I was lucky enough to get a Amiga500 with an 8372a Angus as factory. I wish to increase my CHIP ram to 1 meg. I have read the notes on how to change the traces from ANGUS to 68000, but upon inspection of my motherboard, I noticed a interesting feature. That is my 512k chip ram is 256k x 4 dram, with spaces between the 4 chips for 4 more chips of the same type. That is the holes and traces exist for 4 more 256k x 4 drams. My question is this, Can I just add the chips and associated capac- itors, or do I have to change the ANGUS to 68000 trace from 52 to 47 still ? Also since I got the standard intro to amiga book, my schematic is out of date, What is the proper rate (in volts and farads) of the capacitors ? By the way my motherboard is a rev6a. Many thanx in advance, Jay Reher
