A rare green not frog named 41W1024!

[xiphmont]

I've modded nearly 300 X61 inverters to drive LEDs over the past four years, and I thought I'd seen all the possible FRUs. NOPE.

Not listed in the hardware reference or parts cross-reference: the Sumida FRU 41W1024. Undeniably an X61 inverter.

And here it is, before modification, for reference purposes.
