Up and Running!

- After solving the tapeload issue I began to load the old cassette tapes from the 80's.
Talk about nostalgica!...
Self-made games such as Quest (inspiration from Byte magazine), Star Wars, Dogfight, TicTacToe, the Knight Chess Problem, Lunar Lander and Nimble (user vs computer, the latter hard to beat).
And the "File Manager", in pure machinecode, resident in the safe area of RAM.
This routine searched for fileheaders on tape, then loading. Slow, but it worked!
I was very proud achieving this I remember...No assembler used, just pure hex....!
Later, a lot of half-done projects were also discovered on some tapes, eg a wordprocessor as well as other games.
