I see the Micromac website is still being hosted, with these accelerators still listed for sale. Anyone know if they're really still selling old stock?

Also, can someone familiar with the MT version of the Soeedy accelerator (for mac iisi, iifx, quadra 700/950) tell me the frequency range provided? The webpage says over 50mhz for the iifx, which means at least 100mhz oscillator, but need to know how much higher it can go.
