I didn't recognize the model name, but looking at the PDF Steve Simpkin posted, I recognized it instantly
I recall a friend having one in about 1981, after a family member upgraded to one of the brand new 12c's... I never got to lay a finger upon it. He did use it playing D&D, mostly for party shares of XP and loot.
