Yes, finally one has come up.

I have three sets of Life Force PCBs, one has been spoken for locally, and I have just finished a second set and playtested on my bench. (A third is available as a fixer-upper as it looks like it's a little out of my league)

So, I am looking for $275 shipped to the lower 48 for a working Life Force PCB stack. ***THIS BOARD IS SOLD***

Also have a third stack which as I noted has a few issues that need to be fixed:

- board is missing sync output. (Not sure where this problem is coming from, except knowing it's a top board issue, and there's a bunch of Fujitsu TTLs all over the board)
- there is an issue in VRAM on the bottom board (I know this as this bottom board paired with a good top board runs with jailbars through sprites and text, and shows jailbars through the VRAM part of the self test display)

Looking to get $150 shipped in the lower 48 for this fixer-upper PCB stack.

Just a side note. These boards have fragile 4416 video RAM as I learned the hard way last night, doing final test on the second good set I sold earlier. Board had textbook jailbars in the sprite layer similar to what I see on my third fixer upper set. Ruled out the TTLs between the RAMs and the edge connector, so its another case of the video RAM blues.

Bumping, I have one Life Force PCB stack left, it is non-working:

- sync signal not working
- board intermittently resets
- video RAM issue

I don't have the time to figure this board out; I have dozens more boards less complicated to get to.

For someone with more time/talent/dedication I will sell the board for $100 shipped (in the lower 48). As a bonus I will throw in 6 NOS video RAMs of the type used on this board.
 
Interested in the non-working PCB. Already sent a PM.

Edit: I'm still interested if you are willing to sell.
