Wanted a copy of IBM manual part # SY31-9002 this is the general IBM 21ED (Hard) Disk Drive Manual.
This request manually is some time found with System/36 models 5362 and 5360 documentation.
..
A copy of this manual can sometimes be found with the (FE) manuals from some IBM system/36 computer systems.
If it is included in any System/36 users that have documentation it is normally in Volume A3 section 95 has the 21 ED Disk Drive SY31-9002 manual and sometimes Volume C1 ITC, History, And Field Logic Diagrams has a chapter for this unit included.
..
Thank you.
