Looking at the old games - anyone else remember the old DEC graphics terminal (circa 1980). We had one at the educational establishment I frequented in those days, hooked to a PDP-11 running Unix 7, and it had the "Moon Lander" game which amazed us as it was graphical. You used the light pen to control the moon lander's decent & if you got on the moon without mishap the astronaught came out & popped into the Macdonalds next door for a burger. One of the profs was so good he could loop the loop in the moon lander on the way down.
In 1981 we upgraded to a VAX with BSD Unix (pre V4 I think) and it came with a game called "Space Invaders" that you could play on a standard ascii terminal, wonder what happened to that?
