The information in this article applies to:
- Microsoft Windows 3.1
- Microsoft Windows 3.11
This article was previously published under Q88547 SYMPTOMS
Tandy technical support has confirmed that you may see white spots on
your display when you use Microsoft Windows 3.1 on a Tandy 4825SX and a
4850EP after you have upgraded the video memory.
CAUSE
This problem is caused by an incompatibility between some of the
motherboards and the Intel 70 nanosecond video RAM chips. If, after
upgrading the video memory, you see white dots on the screen in Windows
3.1, then look at the main logic board next to the CMOS battery. If the
word "WAVE" and a up arrow are stamped on the motherboard, then the problem
is probably with the video RAM upgrade chips. The video RAM chips that
produce the error are Intel 70 nanosecond chips.
RESOLUTION
These Intel 70 nanosecond chips should be replaced with either Intel 60
nanosecond or Micron 70 nanosecond chips.
To correct this problem, contact Tandy technical support for replacement
video RAM chips.
