No sorry, used all of them and sold most of my complete A+B+C stacks.
Then I had a look 2 or 2.5 years later to buy some more chips and prices were too high to be worth the repair.
We're all hoping for that. But I honestly doubt it will happen soon. See, CPS1 was a hugely popular platform and failure rate is extremely high too. Still nobody seems to be interested in taking up the challenge.
