I had an obscure machine ("Interact") in the early 80's that had an 8080, 16 kb of memory, and a cassette drive. There was an assembler for it. If I remember right, you read the editor from tape, edit and save your file, then read the assembler from tape, it reads the tape with your code and then writes the output to tape. I have no idea what the people ("Micro Video") producing software for this thing did, but I can't imagine they used this on-machine assembler. (The tape loading mechanism was basically blocks of address + data. They put loading screens on the tapes by populating video memory first.)
