[comp.sys.amiga.hardware] Memory Expansion

vik@lynx.uucp (Vikram Sohal) (08/15/90)

Does anyone know about the side effects of expanding the A500's memory
beyond 1 Megabyte? I have heard that certain methods cause problems
for programs expecting contiguous chunks of RAM beyond 512K. 
Any recommendations as to what advantages/disadvantages internal or external
memory expansions offer?

I was curious about adding a lot of 256k bit drams to my A500. Now I have
read the Hardware reference manual and got some brief information on how
to interface them, but I am looking for something perhaps a little more
informative. A little more descriptive. Like, what type of Dram controller
chips to use and if I need to use PALs and where I might get PAL equations.

How to boards "pseudo auto config" ?

Responses would be appreciated....
