Honored ContributorHi h,
yes, it is possible but only in case of a windowed ceramic package. Plastic package devices are one-time-programmable. A windowed package device can be erase with help of an ultra-violet (UV) eraser. For more information please check manufacturer device specification (https://www.altera.com/content/dam/altera-www/global/en_us/pdfs/literature/ds/archives/classic.pdf). The following web page can be helpful for better understanding of the situation as well (https://www.elnec.com/en/support/application-notes/html/?file=erasing_eprom). Best regards, Martin Edit: According to the exact device part number format is the package type plastic DIP package. Therefore the answer is no unfortunately. The reason has been already explained.
