So finally installed the video DAC upgrade in my short 520 st with 4 mb st ram and most anders upgrades (blitter, ide, tf030). The video quality was really terrible on this ST. The improvement is huge with this DAC upgrade. Still not perfect but like 90-95%. Also found this old nec monitor which is vga colour compatible.
Loving it..

:bravo: :2k2:

I gave up and discontinued the project a while ago because most people generally ended up making things worse somehow :roll: Just was taking up way to much of my time trying to troubleshoot what people did all the time.

There are still some ST and STE PCBs in the store though. If anyone wants to get one before they are gone.

It’s a big improvement for this small ST.
I would rank the standard ste with the cap mod higher. My Mega ST also has very good video quality.
So probably depends how good your current ST is.

As my small ST was really bad this made all the difference.

My short 520ST also benefited from this upgrade. It's video even had jailbars on an original SC1224. Much better now....I agree not 100% but 90-95% definitely.
