in the wake of FS failure ... some past posts http://www.garlic.com/~lynn/submain.html#futuresys there was a made rush to get stuff back into the 370 product pipelines (370 efforts were being killed off &/or suspended during the fs period) ... including using warmed over FS tech for 3033&3081. i was told that one reason 370/158 was chosen for 303x channel director was incremental manufacturing cost of 158 was $1000. A 3031 was 158 engine with 370 m'code and w/o 158 integrated channel microcode plus a 2nd 158 engine with integrated channel microcode (& w/o 370 microcode). A 3032 was 168-3 with 168 external channels replaced with 303x channel director (158 engine). A 3033 was 168-3 logic remapped to 20% faster chips and one or more 303x channel directors. about the same time there was an article that the incremetal manufacturing cost of a automobile was four hundred and some odd dollars. Intel has spent $5B on new fab for the latest 14nm chip technology. If they sold only one chip they would have to add the $5B fab cost to the price of the chip. If they sell a billion chips, they only have to add $5 to the price of each chip (and they have to recover the fab cost before it is obsolete and they have to move to a new fab with the next generation of chip technology). this somewhat comes up in the discussion about ibm selling its chip fab business ... and possibly nobody wanting to acquire the east fishkill and burlington fabs. in an (linkedin) ibm employee discussion, somebody pointed out that ibm hasn't had new investment in those fabs for years. Part of the implication of moore's law is that there is new chip technology generation every couple years requiring brand new fab technology (and typically brand new fab). recent references: http://www.garlic.com/~lynn/2014f.html#33 upcoming TV show, "Halt & Catch Fire" http://www.garlic.com/~lynn/2014f.html#43 upcoming TV show, "Halt & Catch Fire" http://www.garlic.com/~lynn/2014f.html#54 IBM Sales Fall Again, Pressuring Rometty's Profit Goal http://www.garlic.com/~lynn/2014f.html#69 Is end of mainframe near ? http://www.garlic.com/~lynn/2014f.html#80 IBM Sales Fall Again, Pressuring Rometty's Profit Goal http://www.garlic.com/~lynn/2014h.html#14 Check out IBM Said Near Deal With Globalfoundries for Chip-Making - Bloomberg -- virtualization experience starting Jan1968, online at home since Mar1970 ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
