[net.micro.pc] Z-100 Extended Video

SJOBRG%MIT-OZ@MIT-MC.ARPA (01/29/84)

The November 1983 issue of Microsystems magazine carries a review of the
Zenith Z-100 computer system.  The review states:

    The video board allows an alternate display format, which
    could be used to provide an interlaced display of 640 by
    525 pixels, but no information is provided on specific
    programming for that purpose.  (p. 100)

I have often lamented the fact that the IBM PC only goes up to 200
lines in high-resolution mode when 480 would have permitted a square
aspect ratio (so important when dealing with digitized images).  Does
anyone have any information about this capability in the Zenith
machine?

Thanks.
