check to see if
there's a memory wedge installed undneath the computer.
There was. Reading the
package carefully, it says Amiga 500 Deluxe. 512K
memory expansion pre-installed! Took it out and it still flashes the power
light. Thought there was no video for a second, but the A520 was just a
little loose. The power light flashes about once a second, and the screen
flashes every 10 seconds. Definitley something wrong.
It's been a while...but if I remember right, that sounds like the ROM
that's bad...I'll have to pull out some documentation and check...
