    SWV20 ˙˙is ˙a ˙driver for the NEC ˙V-Series ˙microprocessors ˙that 
    enables ˙the ˙8 ˙bit emulation mode of the device and ˙creates ˙an 
    environment ˙that ˙emulates a superset of the 8 bit CP/M.  ˙˙SWV20 
    runs ˙on any V20 ˙or V30 ˙equipped microcomputer ˙running ˙C/M-86, 
    MP/M-86, ˙Concurrent CP/M-86, Concurrent DOS-86 ˙or Concurrent PC-
    DOS.  ˙SWV20 ˙can operate as SW! ˙in a CompuPro environment and be 
    automatically invoked ˙by the system shell during program ˙search.   
    The ˙program ˙operating ˙in the 8 bit environment ˙has ˙access ˙to 
    nearly ˙all ˙of ˙the ˙function ˙calls ˙available ˙under ˙the ˙host 
    operating system, thus far more than normally available under CP/M 
    version 2.2.  
    
    Installation:
    

    To install SWV20, copy the SWV20.CMD file, the SWV20I.BAT file and 
    the *.INP ˙files onto your hard disk or second floppy and log onto 
    that drive. Next, make sure that sid86 ˙or ddt86 is present on the 
    a drive and that ˙it's ˙user number is 0 (root directory for a DOS 
    disk), and enter SWV20I swname [C] 
    
        swname is the command name to be used for the new SWV20
               use SW! for CompuPro.
    
        C      if entered (the [] means it's optional and should 
               not be entered) means this is for a CompuPro system.
    
    The batch file will create the file swname.CMD
    
    Now for all systems except CompuPro, ˙load each 8 bit program onto 
    your system and change the .COM extension to .CPM.  ˙For ˙CompuPro 
    systems, ˙˙copy the .COM program onto your system and run the 8BIT 
    utility ˙supplied with Concurrent DOS-816 ˙to set the proper ˙file 
    attributes.  ˙˙That's all there is to it.  ˙To run a program enter 
    the ˙program name you gave SWV20 ˙and the CP/M command line.  ˙For 
    example: to run the 8 bit program ddt on test.com and you gave the 
    program the name SWV20 ˙you would enter -  SWV20 DDT TEST.COM. For 
    CompuPro systems, ˙there is no need to enter the SW! ˙program name 
    just ˙enter ˙DDT ˙TEST.COM and the system ˙shell ˙will ˙internally 
    invoke ˙SW! ˙˙when ˙it detects that the request is for ˙an ˙8 ˙bit 
    program.  NOTE for CompuPro Systems: ˙When setting up the COMPUPRO 
    switch programs, ˙assume an 8085/8088 system  UNLESS you are using 
    SPU-Z ˙in ˙which ˙case ˙there is no need for ˙SWV20.  ˙˙There ˙are 
    additional ˙switch ˙programs ˙involved if you have ˙various ˙slave 
    processors ˙installed in your system.  ˙You can install SWV20 ˙˙in 
    place ˙of SW!8085 ˙that came with your system.  ˙You can use SWV20 
    with the CPU-8085/88 board or CPU-8086/87.
