Ok, so I would carry out the floppy mods that exxos has suggested. Have you recapped the psu yet? It could be power related.
But another cause of floppy failure is the DMA chip, I had similar in one of my Mega STs and replacing the DMA cured it.
Can all registered uses please login, even just for a few minutes..
It helps build a picture where our "good traffic" is coming from..
Thanks :)

Re: TOS error #35.
I have an eXxos PSU of the first version released. The original Mega ST PSU apparently works fine on another computer.PhilC wrote: Thu Nov 07, 2019 5:56 pm Ok, so I would carry out the floppy mods that exxos has suggested. Have you recapped the psu yet? It could be power related.

I will have to try those eXxos mods, but I am not an electronics technician, I will take it to a person who welds reliably.
Thanks for answering.

I have an STfm for parts, if the DMA chip is the same I can try replacing it.

Re: TOS error #35.
Well, I haven't had much luck with my exploded STfm: it has all the chips soldered on the motherboard, except the TOS and another one that I suppose will be the shifter.
I can't test the chip DMA on my defective Mega ST.
