MODULE DESCRIPTION
1.1 INTRODUCTION
TheXVME-682VMEbusPC/ATProcessorModule isdesigned tocombine the high-
performanceandruggedizedpackaging oftheVMEbuswiththebroadapplication software
base oftheIBMPC/ATstandard.Themodule is fullyAT-compatible,capable of running
standardPC/AT software.
TheXVME-682 iscomprised oftwoVMEbus-compatible,6U(double-high)cards:the CPU
Moduleand the I/OModule. Thisuniquetwo-cardarchitecture isdiscussed later in this
chapter.
TheXVME-682comes in fourversionsdependingonthememorydesiredandthe mounting
locations oftheboards relative tooneanother.Thetwomemoryand configuration options
canbeselected inanycombination. Thisprovides for four versions.
ThememoryoptionsavailableontheXVME-682areeither1 or4M RAM.
Thelocationoptiongivestheuserthe ability tomounttheCPUand I/Oboards together or
innon-adjacentVMEbusbackplaneslots.Whentogether,thesharedPC/ATsignalsare passed
betweentheboards viaaxx-pinconnector. Inthenon-adjacentversion,thePC/AT signals
arerouted viatheVMEbusP2 backplane.

1.3 XVME-682TWO-CARD ARCHITECTURE
1.3.1 TheXVME-682CPU Module
TheXVME-682CPUModuleusesan80286microprocessor withsoftware-selected speeds of
10,8or6MHz.Memory isavailableaseither1Mbyteor4Mbytedual-portedRAM(with one
waitstate).BoththeVMEbusandPC/ATinterfacesresideon thisboard.Other XVME-682
CPUfeatures include:
•An optional80287mathco-processor
•FullIBMAT motherboard features
•VMEbusmaster,slaveand interrupthandler interfaces
•A"RealModeWindow"whichallows allVMEbuslocations tobeaccessed while the
processor is in"real mode"
•Control/Status registers
•WatchDog Timer
•VMEbus"Slot1" functions
•Threesoftware-configurableports(2serialand1 parallel)
•IBMPC/ATbusaccessibility viaVMEbusP2connector oroptionallocal connector
1.3.2 TheXVME-682 I/O Module
TheXVME-682 I/OCardprovidestheinterfacebetweentheXVME-682CPUcardand the
floppydisk,hard diskandgraphics controller.Featureson theXVME-682 I/O Module
include:
•EGA,CGA,MDA,andHerculesgraphics support
•256K ofvideo RAM
•IBMPC/AT-compatibleWinchesterandfloppydisk controller
•Control ofup totwoWinchester-typeharddisk drives
•Control ofup totwofloppydisk drives
1.3.3XVME-682BusSignal Interfaces
TheXVME-682CPUand I/Oboardsareunited viaalocalbus.ThisallowstheCPU board
tocommunicate directly withthegraphics ordisk-controller circuitry without tyingup the
VMEbus.VMEbussignalsarecarriedbytheP1 connector.
TheXVME-682 I/OmodulerequiresthePC/XTbus forproperoperation of its graphics
controller circuitry. Italsorequiresthe fullPC/ATbus foroperation ofthedisk-controller
circuitry.
ThePC/XTbus isplacedonRowsA &C oftheVMEbusP2backplane connectoron all
versions oftheXVME-682.Theremainder of thesignalsrequired forthePC/ATbus are
placedeitherontheRowB oftheVMEbusP2backplaneconnector, orona local connector
(P3).
TheXVME-682/1andXVME-682/3aredesigned toallowuse ofa32-bitprocessor inthe same
backplaneastheXVME-682.Thetables inAppendixCdescribethesignalsassignedfor the
variousoptions ofthe XVME-682.
