          Management Overview           °°°   Review of Compaq DeskPro 286   °°°
                                        °°°                                  °°°
The Compaq 286 is  the  latest  in  the °°°              by                  °°°
evolutionary      cycle      of     the °°°                                  °°°
microcomputer.  This current generation °°°Bob McDuffee, Sysop, Grizzly King °°°
machine  utilizes   a   true   16   bit °°°                                  °°°
processor  as  well  as  16/8  bit  bus °°°         Hardware Review          °°°
interface.  This allows the INTEL 80286 °°°                                  °°°
microprocessor chip to perform at least °°°                                  °°°
twice as fast as the  IBM  XT  and  the °°°                                  °°°
Compaq Deskpro series.  The test system °°°                                  °°°
contained a 30 Megabyte hard drive,  10 °°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°
Megabyte  tape   backup   unit,   green °°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°
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.
