TimC Posted September 7, 2022 Share Posted September 7, 2022 Just curious if anyone knows what this mod is for. I purchased this unit cheap on eBay and it works. However, not sure what this mess of wires and components are for a Rev B board. I have a Rev E also without these mods and I have seen a picture of another Rev B without all this. Just to point out ones in particular, there are resistors across 2 of the RAM chips. I am thinking the other wires are for an sVideo mod or something?

MasterMotorola Posted September 8, 2022 Share Posted September 8, 2022 This looks like the John Russell Innovations ST4096C upgrade to give the ST a 4096 colour palette. Below is a photo of the same upgrade on another machine found online (plus a Tweety board and JATO 16MHz)... Quote Link to comment Share on other sites More sharing options...
TimC Posted September 8, 2022 Author Share Posted September 8, 2022 Hmm, interesting. Is there a good way to test this? Which software package supports this mode? Quote Link to comment Share on other sites More sharing options...

TEST.PI1 Open this attached PI1 with neochrome. The palette is a STE gradient of black to white (16 color). But is there 2 shifters or only one ? This mod requires to have 2 shifters, as you can see on the picture posted by @MasterMotorola Quote Link to comment Share on other sites More sharing options...
