IBM 9370 Mainframe Specs?

[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) 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...
