1.1     ! root        1: .TH XVS100 8 "26 August 1985" "X Version 10"
        !             2: .SH NAME
        !             3: Xvs100 - X window system VS100 implementation notes
        !             4: .SH DESCRIPTION
        !             5: .PP
        !             6: The VS100 implementation of X was the first, and is complete.
        !             7: Many of the X output operations are in fact modeled on the interface provided
        !             8: by the VS100 firmware.
        !             9: The VS100 is a monochrome display, 864 bits high and 1088 bits wide.
        !            10: The firmware we are currently using is version #235.
        !            11: .PP
        !            12: Cursors can be any size up to 64x64.
        !            13: Tiles can only be 16x16 in size.
        !            14: Brushes can be any size, but the current firmware draws wide lines about an
        !            15: order of magnitude slower than 1x1 lines.
        !            16: Off-screen storage is limited to that provided in the VS100 itself; no attempt
        !            17: is made to use DMA access to VAX memory for fonts and such or to dynamically
        !            18: shuffle data back and forth.
        !            19: .PP
        !            20: The keyboard is controlled by the VS100 firmware.  Unfortunately, with the
        !            21: current firmware, the keyboard only gives up transitions for the Control,
        !            22: Shift, Lock, and Meta keys, so chord applications won't work.
        !            23: .PP
        !            24: At system boot, for some reason the first three attempts to down load the
        !            25: firmware fail.  Thus, a VS100 won't become active until about 45 seconds
        !            26: after other terminal lines activate.
        !            27: Power-cycling a VS100 will cause the X server to restart.  The down
        !            28: problem doesn't occur in this case, but typically a
        !            29: 3 minute TCP CLOSE_WAIT will occur.
