I understand that the atari 800XL can be upgraded to 256K by replacing the 64K chips and doing some appropriate address decoding with the ACIA. I was wondering if anybody could direct me to an appropriate source to find the nescessary information or tell me what is required. I am a 4th year computer engineering student so technical descriptions would be just fine. Thank you Dave Amundson
