I have an AGC AC1100-12 'TURBO BOARD' board that I've been tinkering on here and there, trying to get it working. It's CPU is a Sony CXQ70108D-8 which I understand is a V20 and I feel that it's original to the board. If the -8 on the CPU indicates 8 MHz then this would be a 50% overclocking. If this is an 8MHz rated CPU then... was such aggressive factory overclocking a thing? I think I'll pull the CPU and test it in a less intense environment.
