM drive out of for use in my own Base Station. The unit was a Sony CDU-6250. The drives look like they have a standard IDE/ATAPI interface, as the cables are the same pin-count, but they are very different electrically. You have to remember, these PDUs were made in the days of computers with ISA Sound Cards that controlled the CD-ROM interface, and Sony, Matsushita and Panasonic drives all had different interfaces. This was before ATAPI/IDE standardization of CD-ROM drives.
Nick, you've pretty much confirmed my suspicions re: the two units. Thanks!
btw, I've forwarded your description to an old friend who restores vintage synths, a lot of these use somewhat proprietary drives, some even use proprietary floppy drives. Hopefully he'll have a suggestion or two regarding the CD units.
And Don, I'm afraid I don't think the hardware functions of the PDU could easily be replicated by software, or off the shelf personal computer hardware... Even though it's old technology by today's standards, it's still quite advanced stuff...
For people who are having problems with the Sony CD drive, I have a solution for it!
I am building new circuit boards which are a direct replacement for the original board inside the Jaguar PDU (Ford FDS 2000) if the CDrom player fails. No need for any soldering just 2 screws and its is plug and play. The original players are non ATAPI drives as mentioned earlier and fitting a new modern player will not make the system working again. This circuit board makes it possible to fit any ATAPI drive, also giving much higher loading speeds as the original Sony only had 1 speed. So this board can be used as an upgrade as well.
Does anybody has got the final discs
JTP 627/7 (XJ40 and XJS) and
JTP 627/10 (XJ, XK8 and S-Type)
JTP 628/3 (PDU to PC for printing?)
I tried to burn the JTP 626/7 from the Dropbox on a CD but the PDU doesn't recognize the CD. (Yes I did'nt just burn a .iso file on the CD). The file is 88.11 MB and in my opinion that is to small for a PDU software CD. If I make a .iso file from a working disc (PDU 1031) it will be 458MB. Any thoughts or experience with burning the files from the Dropbox into a CD?

I have also tried to copy a disc to see if it would work, so we would have a backup disc if one became damaged, but so far have been unsuccessful.
Can you tell me, what is the Dropbox you are referring too?
I see a serial port on the back of the PDU drive case, is it possible to connect that port to a PC and do any downloading that way?
Let me check around to see if anyone has been successful in copying the discs and I'll let you know. I wanted to do this anyway for ourselves, so I would like to help you if I can.
I can confirm that CD-R copies of the original Jaguar discs work for me. My PDU came with a copy of 626/7burnt onto an old plain Jane "Systemax" CD-R, and I've been using it with zero problems, both with the factory original Sony CD-ROM drive, and the replacement Sony drive that's slightly newer than the original.
I even made a copy of the copy on a printable CD so I could get the proper Jaguar label. No problems whatsoever.
I used PowerISO for copying and burning, set to burn on Verbatim CD-R media at the slowest speed possible. Perhaps it's a CD-ROM drive that is averse to burnt media. Many older drives (think of original CD player head units/changers in early 90's cars...) simply refuse to read them.
The serial port on the back of the unit is meant to be connected to the "Jaguar Multimedia PC" which was used by the dealers for Multimedia Training Courses on CD-ROM. JTIS could also be installed on the system as well. PDU-PC Software was installed as well and allowed the printing of traces and OBD Reports from the PDU to back up warranty work submissions or to have a hard copy.
PDU-PC Version 3:
Here you can see where you set the COM port that the PDU is connected to:
If anyone has the PDU-PC Software or ANY PDU CD-ROMs that we can add to the library, please do upload it! It's greatly appreciated

i recently bought a fds 2000 for 50 euros and now i am trying to use it as a pdu
the fds2000 is fully functional as a ford diagnostic but somehow i donīt get the pdu software cds to load
seems like the cd rom cannot read them
i have 4 pdu cds which are
1041a
1055
jtp 626-7
jtp 627-10
what is the right order to load them, do i have to load 1055 first and then put in 626-7 to have access to xjs files for example?
i donīt have the right cable for the pm4 connector or the specific diagnostic connector of a 93 xjs that is in the trunk, does somebody know a source for those cables?
or is it possible to solder one by myself?
my fds has a later dated toshiba cd rom, which is already atapi , the fds is from 1997...is it interchangeable with another cdrom from that period that is also atapi?
any help appreciated...
Congratulations! I have a Jaguar PDU and Ford FDS both working with the Jaguar software so that is no problem.
1 Do you have original CD's? If no try an original CD.
2 There is no specific order to load the CD's, just put 626-7 in and it will deal with the XJS
3 First get your base station to work then I think we will be able to get the wiring scheme for the cable, an original cable for the XJS would be hard to find (I think).
The later FDS model number is 3130-0019-02 (with the updated circuitboard using an Thoshiba ATAPI CD drive). If so, you would be able to put an other ATAPI cd drive in, but you can try to open your drive and clean the lens to get it working again (it wouldn't be the first one).
I would love to find the large plastic coated display sign like we had at the Jaguar dealer that had all the software designated for all the applications.
It had the Models and what disc for what.
I think the PDU and ALL the accessories got tossed in the scrap.
