The keyboard in assembly is KBD

[culchie]

I considered not bothering to make the assembler program as I didn't think there was anything to be learned from making it.

The main thing I learned from it was that it's more difficult than it looks.

In particular how to represent labels in the symbol table.

Converting decimals to binary wasn't as trivial a programming task as I thought it would be either.

Also you needed to go through the text with a fine tooth comb to the reserved word for keyboard!
