RCA CTC101CL12 need service manual

[va-vid]

I have an early eighties RCA Lyceum JER985SV TV intended for classroom use that I intend to use for a special project. It has line level video composite inputs on the back. I need the service manual, but am concerned that the SAMS CTC101C photofact that I just ordered will be too wrong to do me a lot of good (it is for a whole series of GER series TVs). Does anyone know the RCA chassis numbering scheme? Does anyone have the exact manual for this TV?

I have the original sales brochure for this TV in very good condition that I am willing to share with interested parties.
