The DOS/360 and TOS/360 Assembler (D) had a 16 KiB design level and,
while it exceeded that, I don't believe that it exceeded it by that
much. Similarly, the OS/360 Assembler (E) and (F) had 32KiB and 64KiB
design points; again, they didn't exceed those sizes by that much.
Perhaps you meant that Assembler (F) required a 96 KiB machine.

Soem of which had been developed at SLAC.
