Who remembers these? RPG coding sheets

When I posted pictures of the IBM print charts I had found, Kevin Adler sent me pictures of some of the RPG history he has, RPG coding sheets.

Looking closely at them I think they may have been sheets used in the days of punch cards.

When I asked Kevin how he came to possess them he replied: "I got them from a former team leader before he retired."

  1. Of course I remember, I used them to transcribe the RPG programs through a dual IBM 3742 with 8-inch floppy disk in basic data format (128 Bytes per record) and then use the TRANSFER procedure to download it to a 64 MB fixed disk Which weighed 40 KGS. Installed in an IBM System 32 and / or System 34 year 1977

  6. The RPG-rule had all the coding sheets plus the EBCDIC hex symbols. It even let you measure card volume up to approximately 2,000 cards. In addition, it had line spacing for 6 LPI and print positions at 10 CPI up to a max of 150 characters. I even had my name engraved on it. Far outlasted the S/3 Model 10 I was working on at the time.
