Subject: Re: RD53 Disk Not Rotating
Just in case anyone is interested, replacing the failed Darlington
transistor fixed the problem. The RD53 now spins the disk again. Thanks
to everyone who helped.
Some people enjoy repairing things. I find it a bit of a drudge.
What I enjoy is the feeling of satisfaction when a repair succeeds :-)
Well done to all involved.
I am now looking with renewed interest at my pile of doorstops which once
spun.
Regards,
Peter Coghlan.
When, like me, you don't know a lot about electronics beyond some
theoretical study as a student many years ago, it is especially satisfying
to make a repair like this.
With regard to your doorstops, if they are RD5x disks then I would be more
than happy to take them off your hands :-) Alternatively, I can share what
little I know about getting them working again (mainly RD53).
Regards
Rob
