Description
Replacement for the 7811 Mask ROM CPU found in the Juno 106. There are two unique Mask ROM CPUs in the Juno 106, one on the main processor board (D7811G 101) and another on the module/voice board (D7811G 102). These chips are not interchangeable, so be sure to select the correct kit from the dropdown menu on this page.
This kit includes a genuine NOS 7810 processor and additional EPROM with the firmware code found on the original 7811. The board will require modification to reference the external ROM. This is an intermediate level repair job that requires skill desoldering to avoid damaging the fine traces on the board. If you would like to send your board in to have me install the CPU kit, please contact me through the menu at the top of the page.
