I've often contended that, in part, John did 801/risc as reaction to the horrible complexity in Future System ... misc. past posts http://www.garlic.com/~lynn/subtopic.html#futuresys 79-80 there was big push to move that vast array of internal microprocessors to 801/risc ... microprocessors in low&mid range 370, control microprocessors, the as/400 (merged followon to s/36 & s/38), etc. these were in large part Iliad chips of one form or another. for various reasons, the efforts faltered and you saw some number of the engineers leaving to do risc at other vendors. ... misc. old 801 email http://www.garlic.com/~lynn/lhwemail.html#801 The 4331&4341 followons (4361&4381) were going to be Iliad (801/risc) ... I helped with whitepaper that derailed those efforts. An issue was that circuits were getting small enough that it was possible to directly implement much of 370 directly in hardware (rather than having to resort to the microcode implementations of previous generations). one of the efforts was ROMP chip for what was going to be the displaywriter follow-on ... however that got canceled (lot of word processing was moving to personal computing). the group looked around and decided to retarget it to the unix workstation market. they got the company that had done the unix port for ibm/pc (pc/ix) to do one for romp ... and it came out as pc/rt and aix. followon to ROMP was RIOS chipset for rs/6000. recent post about los gatos lab doing "blue iliad" ... first 32bit 801 ... never got much past sample chips: http://www.garlic.com/~lynn/2013i.html#0 By Any Other Name past posts mentioning 801, risc, fort knox, iliad, romp, rios, power, power/pc, etc http://www.garlic.com/~lynn/subtopic.html#801 however, there is the tale of ACS360 ... which ibm management shutdown because they were afraid that it would advance computing technology too fast, and they would loose control of the market. http://people.cs.clemson.edu/~mark/acs_end.html above also discusses features from ACS360 showing up more than 20yrs later in ES/9000. other recent posts referencing ACS360 http://www.garlic.com/~lynn/2013e.html#10 The Knowledge Economy Two Classes of Workers http://www.garlic.com/~lynn/2013e.html#18 What in your opinion is the one defining IBM product? http://www.garlic.com/~lynn/2013e.html#26 The Big, Bad Bit Stuffers of IBM http://www.garlic.com/~lynn/2013e.html#52 32760? http://www.garlic.com/~lynn/2013g.html#1 A Complete History Of Mainframe Computing http://www.garlic.com/~lynn/2013g.html#10 SAS Deserting the MF? http://www.garlic.com/~lynn/2013h.html#13 Is newer technology always better?
