Can an EGA be used with a vintage-1985 Zenith Z-151 PC? I have such a
PC -- I have no way of knowing the version number of its ROM-BIOS, but
the "monitor" function is copyright 1984. I installed a VEGA Deluxe
EGA card (vintage 1986 from Video 7) and Multisync monitor (original
version) using the card and monitor configurations that Video 7
recommends for this specific PC. Turning on the computer then makes
the monitor come up with an orange border and a flashing white
center...no text or anything else. The keyboard is also unresponsive
(except to Ctrl-Alt-Del). (The monitor is influenced in SOME way by
the computer, since rebooting causes a transient rearrangement of
meaningless rectangles on the screen.) This monitor/adapter
pair works just fine on an ancient IBM PC with an updated BIOS ROM.
Any ideas? Zenith Data Systems has been no help (why should they
break tradition?). Since I don't have an account that can access the
newsgroup, please mail any response to me at this address:

I called their customer support number and told them what I had and what I wanted to do. They told me exactly what ROM I needed and how much it costs. Try to get IBM to sell you a ROM upgrade to the PC 1! The ROM was only about $12 by the way. I've always found Heath/Zenith more than reasonable to deal with; considering this is a mass market now.
