I installed my new aca 1233n on my aca500plus with x surf 500,but it will not boot. It give a green screen with what appears to be a list of memory location. Am I doing something wrong, or is something else amiss. Love your products, just looking for help, not complaining. The machine itself is an Amiga 500 with indevision installed. Tried a couple of PSU, one a new one.
