I released the v1.501 as web update.

Just use the Help/ Check for updates function to get it.

New modules since v1.50:
Lumo *.MESH Load

I've written a thousand times that it doesn't work and what the problem is with the Sk A1200.

 I repeat:
I was doing some tests by restarting the A1200 several times, and at a certain point, while it was restarting (I was busy with something else), I noticed a faint burning smell with no smoke and a black screen....
I quickly turned it off.
Once restarted, the A1200 displays a yellow screen and the power LED flashes 9 times, then a black screen and restarts.

Suspected so. Thanks.
Might have a go at cleaning it up if I get time otherwise will sell for spares.

And what exactly happens after you change that line?

In hostname ?

changes the name of your system in network settings. Minor irritation that my A1200ng was called A600gs on my network 

Picture attached shows A1200ng on my router as A1200ng

Thanks for that. I did a bit more digging online and I think you're right.
I've opened up the unit and taken out the PSU/Drive assembly and I do suspect it's the battery that's the issue.
The battery itself doesn't look too bad on first inspection but I think I can see corrosion on the board - the dark stuff around the battery.
Am I right in understanding that is corrosion? Did you see that on yours?

Also the CPU switcher I mentioned is actually a ROM switcher.
I have found the 68030 that I was thinking about and it was for an old Amiga 500 that I sold many years ago. For some reason I kept the 68030 - a mega midget racer. Still have the manual as well 

Thanks again.
