thanks all for the great and quick input. I'm far from a techy, so I'm proceeding very slowly... here's summary what I've found:
- as above, with both boards in slots recommended by Sun (Sun Memory Upgrade board in MEM 1, Apple 512 board in MEM2) I got the scrambled beehive screen and 2 beeps. On/off switch would switch on, but off was diabled (had to pull the pwr cord).
- I pulled the Apple board out of MEM 2, no change.
- I pulled the Sun board (Apple replaced in MEM 2): it tries to run tests but quickly I get 3 beeps and hard drive error 82. Lisa 2/XL Owner's guide says this is "Bad response from disk" error. However, I have a screen image (though it shows three horizontal bands of same image) and the on/off switch is fully functional.
- reveresed the placement of the boards: Sun to MEM 2, Apple to MEM 1 and got the same result (error code 82, etc..)
that's it for now... new screen shot at
