RTC Master 128 Docs - Our friendly neighborhood sleuth,  Colt45, did some digging and uncovered some documentation that was hidden in a .PRG file.  Turns out it was just a .SEQ file that had been renamed. 

If you're curious about RTC Master 128, you can grab it HERE.

Thanks Colt45 for all your help!

P.S. - It is suspected that this program was used with the online service GEnie, can anyone confirm?
