I don't recall ever seeing an option ROM for the m100 that didn't have the flex circuit wrap around over the chip.

There are several forms of rom pinout adapter for M100. The "Guardian" like Ultimate Rom II has is just one. (the wrap-around thing you're talking about)

Aside from that, there are also simple PCB's with a DIP chip soldered on, PCB's with a SOIC chip soldered on, and the EME ROMBO (an upside-down U shaped interposer that fits down over the top of the chip), and there were 2 roms sold by Radio Shack that came on custom PDIP chips installed right on the carrier with no pinout adapter needed. (Multiplan and Interactive Solutions).

I know I'm curious, but not $50 curious.

    Never seen this before.  Does anyone recall a product called "ROM
    POWER" for either M100 or T200?

    I don't actually think this is for M100...
