My guide explains this a little bit:

Yes i know, the guide is very clear and easy to follow but as i can understand the eprom should be placed on the right side of the donor card but for the 27c322 (pin32 is a20) but for 27c160,800 is Byte vpp and for 27c400 pin 31 is byte vpp.On my board pin 31 is connected to pin 21 (VCC) so in order to use the 32mb eprom on my donor i had to cut board pin31 trace and solder eprom pin a20 to cart connector b9.
