Please note: We have sourced these chips from many places, so you may receive a chip that looks different. Some of ours chips have been cleaned and/or remarked, or may be dirty from being in storage for many years, but ALL our chips are fully tested before sending.
The 6569 VIC-II chip is the graphics chip that made the C64 famous, supporting different graphics modes at different resolutions as well as sprites in a way no other machine at the time could.
Although the VIC-II doesn't very often stop working, it can cause faults such as:
Blank screen of a random colour
Blank screen with no sync (monitor will say "No Picture").
Black screen (also a symptom of many other things).
