=== CPU === The basic setup of all F256 is the [https://westerndesigncenter.com/ Western Design Center] '''65C02''', a slightly enhanced CMOS version of the very popular 6502 CPUs. The main difference to the 6502 in the 1970s and 1980s is the faster clock speed and the lower power consumption. The 65C02 can also be replaced with a [[Template:Main2/65816_Processor|65816]] as a drop in replacement. '''Note, however, that while the 65c02 includes the additional Rockwell instructions (BBS/BBR, RMB/SMB), the 65816 does NOT. Therefore, these instructions should be avoided to ensure compatibility with F256 machines using the 65816.''' In the F256, the CPU is always clocked at 6,29 MHz (6,293,750 Hz to be exact, derived from 25.175 MHz / 4 as discussed on [https://discord.com/channels/691915291721990194/1054250056703815680/1177306520925524018 Discord]).
