Adapters to replace MPS-6550 RAM chips in the Commodore PET 2001 are finally here!
I have been selling adapter to replace the MPS-6540 ROMs in the Commodore PET-2001 since 2009, but until now, there has not been a solution for the equally scarce MPS-6550 RAM chips. This product finally solves this problem once and for all by making a simple way to replace a 6550 RAM chip with a common 2114 RAM chip! Order here.
