The 256k VRAM SIMM from my 475 is .75" tall and there's another .15" to bring it up to the level of the top of the PSU. Is there any tighter fit than in an LC case? If not, we've got .9" of PCB to work with for this. If we can't scrunch it down low enough to fit into the LC Case, what might be the next threshold for Max Headroom? ;D

I pulled the TrueVision NuVista*** out of the Magic Plastic Shoe Box of NuBus Goodness™ in order to give the ZIP28-P-400 Package a good look. These are TC524256AZ-10, But they're from Toshiba, so they're close enough for govt. work.

@trag: is there any particular reason why the ICs are flip-flopped on the 256k SIMM?

How many layers make up the VRAM SIMM PCB?

*** Thought I'd share this VideoCap/Editing Card Roundup article. ;)
