Hello together, I did some try out on overclocking the 80C85 in my M100. I was quite successful using an oszilator with 7,3728MHz which gives a CPU clock 50% higher than the original one. My M100 run with this w/o any issues in running BASIC so far, gain in performance is visible and amazing. But there is one thing you might have an solution or even idea how to solve for. TELCOM and any program communicating via serial port are not working as PIO 81C55 gets the clock from CPU which is now 50% above the original value. Any comment from you is welcome
Kind regards Georg Käter
