It is not "the IBM way". Back in the 1960s and 1970s, IBM strongly tended
to have everything clocked, sometimes using rather impressive circuitry.
The clock generator of an S/3 is astoundingly complex, and gets around
some of the uncertainty involved with one-shots and delays.

No, it was a real microcode machine. It could run a set of complicated
diagnostics on a disk, without bothering the channel. Real front panel, too.
