2611 SMU (NON A, NON B) Programming Reference

I cannot find programming reference for my Keithley 2611 SMU. anywhere.  It seems that the language is a subset of the 2611B. but it especially lacks timer and trigger commands which exist in A or B version.
Anyone owns the doc?

Regards,

Kevin

Hello,
The PDF is too large for attaching, so here is link to Box:

Reference Manual for the original 2600 models

thank you so much. I have a doc with the same title, but mine has only 114 pages?!
