Mac wont start up, no mouse or keyb response

[bbcmicro]

I left my Mac Classic on for a while, but forgot about it. Coming back,
the mouse wasn't responding. Nor was the keyboard.
Restarting had no effect, the happy mac would come up, but the system
would hang at the "Welcome to Macintosh" screen. While loading, the
mouse couldn't be moved.

I couldn't boot from ROM, no keyb! I used a system disk, which booted
but I still couldn't use my mouse or keyb. When I booted again, it hung
at the welcome screen.

And there it stayed.

Im running 6.08

Whats the problem?

How long was it on?

bout 4 hours?
I suspect a blown ADB fuse, but wether its on the keyboard or in the mac is a different, and fundamental, matter.

Also I dont much fancy component-level soldering. Never have been any good at it. Or soldering in general. Shaky hands!

Now I have a good reason not to leave my mac classic on for too long. If you are in need of replacement parts for your classic, I think Vlad has one that has a busted CRT he's parting out.
