25th Anniversary of the Personal Computer" 4215


re: ACM CAN; somebody mentioned the performance measures in the last issue of ACM-CAN. I just got v10n5 today in the mail.

Of course, but still not relevant to the point. Yes, it did. They expected to built 100 or so machines. The Apple...

"In the last issue of CAN we published a performance comparison of the mentioned that Intel had announced a successor to the 8086, called the 80286. Intel is sampling parts now and will ship 8MHz and 10MHz versions next winter. In addition to new instructions that support 32-bit data, the 286 has a spohisticated protection mechnaism reminiscent of MULTICS. The 286 also has a compativility mode to run existing 8086 programs."

...

"The bottom performance line as measured by these four small programs is that the newest version of the 432 (8MHz with 4 wait states) is almost as fast as a 5MHz 8086, while the 80286 leads the 432 by almost an order of magnitude. Furthermore, this fast machine (in 8086 compatibility mode) outperforms a 16MHz 68000."

re: 80286; "pipelined processor" with four parallel processing units. up to six times the performance of the 5Mhz 8086, bus interface up to 10 megabytes-second, samples of the 80286 available 3rd quarter this year. Price for 68-pin IC will be $237 in 100-piece quanbreasties. Also a iAPX Evaluation package with simulator, buttembler and demo programs for $950.

To: wheeler Hm, interesting article you sent.... I obtained advance information about the Intel iAPX286 .... it looks very interesting.... also have some data on the iAPX 86-30 and 88-30 Operating system processors.... this looks extremely interesting, and one can buttume that the 286 cannot be far behind in getting an operating system chip to go with it.... iAPX86-30 is a 2 chip processor, with 35 operating system processor primitives as instructions... things like job and task management, interrupt management, free memory management, intertask communication, intertask synchronization, and environmental control... It also supports 5 operating system data types: jobs, tasks, segments, mailboxes, and regions. Someday we'll be able to look back at the big RISC vs. CISC and wonder what all the fuss was about....
