try one of these, it all depends on the monitor / it's settings and how BIG you want the picture as to how good your picture will be http://www.ebay.co.uk/itm/Atari-520-1040-ST-STE-high-resolution-monitor-VGA-cable-adaptor-cubase-Notator-/150664984279?pt=UK_VideoGames_VideoGameAccessories_VideoGameA...

Re: STE no sound BUT press reset and sound appears!

looking at this board again today

if it has 512k or 1mb memory no sound on initial start (ok on reset press)

with 4mb memory there is sound as soon as machine boots

i guess due to the extended boot delay

can anyone point to a reset schematic link?

thanks
