Awesome. PM sent!
If I have responded to your pm before this post them your order is shipping today (if paid).
Starting now I will take orders but they will not ship until the sockets I ordered arrive later this week or if you only want the module.

I just had a thought - this will (obviously?) only work on the dash board with a 12mhz processor right? Since you are then just underclocking it by 2mhz.
If it has the 10mhz 68k (do any dash's have this?) then overclocking by 2mhz might be an issue?

"dash" means 12MHz... so if your board has a 10MHz chip and a dash sticker, then the sticker is fake.

Would this work on a long board with 10mhz clock then?
the boards can handle 12mhz, ive tried it on a mercs short board and it ran fine for several hours. its less than a 10% overclock so its not really wild.
edit: i didnt try the dual crystal mod on the mercs bord, i physically soldered a 12mhz crystal on it. i dont know if the dual crystal mod works with a 10mhz board but i would think it just switches from crystal to crystal so physically it should

It has already been tested, zero issues that could be noted.
Yes, it should.
Correct, the correct crystal is used based on the game, of course, you can change it to use the crystal you want as well.
The difference between a 10mhz pcb and 12mhz is the crystal. This mod has both crystals on it. The multi tells the module which crystal to use for each game. Therefore it should never crash.

Ahhh - I thought (for some reason) that the motorola 68k was either rated for 10 or 12 mhz.
technically yes the last 2 digits of the 68K specify the target clock speed. but as has been mentioned many times before ad-nauseam there are no ill-effects from overclocking with a higher speed crystal. In-fact there is evidence of Capcom installing "-10" 68Ks on mobos with 12MHz crystals.
I beg of everyone in this thread to not beat this dead-horse any further
This has been discussed to death 5x times over already.
if you want to know what speed your A-Board is currently read this thread:

If you want to relive the thrilling debates around 10MHz vs 12MHz and everyone's opinions and contribute more opinions then go here: https://www.arcade-projects.com/thr...rystal-oscillator-to-upgrade-an-a-board.5721/
lets not devolve this thread in to repeating all of the same questions and arguments and speculation that seems to happen every time this topic comes up.

Got it! I didn't mean to start a firestorm that has already happened!

are the cables being used are the same Adafruit 1.2mm flexible coax?
