Never tried it since I never had one go bad. Maybe because they were not made by MOS but by well known semicondutor makers like SHARP or YAMAHA (*). Also when looking around, I found the version without color RAM easier to find. (*) The part numbers besides the Commodore part numbers gave that away: YM3535 and LH5062B on my 251715-01 and on a 252535-01 SHARP even printed their logo. GerritReceived on 2023-10-16 21:00:16
