It has recently come to my attention that the NCR 52801 is a drop-in replacement for the Motorola MCM2801 and thus it can be programmed in the 2801Prog programmer. I have thoroughly tested the 2801Prog with the NCR 52801 and have verified that it works. More more information see the 2801Prog product page here. The programmer is available for sale on eBay here.
