You know you wanted to use the pink in the first place :D

Looks good RJ and know what you mean with the 0.3 bit.

@rubber_jonnie thanks for posting the how to, I've used it to build myself a PSU for my STM.

So now all I need to do is fix it,. Booted to white border and black foreground, ie memory.

Awesome, glad it was good for somebody else :) Have you 3d Printed a case? If so how did it turn out?

As for the black screen/white border, if you can use a diag cart you may get an idea of where the problem is (Mine had an ageing piggy back upgrade). In the end mine was fixed, then it failed, so I fed it one of exxos' 4MB MMU/Shifter upgrades after removing all the RAM. Works just lovely now :)

@rubber_jonnie actually I lucked out. I removed the glue and mmu which were already nice and clean but someone had bent a couple of the pins.

And whilst I was at it I threw in 6 new tos roms and were up and running with tos1.04 now :D
