Disclaimer: Since switching the role of MPU cards involves exchanging two or three EPROM chips and one SRAM chip, we assume potential buyer is familiar with the procedure of replacing IC correctly. The buyer should be responsible for any damage to his/her tape recorder if common practice is not strictly followed. Our card will be shipped as a master MPU (1.820.786.33). We suggest you start the test by removing your own master MPU 1.820.786.XX and replace it with our card. Your A820 should boot as a A820 MK-II - 02/93, as shown in the last picture.
