 ORCHID'S JET 386

     *CUSTOMER REPORTS* of limited compatibility with Above Boards and
     Matched Memory Classic.  It is necessary to boot the system with the
     accelerator in 286 mode with an Above Board or Matched Memory Classic
     in the system.  If you boot in 386 mode, EMM.SYS will give "Error Msg.
     7" with older versions of EMM.SYS.

 MICROSOFT MACH 20

     *CUSTOMER REPORTS* of compatibility with Above Boards and Matched
     Memory Classic.

     For Expanded memory to work with the Mach 20 board, the MACH20.SYS
     driver must appear BEFORE the EMM.SYS driver in the CONFIG.SYS.  If the
     EMM.SYS driver is first, the expanded memory will not be recognized
     after the MACH20 driver has been invoked.

 MCT  SPEED DEMON

     We have mixed customer reports about compatibility with Above Boards
     and the Matched Memory Classic.

     One report saw the EMM message "a switch incorrectly indicates that you
     have an 8087."  This may have been due to the motherboard 8087 socket
     not being "plugged" (See the Accelerator General Information section).

     The board is compatible per another customer report.  However, switch
     #5 on the MCT board needs to be turned off when using an expanded
     memory board. This is documented in the Speed Demon manual.  Turning
     the switch off disables part of the cache memory.

 MICROWAY NUMBERSMASHER

     This accelerator was tested by Intel and found to be compatible with
     Above Boards and Matched Memory Classic.

     Note:  This accelerator seems to be the exact same board as the
     UNIVATION PC TURBOCHARGER.

 MOUNTAIN  RACECARD

     *CUSTOMER REPORTS* of compatibility with Above Boards and Matched
     Memory Classic.

     Note:  This apparently is the same board as the PC TECHNOLOGIES 286
     EXPRESS, which we have confirmed as being compatible with Intel Above
     Boards.

 ORCHID  TURBO 186

     Confirmed INCOMPATIBLE with Above Boards and Matched Memory Classic.
     This board is no longer being produced by Orchid.

 ORCHID  TINY TURBO 286

     *CUSTOMER REPORTS* of compatibility with current Above Boards and the
     Matched Memory Classic.  We also have reports of compatibility with the
     discontinued Above Board 286, PS/286, PC, & PS/PC.

     Tech Notes:  SETBOARD won't run in an XT with this board set in 286
     mode. There is a toggle switch on the Tiny Turbo that disables the 286
     and enables the 8088. Flip this switch and SETBOARD runs just fine.

     Some Tiny Turbos have a memory cache that must be disabled for an Above
     Board  to work.

     NOTE:  Be sure to tell SETBOARD and SOFTSET that you are in an 8088-
     based machine.

     This board has been used by 2 or 3 people in PCED and it works with the
     Above Board PC and PS/PC.  There have been problems found when using a
     math coprocessor on the Turbo board and also using an Above Board.  The
     problem can be solved by placing a dummy chip in the 8087 socket on the
     motherboard. Customers should call Orchid and ask for a dummy chip
     designed to work with the Tiny Turbo.

 ORCHID  TURBO 286

     *CUSTOMER REPORTS* of compatibility with current Above Boards and
     Matched Memory Classic.

 ORCHID  TURBO 286E

     *CUSTOMER REPORTS* that this full length accelerator board, (with cache
     memory), is compatible with current Above Boards and Matched Memory
     Classic.  We also have reports of compatibility with the discontinued
     Above Board 286, PS/286, PC, and PS/PC.

     Tech Notes:  The old TESTABPC does not work when the cache memory is
     active. We have no reports with the current TESTAB program.

 PC TECHNOLOGIES  286 EXPRESS

     *CUSTOMER REPORTS* of compatibility with current Above Boards, Matched
     Memory Classic, and the discontinued Above Board 286 and PS/286.

     Tech Notes: If SETBOARD cannot find the Above Board, try removing the
     286 express board and replace the 8088 temporarily.  SETBOARD should
     then run correctly.  The 286 Express can be forced to let the machine
     boot off of the 8088 which then allows SETBOARD to find the EEPROM.
     Change CONFIG.SYS to:

         DEVICE=EXPRESS.SYS 88

     This causes the machine to boot in 8088 mode.  Run SETBOARD, then drop
     the "88" parameter and the machine will boot 80286 again.

 QUADRAM  QUADSPRINT

     Tested here and found to be compatible with current Above Boards and
     Matched Memory Classic.

 SOTA 286 TURBO BOARD

     *CUSTOMER REPORT* of compatibility with current Above Boards and
     Matched Memory Classic.

 STB  PC ACCELERATOR

     *CUSTOMER REPORT* of compatibility with current Above Boards and
     Matched Memory Classic.

     We do have one report that the STB PC Accelerator software is
     INCOMPATIBLE with the optional QUIKBUF expanded memory print buffer.
     EMM.SYS installs without any problems.

 TITAN TECHNOLOGIES  ACCELERATOR PC

     Tested at Intel and found to be compatible with current Above Boards
     and Matched Memory Classic.

     Tech Note: If the 8087 socket on the turbo board is used, the
     motherboard coprocessor switch should be in the ON position.

 UNIVATION'S TURBOCHARGER PC

     *CUSTOMER REPORTS* of compatibility with current Above Boards and
     Matched Memory Classic.

     Tech Note:  It appears to be the same board as the MICROWAY
     NUMBERSMASHER which we have tested in the compatibility lab and found
     to work fine with Above Boards.

 VICTOR SPEED PACK 286

     *CUSTOMER REPORTS* of compatibility with current Above Boards and
     Matched Memory Classic.  Must disable their cache in order to run
     Setboard.

     Tech Notes: If the customer has a math co-processor installed on the
     Victor board, the math co-processor switch on the motherboard must be
     set for no math co-processor installed.  Indicating that a math co-
     processor is there may cause EMM.SYS to not load and display "The math
     co-processor switch on your computer's system board is not set
     correctly". The math co-processor on the Victor board will still
     operate correctly (passes CHKCOP) with the motherboard MCP switch set
     to off.

     This board is  apparently the same board as the PC TECHNOLOGIES 286
     EXPRESS, confirmed compatible here.

     Introduction

     Benchmarks are intended to give a standard measure of performance that
     can be used to predict how well application code will execute.  These
     benchmark programs should be representative of the intended
     applications.  However, the performance measured is often the combined
     characteristic of a given computer architecture and many other tightly-
     coupled system software and hardware constituents.  The memory and I/O
     subsystem design, as well as the operating system and the software
     development tools, may dominate the results and make the comparison
     difficult.

     This document contains performance measurements in both DOS and UNIX
     operating environment, which can be used as predictors of real
     application performance.

     The Intel RapidCAD Engineering CoProcessor

     The Intel RapidCAD Engineering CoProcessor, the newest member of
     Intel386 product family, is the highest performance floating-point
     upgrade for Intel386 DX microprocessor-based systems.  Manufactured
     using high speed CHMOS V technology, the Intel RapidCAD Engineering
     CoProcessor is a two chip set: RapidCAD-1 and RapidCAD-2.  The first
     chip, RapidCAD-1, replaces the Intel386 DX microprocessor.  It is pin
     compatible with the Intel386DX microprocessor and integrates the
     central processing unit (CPU) and floating point unit (FPU) on the same
     silicon die reducing the inter-chip communication delays.  Eliminating
     the communication overhead of transferring commands, data and results
     over the I/O bus between the CPU and the math coprocessor (MCP),
     enables exceptional floating-point performance.  The second chip,
     RapidCAD-2, is installed in the Intel387 DX Math CoProcessor socket.
     It provides hardware compatibility with the unmasked floating-point
     exception reporting in standard Intel386 microprocessor-based
     architectures.  The floating-point and binary coded decimal data
     formats fully conform to the ANSI/IEEE Standard 754-1985 for binary
     floating-point arithmetic.  The Intel RapidCAD Engineering CoProcessor
     is binary compatible with the Intel386DX microprocessor and the
     Intel387 DX, Intel387SX, Intel287XL and 8087 Math CoProcessors.

     Intel RapidCAD Engineering CoProcessor Performance Summary

     Benchmark results confirm that the RapidCAD Engineering CoProcessor
     runs floating-point code from 56 to 146 percent faster than the
     Intel386 DX microprocessor with the Intel 387DX math CoProcessor.  This
     exceptional floating-point performance translates into excellent
     performance improvement for applications which makes extensive use of
     the floating-point instruction set.  Application benchmarks show
     performance improvement averaging 30 to 40 percent, and as high as 67
     percent for 3D Studio and MathCAD. The Intel RapidCAD Engineering
     CoProcessor's exceptional floating-point performance translates into
     real time savings for the engineering professional using an Intel386 DX
     microprocessor-based system running CAD or scientific application
     software.

     Operating      
     System          AT&T UNIX System V/386 Release 4.0 Version 2.0

     Benchmark Tests:
     Standard benchmark tests were used to separately evaluate integer and
     floating-point performance.  DOS and UNIX standard benchmark tests were
     run.  All applications tested run under DOS or Windows.  Application
     performance was estimated using two kinds of tests.  A subset of the
     BYTE Application Benchmark Version 2.0 and the AutoCAD Benchmark Test
     Series Distributed by the AutoCAD Users Group of San Diego Version 1.1,
     were used as part of the application benchmark testing.  They run
     automatically, using the system clock to measure the execution time.
     For applications where an automatically running test was not available,
     such as AutoShade and 3D Studio, typical commands which use RapidCAD's
     floating-point capability were run and the execution time was measured
     with a stop watch.

     For each test there are two sets of results, one obtained with the
     Intel386 DX microprocessor and Intel387 DX Math CoProcessor, the other
     with Intel RapidCAD Engineering CoProcessor.  A performance index is
     calculated in each case showing the relative execution speed delta
     using the Intel RapidCAD Engineering CoProcessor vs. the Intel 386 DX
     microprocessor and the Intel387 DX Math CoProcessor.

     DOS Standard Benchmark Tests

     Dhrystone is an industry-standard benchmark test designed to measure
     system programming performance.  It includes weighted percentages of
     procedure calls, loops, integer assignments, integer arithmetic and
     logical operations.  The result is CPU speed expressed in
     Dhrystones/sec.  Sixteen-bit Dhrystone Version 2.0 and a 32-bit
     Dhrystones Version 2.1 were used.

     Whetstone is an industry-standard benchmark test designed to predict
     performance in a floating-point intensive enviroment.  It is a
     synthetic mix of floating-point and integer arithmetic, transcendental
     functions, floating-point array computations, and floating-point
     subroutine calls, based on statistical analysis of scientific FORTRAN
     programs.  The result is expressed in KIPS (kilo instructions per
     second).  Single and double precision 16- and 32-bit Whetstones were
     used.  In addition the Microway Whetstone benchmark was run to give a
     more comprehensive measure of floating-point performance in 32-bit
     protected mode.

     UNIX Standard Benchmark Test

     The SPEC benchmark Suite Release 1.0 consists of 10 FORTRAN and C
     benchmarks that are intended to be meaningful samples of applications
     which perform fixed- and floating-point logical and arithmetic
     operations as well as disk I/O in a technical environment.  Many of
     these benchmarks have been derived from publicly available application
     programs.

     The benchmark suite may be divided in two separate benchmark suites to
     distinguish between the integer and floating-point performance.  This
     allows for better performance prediction under different operating
     environments.  The integer performance represents a more appropriate
     instruction mix for commercial applications in a business environment.
     The floating-point performance can be used to predict the system
     performance in a technical environment for scientific and engineering
     applications.  The global SPEC index, SPECmark, is the geometric mean
     of all test results.  The SPEC integer index, SPECint, represents the
     geometric mean of the results for the four C programs.  The SPEC
     floating-point index, SPECfp, represents the geometric mean of the
     results of the six FORTRAN programs.

     DOS Application Benchmark Tests

     Generic 3D Drafting Version 1.1
     The model BEARING.3DD was used to execute a perspective change (VIEW,
     Perspect VP) with the coordinates 0,0,-25 and 350,400,400.  The elapsed
     time was measured with a stop watch.

     AutoCAD Release 11
     The BYTE Application Benchmark Version 2.0 test and the Benchmark Test
     Series Distributed by The AutoCAD Users Group of San Diego were used.
     This series of tests execute a typical mix of commands that might be
     issued by an AutoCAD user.  These tests measure the elapsed time using
     the system clock.

     AutoCAD Release 11 Advanced Modelling Extension (AME)
     A simple model was created (FLANGE.DWG) to test solids subtract, mesh
     and filled shade.  The elapsed time was measured with a stop watch.

     AutoShade with RenderMan Release 2.0
     The sample film KITCHEN.FLM was used to test full shade and RenderMan
     render.  The elapsed time was measured with a stop watch.

     3D Studio Release 1.0
     The sample models CITY.3DS, RACECAR.3DS, and STILLIFE.3DS were used to
     test the render function, with the following setting: Shading limit =
     Phone; Anti-Alias= High; Shadows = On; Mapping = On; Hidden Geometry =
     Hide; Render Output = Display.  The elapsed time was measured with a
     stop watch.

     Cadkey 386 Version 4
     To measure performance with the standard drawing functions an array of
     1000 ellipses was first drawn and then deleted.  To test the
     performance of advanced solid functions the sample model SOLID4.PRT was
     used.  A complex process performning solid boolean operations (solid
     subtraction and plane sectioning), mass properties and a smooth shading
     followed by the rendering (with Shading = Phong) of the resulting image
     were performed.  The elapsed time was measured with a stop watch.

     MicroStation PC Version 4.0
     The sample ORBITER.DGN model was used for hidden lines removal, smooth
     shading, phong shading, stereoscopic rendering and a zoom out.  The
     elapsed time was measured with a stop watch.

     Upfront Version 1.0
     The sample drawing LIBRARY.UPF was used and two view change tests were
     done: from initial view to Birdseye and back.  The elapsed time was
     measured with a stop watch.

     Mathematica 2.0 for DOS 386/7 and Mathematica 2.0 for Windows
     The execution time of Plot3D[10 sin[x+Sin[y]], {x, -10, 10}, {y, -10,
     10}, PlotPoints -> 80] was measured with a stop watch.

     MathCAD 2.50
     The BYTE Application Benchmark Version 2.0 test was used.  It
     calculates a convolution integral and evaluates an iterative function
     system.  This test measures the elapsed time using the system clock.

     PC-Matlab Ver 3.5g
     The BYTE Application Benchmark Ver 2.0 test was used.  This test
     performs a mix of matrix and signal processing operations.  This test
     measures the elapsed time using the system clock.

     SPSS/PC + V4.0.1
     A statistics example with 1473 cases was used for descriptive
     statistics (means) and a graphic representation with Harvard Graphics.
     The elapsed time was measured with a stop watch.

     STATGRAPHICS Ver 4.0
     Three randomly gneerated 1000 samples series were used for summary
     statistics (STATS) and multiple regression.  The elapsed time was
     measured with a stop watch.

     Lotus 1-2-3 Release 3
     The BYTE Application Benchmark Ver 2.0 test was used.  The test loads
     and recalculates a spreadsheet based on the Savage formula, then it
     runs a macro that performs a binary goal seek.  Additionally, a large
     block of text data is loaded, copied and then saved.  This test
     measures the elapsed time using the system clock.

     Excel Version 3.0
     The BYTE Application Benchmark Ver 2.0 test was used.  The test is
     similar to the one for Lotus 1-2-3.  It loads and recalculates a
     spreadsheet based on the Savage formula, then it runs a macro that
     performs a binary goal seek.  This test measures the elapsed time using
     the system clock.

     Note:  The loosely copuled internal architecture makes RapidCAD more
     sensitive to wait states than Intel386 DX CPU.  Therefore in systems
     without cache and more than three wait states for memory accesses, the
     integer performance of RapidCAD becomes lower than the integer
     performance of Intel386 DX Microprocessor.  However this is not likely
     to occur, since almost all Intel386 DX microprocessor-based PCs have
     cache in their configuration.

     Additional wait states in the MCP I/O cycles may considerably increase
     RapidCAD's floating-point performance relative to Intel386 DX
     microprocessor and Intel387 DX Math CoProcessor.
