I wasn't sure exactly when the AS/400 came out except that around the late
80's there was comments about them being able to certainly outrun the 9370.
I figured they were somewhat close in time released. I know the 9370 was
released for production in '87 as the one I have was told to us as being
the very first sold. SN is (mumble)0001. We received it in late 1987.

Good description. I was thinking along the same lines when trying to
describe it to visitors. Indeed it is full of the custom devices. It is the
CMOS implementation of the S/370 architecture.
