My first contact with computers involved punched paper tape - one roll of it for the program and another for the source data. I think that was in the late 60's.
Then in the 80's I got a Commodore Plus4 to play with. A luxury machine! It had two extra address lines, so it could do bank switching between four 64K blocks.
I did all sort of daft things with it. A machine code program so that I could do screen dumps to a 7 pin dot matrix printer. A spell check program to use with the word processor, but I had to build up the dictionary which, with data compression, could hold about 10,000 words in RAM.
And the piece de resistance, I wrote a compiler for the Commodore Basic. I have no idea now how I did it!
Computers were much simpler then.
