The Apple ][ plus was in production from 1978-1982, which means it's about as old as I am. It has a built-in capacity to understand the Applesoft BASIC programming language (which I happen to have taught myself, geek that I am, while in the 5th grade). This arcane knowledge came in handy when trying to get it to do something useful, like play Frogger.It runs completely off of 5 1/4 in. floppy disks. (It has no hard drive.) I could only find one disk: the one that was still in the drive. It had three games on it, but the menu program to select the games had some corrupt data and wouldn't function.
Thankfully, I remembered enough of the old BASIC to type in "BRUN FROGGER" and in no time I was as happy as a frog in traffic!
