Re: mainframe vs mini, old and slow base and bounds, Why I've Dropped In

According to quadibloc  <quadibloc@gmail.com>:

On the other hand, the 4004 wasn't exotic. And since the Intel 8008
dates from 1972, I was wrong to think that 8-bit microprocessors were
nonexistent in 1973, so it was not correct for me to claim that it was
impossible for the IBM 370/115 to have used some sort of microprocessor
as its basis - even if I still would tend to suspect that it was
unlikely.

In that era IBM made their own chips, so there's no way they'd have used
an Intel microprocessor.

The ROMP project started in 1977.  I'm not aware of any IBM micros before
that.  They called the 5100's PALM a microprocessor but that was because
it ran microcode.  It was a dozen gate arrays, not a single chip.
