thanks John for help...... found ftp://ftp.flippers.com/TTL/Test%20Equipment/Fluke/9100A/ has at least 5 ram files... to bad you can't find away to read xicor form external program.... I had problem w / teledisk until I used version 2.23 worked fine ....service v1.2 older service with hd format and no serial req'ed Al ----- Original Message ----- From: "John Robertson" <jrr@flippers.com> To: "Technical Tools Mail List" <techtoolslist@flippers.com> Sent: Tuesday, April 26, 2005 12:37 AM Subject: Re: [Techtoolslist] Fluke 9100a X2444 question
Well, checking my archives I see there is some documentation by me... -------------(start old message 2002)...........................
I have had the recent opportunity to dig inside a couple of 9100's lately (I bought a few NOS ones) and I kept one to go along with my old 9100. Now the problem with these suckers is the software is keyed to a serial number embedded in the EEPROM that is tucked away on the main PCB. It just so happens that this part (an Xicor X2444 - 32 bytes) is readable by my Xeltek Superpro programmer so I unsoldered the one in my old base and read it, and then tried it again in the original base. Still works. So then I decided to unsolder one from my keeper NOS 9100 and read it tonight.
So what I have is two 32 byte data streams, the first one (old base) is serial number 4900002 (unknown Site Code) is: A2 C4 4A 00 42 03 FF FB 01 00 0A 00 03 50 08 40 00 00 00 00 00 03 00 00 FE 02 00 00 00 00 BF BE
And serial number (NOS) 4775000 "Site Code 1" is: 58 DC 48 00 42 00 FC 00 FC 00 00 00 03 50 08 20 00 00 00 00 00 00 00 00 FE 02 01 00 00 00 23 0F
The first 9100 has the following options: 4 megs of RAM installed Sony floppy Programmers option w/video card Version 4.X software?
The NOS 9100 has 2 megs of RAM ? Floppy Version 4.1 software
I'll dig out more from these using the utility disc this weekend. I think the "40" on the first row last byte is the RAM size, this makes sense as the second 9100's is only "20" (2 megs), I suspect the first three bytes are the serial number...maybe...
I accidentally copied the Utilities disc to the old base and it has taken over the drive from the original operating system. If anyone has 9100 discs they can be archived and stored via TELEDISK (old DOS or W95/DOS) program...I'd like a copy for trying to figure this protection out for archiving. -----------------(end of 2002 message)-------------------------------- John :-#)#

Those (undocumented) RAM dumps were from various 9100's X2444 serial RAM devices that I took in an effort to try and figure out how the serial number was encoded. I lost interest due to other more pressing matters..and in fact haven't touched my 9100's in over two years now (I think). Sigh.

I think these ram files are the key to making unit work......... any help would be appreciated.........
