Mac128:

Thanks for your reply, I will pursue further.

I have eyeballed the caps as carefully as I can and don't see any obvious leaks so I agree with you. I have carefully cleaned and inspected the boards, but suppose that I could have missed something. One time last night I got something like jail bars (vertical) but not quite that simple (alternating thin and thick lines).

No more 0F/03 errors since trying the Apple 160 pulled from a Centris, but haven't been able to initialize either. As noted in my last post, will try Lido, SF&I and a couple others.

I haven't seen any reference to DiskManager Mac - is this freely available software or retail? This is my first experience with a Mac, I am a daily (work) Windoze user and a Linux hobbyist. Thanks again,

Carl (cseals3)
