At least one of them was working. We had an Amiga board we made back in the day where the company hired to make the PCB needed a mounting hole and picked a spot without consulting us. The hole would wind up being through-hole plated... and it wound up connecting power to ground. When we got the first batch of 500 boards and went to test it, we got all kinds of cool smoke from the board. We figured out what they did pretty quick and sent them a note on safe places to put their mounting hole.

Oh hell that sounds like a good way to have months wasted by something out of your control...

Fortunately, we got lots of cool smoke to let us know there was a problem, and even more fortunately, we noticed the HUGE EFFING HOLES drilled through the board that weren't part of the specs we sent.

It's exciting stuff! And I was recording on my phone since it's the best camera I've got.

I'm making tons of progress with the new Revision 1 boards, these Aliexpress shells, and the asmx assembler!
The Revision 0 boards were somewhat flaky with resets and booting: the only reliable way to start them was to power on while holding Reset.
Revision 1 starts flawlessly every time. Also the weird distorted text is gone, probably because I stopped trying to save a silly-small amount of cycles by writing words to VDP control instead of longs based on something I read. My woods are tangley, my possums are awesome, and I can play new stuff like Phantom Gear and Curse of Illmore Bay great!
I just need to get down to it and write the menu... and get a mascot!
I can't unconditionally recommend these Ali shells, they seem to fit a bit too tight in my Pal Model 1 MD, either that or I'm inserting them wrong somehow? I'm not used to there being a left notch on my carts. I'm certain I've screwed the halves together tight, and the ill-fitting was there before I'd even used the screws: the clips around the outside edge are definitely strong enough by themselves.

There are two pages I need to write for my website for Revision 1: I've got the blog page which is a mess of events and thoughts as they happened roughly reorganised into topics, and the Technical Report which only includes the final description of the cart, the approaches, the manufacturing files, the firmwares and the compatibility tables.
Are there any topics that you would like to see covered in these pages?
