║ Classic Above Board Accelerator Board Compatibility: L-Z ║
║ ║
╚═════════════════════════════════════════════════════════════════════════╝
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.

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.
