Important note Firmware images available here may have two formats – Odd+Even combo, read as is from ROM chip, and full binary file.
While most of today systems are using little endian for storing data, old Motorola 68000 CPU used in lot of Keithley instruments using big endian, so before you flash your ROMs, make sure endian is correct.
Easy way to check – open binary with HEX-viewer and find some text strings, as example electrometer’s 6517 will have next strings on offset 0×400 in big endian:

00000400   65 4B 74 69 6C 68 79 65  49 20 73 6E 72 74 6D 75  6E 65 73 74 20 2C 6E 49  2E 63 6F 43 79 70 69 72   eKtilhyeI snrtmunest ,nI.coCypir

While little endian representation is:

Also little and dirty tool could be handy to generate ODD/EVEN ROM files from single unified binary. It’s written in C, and really dirty and quick, but seem to do it’s job.

Tool to split single ROM binary into ODD+EVEN halves Source code
Also conversion tool for Motorola SREC format (*.x) and binary can be downloaded here, thanks to www.s-record.com

Now, here is prompt catalog of Keithley data for some of models, as listed below.
It’s not all data available, only what is categorized and checked (manually :).

Thanks to Lightages EEVBlog member

How do I put the Model 197, 175, 485 into Cal Enable mode?
Depending on the firmware revision, there are three methods to put these instruments in the CAL ENABLE mode.

  • Firmware A revision : Has an internal cal enable jumper. There is no indication on the display when cal mode has been enabled. CAL mode is enabled with the jumper to the left when looking at the instrument from the font.
  • Firmware B revision: NO internal cal enable switch, performed digitally through sequence during power up. (see procedure below)
  • Firmware C revision : Has external cal enable switch on rear.
    Procedure to CAL ENABLE for Revision B firmware:
    In Service Manual, delete paragraph 5.6.3 Calibration Jumper on page 5-4 and Figure 5-2 on page 5-5 and replace with the following:

5.6.3 Calibration Storage Enable

The Model must be in the calibration storage enable mode in order to realize storage of calibrations constants into the NVRAM. If the instrument is not placed in this mode, subsequent calibration will be lost when the instrument is turned off. Perform the following steps to place the unit in storage enable mode:

  • Turn unit off
  • While holding in the STO/CLR button, turn the instrument on using the ON/OFF switch.
  • When the “CAL” message is displayed, release the STO/CLR button. This instrument will return to normal display mode, and the storing of calibration constants is now enabled.
  • Allow 1 hour warm up before proceeding with instrument calibration.
  • Press in the REL and dB pushbuttons simultaneously until the message “CAL” is displayed again. Release the buttons. The unit is now ready to be calibrated as indicated by the “C” annunciator on the display.

Note: Step 2 and 3 put the instrument in the CAL ENABLE mode, while step 5 puts the instrument in the CAL mode.

The included files are annotated versions of the main (non-power supply) section of the Keithley 225 Current Source. Both files include layers which will allow you, in a suitable program, to hide or show the annotations as appropriate. Also included in the schematic are some notes on suitable replacement parts for the original transistors, most of which are no longer available.
