Upon the date 11:53 PM 10/28/99 -0600, Mark Gregory said something like: Hello Mark, I've got one of these systems. A 9370 model 60 (uses a 9375-60 processor.) This one is purported to be the first regular production unit sold to a customer (my ex-employer). Serial no. (something)0001. Not near the machine presently. I have not successfully gotten it running at home _yet_. I'm not an expert at IBM big iron but have been learning bits here and there. I've not had it turned on to continue with run-up since late '97 because of "minor" events in our homelife (moving to a new house, unemployment, etc.) The IPL fails for reasons unknown so far. I got the PS/2 Model 30 console with it plus all its floppies and a heap 'o hardware docs. 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 think production stopped in 1990. The AS/400's of the time could whip the 9370 and it apparently didn't sell all that well from what I can tell. Mine came off the line in late-'87 as I recall since that's when the company completed the new computer center at a separate downtown building. The 9375-60 processor in mine weighs 130 kilos. Had to completely dismantle it so I could move it and carry it downstairs. Much too large to simply remove the boards and PSU's and carry it alone. No, typically the SNA 3270 network. Single phase 240V. I use a 30A double pole breaker off my panel. The cabinets were too big to stuff down the basement stairs at our old house. Even this house we recently moved into _just_ misses having the basement entrance off the garage big enough to allow the cabs to squirt through. Indeed they are big and clumsy to handle, over 300 pounds stripped down to the paint. Conditions out in our uninsulated garage preclude storing it out there because of the Fall/Winter/early Spring weather around here (dampness at times, large temp. swings too). So I didn't bring the cabs home (had to scrap 'em) and just have the components setting in a heavy-duty 19" equipment rack on wheels :( Western Canada . . . Dang. I wish you were close to me (basically just inland across Lake Erie from ON.) Then I might attempt getting it, finding a big bucket of grease and trying to get a rack squeezed down into the basement here. Several of us discussed the 9370's on this list back in early 1998 (February?) Check the ClassicCmp archives under '9370' at <http://www.heydon.org/kevan/mlists/classiccmp/> for the months around 2/98. I *need* OS docs for this machine too. I understand it has VSE of some sort (recall I haven't gotten 'er up and runnin' yet). Probably been updated to the mid-1993 timeperiod releases.
