> then they essentially bootstrapped a foolproof, checksummed machine-code editor I remember that I copied a short program in BASIC that you had to run in order to type in the machine code part of the main program you were typing. It would sound a bell if the checksum had no error, otherwise you would hear a buzz sound. > and, somewhat regrettably, cut out the source-code middleman. The programs I typed in had parts in BASIC and other in machine code. I just wish the machine code parts used the instruction mnemonics instead of the actual instruction byte code. It definitely would have been more educational to see instructions like LDA, SDA, CMP, JSR, etc instead of the actual number values.
