Not VRAM upgradeable. The 512K VRAM is sufficient to run a 5300c screen 
though you'd have to swap. It'll do 16 bit at 640x400 (not 480). 1MB from 
the 5300c/ce logic board is required for this.

See the graphic of all the 5300 logic board configs at my page at:

Yes. I don't think any PB VRAM is upgradeable, except for external 
monitors with separate cards driving them.

You'd need the Focus Lapis PDS card which replaces the Apple video card 
(the card's VRAM for ext. is entirely independent of the internet 
soldered VRAM). If you find one cheaply enough, it'll give you '000s 
colours on an external.
