My friend has a early version of Eagle pc compatible with a harddisk,
a monochrome display adapter. We try to upgrade it with a EGA display
controller card. After trying with a lot of combinations, there is
nothing show up in the screen at all. We have no documentation describing
the meaning and function of various jumpers on the Eagle mother board.
Its lay out is very different from a PC-XT (or XT clone). Please return
with E-mail to :   timok@utcsri

Thanks in advance.
