If anyone has any broken/spare not used IIGS motherboards,
would you have any of the following IC's:

344S0046 VGC (Video Graphics Controller)
344S0066 CYA (Control Your Apple)
344S0050 FPI (Fast Processor Interface)
344S0049 (Slot Maker)
344S0048 (ADB GLU)legacy Keyboard/ADB Multiplexer General Logic Unit
344S0040 RTC (Real Time Clock)
344S0052 SGLU (Sound General Logic Unit)
344S0047 Mega II(Apple II Logic Core Controller)

The goal is to decapp the chips,
a die photo and then make a schematic from
the photo.

The results will be put on a website (project5474.org)
to use, study etc and gain more information
about the Apple IIGS.

I'd assume that any decapping project with the resources to do it right and to do all those chips would simply go buy a IIgs board or rig. You can get started faster as opposed to waiting for a donation.
