Hi,

Is it possible to add a BOM list to the project? It is difficult to identify the correct SMD packages of ICs and other passive components needed to build it.
Thanks

Entirely my own fault, but after being presented with blank screen I discovered that my intuition about the orientation was wrong (I should have consulted pictures before I started, but I was lulled into a false sense of security by all the instructions and it slipped my mind) :)

Still, it might be nice if it's possible to find a little spot for "This side up" in the next revision.

Also, thanks for doing all this awesome stuff! 👍

I had a round of these made by JLCPCB, with the goal of using them as a 6510 replacement for some new DIY C64 builds, but so far I haven't been able to get them working?

I've tried several known working 6502's - some from AliEx, but others from working 1541 disk drives, but all are failing with similar errors...

The C64 shows a black-screen, and a Deadtest cart won't even work.

I also tried running some tests using a Backbit tester on the MOS 6510 setting, but this is showing failures on:

A=aec
I=peripheral IN
O=peripheral OUT
N=interrupt
W=walking

The only DIY bits that JLCPCB didn't do for me were the jumpers, the pin headers and the machine pin socket, which I hope I've done correctly (see images)...

Appreciate any assistance...
