Cool. How do they look?

I think it looks nice. The deep green 4-layer PCB will fit perfect into the Falcon.

The back side with the assembled parts from the factory


The front side that will require hand soldering and tests


EDIT: I have just noticed the JTAG labels are not properly aligned.

The Power Core 030 assembled last week with both CPU versions! :) (thanks gerald)

Full board:

Good job! I certainly don't envy you having to solder that QFP 030. :)

Thank you. I got the help of a friend for that. Now, the CPLD is programmed. ;)

Hi TotO, how did you get on with your board, did it perform as expected?
What was the rationale with removing FPU from the board? Or does it somehow use the original Falcon fpu?
An observation is that this has moved the (DFB1) design towards being able to use a 68040? (with reclaiming the FPU space) :D
Were you planning a Power Core 040? :lol:

His rationale behind the project is quite the opposite (explained in his first post) He wanted to make it closer to a stock falcon, but what a falcon 'could' have been at launch, ie; 32mhz 030 and 16mb ram.

What i struggled with was removing the FPU on the board, but i realised there was a post to say the internal FPU should be usable with an extra soldered wire. @Tot0 did it all work without an issue?
