The address line buffers (UC3 / UB3) were changed quite early on.

The video RAM buffers (UE7 / UE8) were replaced as part of the process of fixing the video section.

The buffers local to the DRAM (UI10 / UI11) have not yet been changed.

The buffers separating the CPU data bus from the buffered data bus (UE9 / UE10), currently under examination, have not yet been changed.
