It looks ok..

Could you try the RAM boards on a known working ST ?

Also I didn't see you mention the shifter before, was getting hot ?

I tested it on my spare Mega board before I put it in the STF.

I've also tried a market btw, with the same result.

Shifter doesn't get hot atm, think I had a dodgy one before as this is a different one.

The RAM board shouldn't make any odds.. nothing has changed other over the STFM in that respect, other than the falcon ram board, which is basically the same as my 4MB simm kits which fit the STFM,

I guess if you patch the video cable you should really be at the same point as Icky...

That's the bit I can't understand right now.

I'm going to take all chips and the ram out and test them back in the Mega before going any further.

Probably a good idea.. Also check no bent pins on any chips or sockets.

Ok, so I like to be different.

No cool flame effects though

What did you do to get it "working" ?

You must be at same point as Icky now in any case...

Took all the chips out of my good "Mega4" and put them into the STF. Connected up the marpet (think your board should be ok too, just wanted to leave it alive :D )

And finally, the Rom socket pin for /OE Was bent where I'd pushed it too hard with the scope probes.

Still gutted I got no bombs demo. Might have to code my own when it's working.

I will send you a diagrom chip in the morning when i post ickys... 2 machines with the same fault means something else is wrong in the design.. we need to check RAM is working.. I have a feeling its not, but no idea why.
