Some time ago I posted on here asking for troubleshooting tips,
because I've got a few tatty Beebs that only power up to a continuous
tone. I got a reply pointing to a really useful document containing
descriptions of what could cause this.

I lost the link and can't find it despite much searching. Can anyone
shed any light on this?

The only Beeb I fixed was the one with the scrolling fault, using info
from the service manual. One of the others gave the startup screen
after 30 minutes of being left on, then immediately crashed.
