Title: RE: AS/400

Well, heck, I sure don't remember the model numbers of the card readers, but I had an RPG 1.5 class that compiled on an IBM 1130.  Towards the end of the semester, we were effectively limited to one compile every 4 hours, what with the backlog on the card reader.  Heard a lot of cursing when there was a simple syntax error and the compile failed. 

For advanced RPG II, we had to go to the local hospital (where the RPG instructor worked) that had a screamin' S/3 WITH INTERACTIVE TERMINALS!  Wow.  I remember thinking how hot *that* was!

I am *not* as old as dirt!

        You and I are probably the only people that actually worked that
equipment.
        I remember placing rpg code, inside a compiler deck of cards.
