I can see a number of use cases for that, Rich. I also have a random question: which byte is written first? I ask this because the first byte written will be the one that is latched, and would be in the value range of >00 to >0F. I just wanted to make sure I have the byte data in the right order in my earlier post. . .

In my GPL Code I move just one byte into the Even Address to change a page:

ST   >0A,@>4014

 

Same thing you can do from XB:

CALL LOAD(16404,10) ! Or move >0A at mapper >4014)

 

Assembly has to move a word but GPL and XB do not need to do that.

Your change adds another value to make it a word as it has always been just a byte for me on SAMS.

I have to order some more boards though, as I sold the last one from the first batch just before Christmas. . .I already planned to do that this weekend though, so I will have new boards in-hand in a few weeks.

Here is a photo of the "Grand Prize" drawing from last years TI Fest West, the card was donated by Jim (Ksarul).

I agree, it's a work of art in more ways than one.

Awesome piece of tech, and Rasmus' new Dungeons of Asgard really makes it a must have item!

One down; one to go. It's nice to work on a clean, new PCB as I really needed a break from consoles for a while =]

Just got my bare board last week and I ordered my parts for the SAMS based on the list under the board on ArcadeShopper.  While assembling the board, I notice that the 74LS04 and the 74LS688 have been replaced by 74LS34 and 74LS683.  Can someone explain the difference, please?
