In the early 1960s disk drive were expensive and small; running from tape was the norm. By the time IBM shipped S/360, disk was much more affordable. I never ran into a TOS shop/

I have done a LOT of assemblies from trays of cards. In DOS/360, in 1970, when I did so, COPY libraries were always on disk. This was even before spooling in DOS, so the assembler literally read from the card reader (well, called an access method that read card-by-card from the card reader). There was a b@st@rd stepbrother of DOS called TOS (yes, the T stood for Tape) that had its SYSRES on tape, believe it or not. I guess its operation was a sight to behold, but I never used it personally and have no idea about its assembler mechanics.

How did the assembler originally work, back when punched cards were used? I don't really know.
