I'd offer you a ROM03, as well, but, I have the same 2 that I've been using for several years, and could use a few extras myself. Maybe I can get you to send them to me for analysis and possible repair.Ok, here's the best part of it (almost forgot):With no cards at all installed, running the stock 65816, you can hear the Disk3.5 coming out of the system speaker! (No, I do not have a microphoneinstalled :-)). All seeks and motor speed changes are emitted. I thought I wasimagining things, but this is for real. After it gets to the desktop, you can hear a rhythmic ticking.It just keeps getting better.... I did say I pulled all the cards from the unit. The one thing I didn't do was pull the Appletalk phonenet adapter out of the rear. When I did that, the unit came to life.Now here's the bizarre part: If I had the adapter plugged into the unit, it hung during boot. EVEN WHEN NOT CONNECTED TO THE NETWORK! I tried four different adapters - same thing. I tried my last Rom3 - same thing.Just when I was convinced I was losing it completely, I pulled the Little-Power and put in a stock GS power supply. It booted immediately and the audio weirdness and instability is gone.Can anyone make sense of this? I'm going to have a beer... Steve
The output filter caps on the stock supply are better than the ones in the Little-Power. -michael NadaNet 3.1 for Apple II parallel computing! Home page: http://home.comcast.net/~mjmahon/ "The wastebasket is our most important design tool--and it's seriously underused."
