Re: TT issues. Help welcome...

ok, a few developments. i figured if i was going to make any headway, i would need a control machine. so i sourced an Atari-VGA monochrome cable and fired up the MSTE. the Epson SMD-380 that was on the MSTE is working but is 720k, not 1.44mb... so my MSTE is a 720k version. i don´t know how i was so...

Re: MegaST to be restored

never tried to run it. considering the amount of dirt and corrosion, i wouldn´t feel safe in doing it before checking critical parts.

Re: TT issues. Help welcome...

the drive lights up on boot and when trying to access the drive.

i will remove covers and see how the parts move. maybe even make a vídeo and upload to YT.

replaced the TT floppy cable with the MSTE and no difference.
