A new release of the MultiCart PCB
Hey Folks, I've done a respin of the Multicart to make it more compact, and by using an evil hack, I've even made it so you can remove the ROM without needing to desolder. IMG20230410150432.jpg This is the new V2 release of the Multicart. Now small enough to fit inside a standard CreatiVision shell....

Re: Black Screen CreatiVision
Haven't given up, not by a long shot. If I have to I'll see about rebuilding that circuit to test out of the board. Whatever is going on there, it's not happy. Actually, has anyone got a 700305 model (Early PAL with RF box on a riser) that can take a hi res photo of the top right corner? This is the...

Also Mono, so we don't get to hear the dulcet tones of Dick Smith

Re: Black Screen CreatiVision
That circuit around the clock is a mess! Currently both pin 39 and 40 of the TMS are being held high and I can see no oscillation of the crystal. The clock circuit winds through a different part of the circuit, and, of course, there's no silkscreen so I'm having to trace over both halves of the boar...

Re: Black Screen CreatiVision
Solder joints are dull, and I think this may have been a "friday afternoon special". Most of the vias wren't flowed all the way through, and the same applied to many of the legs of components. There was pits and cavities in many of the solder blobs too. No obvious other hints of corrosion. I've sinc...

Re: Black Screen CreatiVision
OK it looks like there are some significant degredation of the vias on this board. I've been bodging and fixing all day.
Fixed three address lines and two data lines and now I have activity all over the place. Still no picture though.

Black Screen CreatiVision
So I've been working on my CreatiVision. So I have fixed Phi by finding a trace broken. Similar on the NMI (Which wasn't being pulled up) traced to a bad via. I've also fixed the trace I broke. (Whoops!) Now I'm stuck with all Address lines pulled high, and all but D0 pulled high on Data. Phi in and...
