Well as for "Mad Bomber" that one had various dirivatives through DOS from V3 through till Windows 8. Sadly I guess the original program from the dim and distant past is forgotten. I saw this program back in the late 78. Back then I had just got my hands on the schools IBM / early PC. The new ram chips took us into a new world and the recently aquired Cassette backup system made life happier for all.
The game was a project being done in the schools info net, at that time it was a pile of papers being sent out by a central office in the county. Not many schools had a computer and those that did, very few were able to get near them.
Having sat and typed in the code, it had to be altered I recall because of our computer setup and the lack of a full on compatable DOS. Most of the code just displayed a 10 x 10 grid, no special graphics just an inverted character for the cursor and a series of asterisks for the places.

I know this came from a school / college in Derby because of the letters header and was a prize winner in a competition held there. I saw the same program released the following year in the TRS 80 news. so thats as far back as I can remember it being around. Nowadays just about everyone knows it as "MineSweeper". Some of the older programs if they hadnt been handed out free where would we be today.
