Can anyone help me obtain a schematic and/or technical
information for the IBM EGD model 5154. Mine has developed
a problem. When a program switches between display modes my
EGD often start writing text 2/3 of the way across the screen
and wraps around to the start of the line. Switching the
display off and back on usually cures the problem. I suspect
that the horizontal scan rate selector circuit is defective.
IBM does not repair EGD's on an individual basis but charges
approx. $400 for an exchange.
