@mykrowyre, I've seen this to varying degrees and it has varied for me by screen and connection. Sorry if I've missed it on previous posts but how do you connect e.g. RF modulator, composite, RGB, and to what type of screen?

Yes it is actually, this is a later escom amiga made in france.

I've suspected it may actually be the floppy drive pulling too much current when the stepper starts.

From a quick scan of the boards I don't think anyone has posted about this (sorry if I've missed it).

Kickstart02 is taking place in Nottingham on 29 and 30 June.

Tickets are now on sale.

I realize this is an old post.  I thought I was very familiar with A2000 motherboards, until now. This description appears to describe a motherboard I recently received. A strange looking upside down circuit board to the right of the kickstart rom, socket labelled  HN62402.  If you are looking at the board with the battery at the bottom.

Did you ever figure this out for sure? I did read the previous post.

Please don’t send any monies from the info Snitchy Cunningham has provided.

Send me a PM and I might be able to help you, like any good person in the Amiga Community would 😉
