Peter Pan Playthings Master Challenge (1980, LED, 9 Volt, Model# ??)
Licensed from Coleco (Coleco's Quiz Wiz system), this was released in the U.K. by Peter Pan Playthings. There were 30 different cartridges for Coleco's version, I'm not sure how many were released for this system in the U.K. I know many of the cartridges are different, there are several for this system that deal history, television or other things that are specific to the United Kingdom.
Do I have this? Yes, boxed.
