|So far there are 3 revisions of the cpu adapter included with the Spectra upgrade, Rev A,B,C,|
Rev C looks most promising
Rev C Supports Cpu voltages 2.0v, 2.2v, 2.4v.
Rev. A & B supports 1.8V, 2.2v, and 2.4v, *2.8v and *2.9v on rev B only)
Clock multipliers 2.5, 3, 3.5, 4, 4.5, 5, 5.5 and 6^. (^Can you say 400mhz?)
Bus speed appears to be set at 66 mhz (Darn).
Maybe those K6-3 333 AFK's and 1 K6-3 400 I have will work with these? Takes all the strain of the i-Openers Cpu power supply V-reg.
*This adapter requires an external +5v and +12v thru a floppy drive style power connector.
