[comp.sys.amiga.hardware] Alegra ram board a1000 h

-> I have an ALegra RAM board that I bought used from a friend. It has
-> 512k and is supposedly upgradable to 2 MB's with 1m x 1 drams(which I
-> have).
-> The board is made by Access Associates, and is for the A1000.
-> The problem I have is that it won't recognize the RAM when I put the
-> 2mb's in it. And since there is no jumper to change the config of the
-> board, It only recognizes the first 512k of the 2MB's.

   You need to change two PALs in the unit to get it to recognize the 2 
megs of RAM. Findig the PALs may be difficult, since they have not been 
made for years. I got my set (about 3 years ago) from Abel's. You never 
know, they may have a set in a dusty corner.
