Pin 33 definitely appears to be tied to something in @mizerable 's photo. Must be power plane.
These may help? To me, looks like it's to the power plane, on the chips it's "v88"
Yeah, via the internal GPU.Are you doing that on the internal video, or a video card? What resolutions and colour depths are you getting?
It likely would have been BYTE# on any ROM in that form factor, since they would be following the JEDEC standard.I wonder why? The ROM chips have a Byte# pin? The ROM chips use 33 as a another power pin? Apple left the option to put programmable chips on those modules?
