I received four 512 kB SOJ DRAM chips today from Utsource. My Piccolo SD64 was populated with only 2 MB, having four sockets free for additional 2 MB.
So, off with the lid of A4000 and snapping the memory chips in sockets. It was a matter of aligning the other side of the chip with the socket and pressing it in with the thumb while supporting the Piccolo from the bottom side with the rest of the fingers. No need of removing the card.
Then the lid back on and powering up the Amiga. Showconfig shows full 4 MB for the Piccolo.
Unfortunately, the additional memory doesn't give any better screenmodes than with 2 MB. 1024x768 hicolor seems to be the best that can be achieved.
