This would probably only interest hardware hackers ...

I opened up an old 512KE Mac to see what the DRAM chips were.  I found out
that there are 2 rows of 8 socketed chips in each row.  The chips are 256K bit 
DRAM chips.

What I am wondering about is if it is possible to just take those 256K bit
chips out and plug in 1 Mbit DRAM chips to upgrade the RAM to 1 meg!!!!

Any ideas?
