Low cost DRO innerds

Has anyone taken apart one of those low cost single axis 6"-12"-18" etc
DROs sold all the time on eBay ?

Specifically, is there a point where the raw quadrature is "extractable" ?

I probably could do what I need via the SPC port, but that would mean decoding
the SPC output .. being lazy, I'd rather do it the "traditional" way.
