Based on Intel's 80286 microprocessor
running at 12 MHz, the PowerMate 286c is the entry-level system in NEC's new PowerMate C Series.
Some spreadsheets require only an 8088 microprocessor and approximately 512K of RAM, while others demand at least an 80286 microprocessor
and 1MB of RAM.
The personal computer hardware selected was a clone of an IBM PC AT model microcomputer running a 80286 microprocessor
at 12 MHz with a 40-megabyte hard disk.
This will cost about $800 more than an AT with an 80286 microprocessor
, but it will operate three to 10 times faster.
OCLC has announced that it will reduce prices by almost 20 percent on all models of the M310 Workstation (a 16-bit 80286 microprocessor
running at either 8 or 12.
While 386 PCs already run OS/2 (the operating system developed by IBM and Microsoft as a successor to MS-DOS), the current version is just as appropriate for the PC/AT's single-tasking 80286 microprocessor
and 16-bit architecture as for the more powerful 386.
The AT, using the Intel 80286 microprocessor
at speeds of 6 to 8 MHz, is about two to three times faster than a PC or XT.
The PC and XT use an 8088 or 8086 microprocessor, while the AT uses the 80286 microprocessor
Although some of the machines' CPUs could run Unix, even the 16-bit Intel 80286 microprocessors
operating at 25 MHz inside IBM PC/ATs and their clones did not provide true multitasking, so that engineering and other compute-intensive programs operated too slowly for some users' pace.
