something like:
[9370]
Mainframe? Yeah, I guess it could still be called
that because of its
intended application to handle a whole enterprise plus it is a CMOS
implementation of the good ol' S/370 iron. However, its performance was
rather poor compared to IBM's newer AS/400 family launched about the same
time as or just before the 9370.
I know that this is not very helpful but I think the 9370 was announced in
1987,
since I saw stuff on it during my summer job at IBM that year, and not the
previous year. I never saw anything about the AS/400 at that date, nor even
during my summer job the following year (although that latter was building
cash
dispensers, so I was a little out of touch with the
rest of IBM)
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.
Anyway, at the time I regarded it as a mini-mainframe. Mini because it didn't
need a separate computer room (and was advertised on this basis), mainframe
because it was still huge and packed full of IBM custom hybrids (which were
probably built of IBM custom chips), as well as the 370 compatibility...
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.
