* **PSU Option C:** Uses 5v regulation circuit to provide option A or B when not using C64 PSU (which has its own 5V regulation). //I have added this option at the last minute to the PCB as a potential workaround for people unable to get a C64 PSU. People could generate 5v from a single unregulated 9v AC supply (9v AC adapter) or supply separate unregulated 9v AC and unregulated 5v DC supplies (9v and 5v AC adapters), using the same power socket and switch. Please do not assume this idea will work well, it might introduce noise, hum and heat!// | * **PSU Option C:** Uses 5v regulation circuit to provide option A or B when not using C64 PSU (which has its own 5V regulation). //I have added this option at the last minute to the PCB as a potential workaround for people unable to get a C64 PSU.

+ | * **[[wilba_mb_6582_psuopte|PSU Option E:]]** Uses a single 12-15V DC supply (aka a common wall-wart). This is a newer option worked out on the forums to avoid the common pitfalls associated with using a C64 power supply or other AC PSUs. Uses switching regulators (which were not available at a reasonable price or quality when the MB-6582 was designed) in order to generate a 5V rail (or a 5V and a 9V rail in the case of a mixed-SID setup) and a regular linear regulator to generate the 9v rail (or the 12V rail in the case of 6581/ | ||
