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. ================================================================================ Data Base Sort and Index Benchmarks Test 1 Test2 Sort 3911 records on one indexed field.
