The simulator work could greatly benefit from the IBM 1620 & 1622 manuals and system
diagrams that you have.
Connections to the console aside, the best materials for this would likely be the CE/FE
instructional manuals. Those were invaluable to me when I wrote my 1410 cycle level
simulator. They are also a huge guide to interpreting the drawings, though I did not use
the drawings to write my simulator. You might reach out to others who actually have 1620
hardware directly.
