Today's video is about a Pac man clone written in GWBasic. This one was a type-in from a IBM PCjr book as far as I know. I couldn't find which book sadly.
If you want to check it out the file is available in Rob Hageman's hoard of GWBasic. You'll need to load the file in the interpreter to get it to run or read the source as it is in the tokenised format.
I was going to put a link here but google didn't like it, you can modify the following to put into an address bar...
