    That figure is way off... PATHWORKS has never required "300 - 400 Kbytes"
    of physical memory, as far as I can remeber. It probably was something
    like closer to 200KB in the past.
    
    Today:
    
        PATHWORKS for DOS V4.1 (DECnet, Ethernet, all components/drivers)

            SAVE             1K                  1K
            -------------------------------------------------------

        Choices you may make, that affects memory consumption:
        
                Native or NDIS datalink
                Basic or Enhanced Redirector
                LAD/LAST used or not
                LANSESS used or not
                LAT/CTERM loaded automatically or dynamically
                RCV loaded or not
                MSCDEX needed or not (for InfoServers or standalone)

        Also there are a number of parameters that affect the size of the
        components (like, e.g., varius NCP parameters have a direct affect
        on DNNETH (a.k.a. DNP).
                        
        When UMB's (Upper Memory Blocks) are available, the conventional
        memory requirements are even further reduced, when they are 
        loaded "high".
        
        In an optimal situation (386 or better, EtherWORKS board in 32KB
        mode, native datalink, no SCSI, Basic Redirector, DOS 5, good memory 
        manager, some experience) you should be able to achieve 0K (or very
        close to 0K) of conventional memory consumed for PATHWORKS for DOS.
        
        With a PC with no EMS, no UMB's (XMS), no memory managers, the
        conventional memory usage with V4.1 is something like 98K.

    If possible, at DECUS (U.S.) attend Chris Lord's memory seminars; you'll
    find out everything you ever wanted to know - or more - about PC memory
    management with or without PATHWORKS.
    
    Or, at least, get MEMORY.ZIP from our CompuServe forum DECPCI. (No,
    there is no Internet, anonymous FTP site that I know of, where this
    file is).
