I still need to confirm few things but can do that later today. I think it was a combination of several faulty elements at the end. As I mentioned running with a DIP cpu at the moment. I'd like to see if both my plcc cpus are bad or not. Also ram and TOS. I've been through the board few times forward and back and couldn't find any bad solder or trace, reflowed it twice so I was really scratching my head.

I have a nice custom case idea for this.

Congrats on your efforts! Another member of the H4 club. :dualthumbup: :dualthumbup: :dualthumbup:

Thanks.

Got the HXC working. Blitter and mid res also good.
There's still much to be done. I'd like to install the 1.44MB upgrade, DMA fix board is on the way. IDE to be finished. But also check various tos options.
I have a micro gotek that 's for the case mod at the end. It's a nice project overall.
