re: http://www.garlic.com/~lynn/2014d.html#17 Write Inhibit http://www.garlic.com/~lynn/2014d.html#19 Write Inhibit both 3033 & 3081 were q&d machines done after failure of fs http://www.garlic.com/~lynn/submain.html#futuresys this details how 3081 was warmed over FS technology that compared very poorly with clone processors http://www.jfsowa.com/computer/memo125.htm there was enormous amount of hardware that was really expensive for the throughput it achieved ... as noted ... price had to be significantly adjusted to be somewhat price/performance competitive. the other issue was 3081 was originally going to be multiprocessor only ... while clone processors were coming out with increasingly fast single processor machines ... making single threaded operation even worse comparison. further aggrevating the problem was a major market segment was ACP/TPF (airline reservation system, transaction processing, etc) which didn't have multiprocessor support (so was stuck on 3033 or going to clone processors). there was all sorts of activities ... until a 3083 (3081 with one of the processors removed) was released ... about the only thing that could be said was it was a little faster than 3033. some old posts discussing 3083 http://www.garlic.com/~lynn/2010.html#1 DEC-10 SOS Editor Intra-Line Editing http://www.garlic.com/~lynn/2010.html#21 Happy DEC-10 Day http://www.garlic.com/~lynn/2010d.html#14 Happy DEC-10 Day http://www.garlic.com/~lynn/2010d.html#79 LPARs: More or Less? http://www.garlic.com/~lynn/2010e.html#23 Item on TPF http://www.garlic.com/~lynn/2010i.html#24 Program Work Method Question http://www.garlic.com/~lynn/2010i.html#78 IBM to announce new MF's this year http://www.garlic.com/~lynn/2010j.html#20 Personal use z/OS machines was Re: Multiprise 3k for personal Use? http://www.garlic.com/~lynn/2010n.html#16 Sabre Talk Information? http://www.garlic.com/~lynn/2011.html#19 zLinux OR Linux on zEnterprise Blade Extension??? http://www.garlic.com/~lynn/2011b.html#49 vm/370 3081 http://www.garlic.com/~lynn/2011b.html#70 vm/370 3081 http://www.garlic.com/~lynn/2011c.html#16 Other early NSFNET backbone http://www.garlic.com/~lynn/2011c.html#26 If IBM Hadn't Bet the Company http://www.garlic.com/~lynn/2011d.html#43 Sabre; The First Online Reservation System http://www.garlic.com/~lynn/2011f.html#49 Dyadic vs AP: Was "CPU utilization/forecasting" http://www.garlic.com/~lynn/2011f.html#60 Dyadic vs AP: Was "CPU utilization/forecasting" http://www.garlic.com/~lynn/2011g.html#7 Is the magic and romance killed by Windows (and Linux)? http://www.garlic.com/~lynn/2011i.html#77 program coding pads http://www.garlic.com/~lynn/2011k.html#84 'smttter IBMdroids http://www.garlic.com/~lynn/2011p.html#115 Start Interpretive Execution http://www.garlic.com/~lynn/2012f.html#59 Hard Disk Drive Construction http://www.garlic.com/~lynn/2012j.html#71 Help with elementary CPU speed question http://www.garlic.com/~lynn/2012k.html#10 Slackware http://www.garlic.com/~lynn/2012k.html#59 1132 printer history http://www.garlic.com/~lynn/2012k.html#86 OT: Physics question and Star Trek http://www.garlic.com/~lynn/2012l.html#90 Blades versus z was Re: Turn Off Another Light - Univ. of Tennessee http://www.garlic.com/~lynn/2012m.html#28 I.B.M.
