Fluke 9110FT SPECTRUM-TX diskettes imaged
by Martin Olsson 10 May '23

10 May '23

Hi all! I bought a Fluke 9110FT setup and with that setup came the SPECTRUM-TX diskettes which I now have imaged and uploaded to the "/TTL/Test_Equipment/Fluke/9100 Series" folder on John's FTP site. Inside the ZIP archive is a ReadMe with more details about the images etc. I haven't tested the images myself but I think they should probably work as the original diskettes was error free. Enjoy! /Martin! _______________________________________________ Techtoolslist mailing list Techtoolslist(a)flippers.com https://pairlist7.pair.net/mailman/listinfo/techtoolslist FTP site is: ftp://ttl.arcadetech.org/TTL/Test_Equipment Archive site: http://seven.pairlist.net/pipermail/techtoolslist/

ftp site is down...
by John Robertson 23 Dec '22

Does anyone know Tim Matthews (in the UK) and can ask him if he is aware his web site arcadetech.org is down? He is hosting the TTL library (I have a complete archive of course) and I noticed it was down when I tried to upload some files yesterday. I sent him an email but did not hear back. The domain is listed as active until 2020 so it must be a server thing... Thanks!

Fluke 9100 system EEPROM disambiguation
by Andrew Welburn 28 Apr '22

28 Apr '22

hi all. There's a 32-byte soldered-in I2C serial EEPROM (type X2444) that contains crucial hardware setup information use in the Fluke 9100 series systems. The values in this eeprom hold information pertaining to some calibrations as well as all basic I/O hardware. This information can all be set/changed with the use of floppy service disks in a working system. If you happen to set the wrong floppy drive type in this menu, you can lock yourself out of being able to adjust anything, as well has having a non-working floppy drive. You can re-program the chip in-circuit (in theory, but i didn't try it) or you can de-solder it, and dump the contents/reprogram it. The 32 bytes might be a little cryptic, but with trial an error i have found out the following address map. It is not exhaustive, there are likely more things stored in here relating to IO mod or pod or probe calibrations accessed in the setup/calibration menus from a regular boot cycle, but for now, this is what i have discovered: offset Purpose Notes ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 00 to 03 Serial # Little Endian 04 System/disk type Note1 05 to 08 Probe offset calibration values 0A Disk err reporting 00=OFF 0A=ON 0C,0D unknown do not change 0F RAM size Note2 11 Network Node 00 to F4 is valid 15 Floppy type Note3 18 to 19 IEEE option YES=04D7 NO=14D7 1A to 1C site # Little Endian 1E to 1F checksum Note4 Note1 = 42=9100/Miniscribe 76=9100/scsi512 66=9100+scsi256 00=9105/9050 Note2 = 18=1.5mb 20=2mb 30=3mb 40=4mb 80=8mb F0=15mb Note3 = 00=Gotek 01=Canon 03=Sony 04=Mitsumi 05=Teac 06=CanonHD Note4 = BSD Checksum, but barrel-rotated right 10 bits then inverted see: http://www.andysarcade.net/personal/tech/fluke9100/andysum.zip Big props to TheMogMinor/MooglyGuy for figuring out the checksum, as well as writing the utility and providing source code! Now you can create a binary yourself, generate/apply a valid checksum and write this to the ROM and get yourself back in business. enjoy. -- Andrew Welburn andys-arcade _______________________________________________ Techtoolslist mailing list Techtoolslist(a)flippers.com https://pairlist7.pair.net/mailman/listinfo/techtoolslist FTP site is: ftp://ttl.arcadetech.org/TTL/Test_Equipment Archive site: http://seven.pairlist.net/pipermail/techtoolslist/

Fluke 9010a ROM Signatures using CalcSignature.exe
by Bob Economaki 15 Apr '22

15 Apr '22

Hi Team: I am trying to sort through my 9010a System ROM versions using the signature tool located @: http://tech.quarterarcade.com/tech/Fluke/9010A/CalculateSignature.aspx I am looking for the Fluke Signatures for Versions 2B, 2C and 3A ROMS. Specifically Version 3A If anyone has burned and/or tested version 2B, 2C and 3A ROMs in their 9010a and you have the raw binary files for the ROMs, I would appreciate what the above CalcSignature tool generates for your known-good ROMs. I am in need to burn some ROMs and a sanity check would be helpful. Nice Fluke Sig tool.
