Management Overview <20><><EFBFBD> Review of Compaq DeskPro 286 <20><><EFBFBD>

<20><><EFBFBD> <20><><EFBFBD>

The Compaq 286 is the latest in the <20><><EFBFBD> by <20><><EFBFBD>
|
|||
|
|
evolutionary cycle of the <20><><EFBFBD> <20><><EFBFBD>
|

|
|
microcomputer. This current generation <20><><EFBFBD>Bob McDuffee, Sysop, Grizzly King <20><><EFBFBD>

|
|
machine utilizes a true 16 bit <20><><EFBFBD> <20><><EFBFBD>

|
|
processor as well as 16/8 bit bus <20><><EFBFBD> Hardware Review <20><><EFBFBD>

interface. This allows the INTEL 80286 <20><><EFBFBD> <20><><EFBFBD>
|
|||
|
|
microprocessor chip to perform at least <20><><EFBFBD> <20><><EFBFBD>
|
|||
|
|
twice as fast as the IBM XT and the <20><><EFBFBD> <20><><EFBFBD>
|
|||
|
|
Compaq Deskpro series. The test system <20><><EFBFBD> <20><><EFBFBD>
|
|||
|
|
contained a 30 Megabyte hard drive, 10 <20><><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD>

text/graphics display monitor, 640K of
|
|||
|
|
RAM and a 1.2 Megabyte floppy disk drive. Throughout the test the machine
|
|||
|
|
performed without fail. All software currently approved for purchase by the
|
|||
|
|
DPIC ran without modification on the 286. This demonstrates that the machine is
|
|||
|
|
fully compatible with the current installed base of microcomputers while
|
|||
|
|
offering efficiency enhancements (clock speed of 8.00 MHZ compared to 7.2 MHZ
|
|||
|
|
for the DeskPro) and, expanded memory and secondary storage options. Several
|
|||
|
|
times during the test the high density disk drive was used to format and write
|
|||
|
|
the standard 360K diskettes to transfer data to an older PC, and performed
|
|||
|
|
flawlessly!

|
Objectives
|
|||
|
|
|
|||
|
|
Given the desire to off load the VM machine of `non-mainframe' systems as much
|
|||
|
|
as possible, the need for a machine capable of handling large data files (PC-SAS
|
|||
|
|
or PC-FOCUS for example) with reasonable speed and yet is compatible with even
|
|||
|
|
the first IBM PC's is apparent.
|
|||
|
|
|
|||
|
|
Evaluation
|
|||
|
|
|
|||
|
|
Benchmark testing was performed to allow comparison between the Compaq Deskpro's
|
|||
|
|
currently in use at StorageTek and the new generation of Compaq 286 Deskpro's.
