happened across a pair of these due to a friends dibs on a bankruptcy sale for silly money 
a fairly impressive bit of engineering ; just wish they made these things out of more metal 
has the most useable scratching capability ive encountered so far; then again, given the resolution of the scratch tracker encoder, the reason why can be seen
almost perfect, only i wish that they would include mp3 play off memory card/usb device in the future.. and possibly option a platter that actually rotates (you get used to it tho).
Chip details:
(DSP) ti - tms160 320da150pge
(PLA) xilinx - spartan - xc3s50
(RAM) samsung k4s281632i-uc75
(? - dolby wtf) dts dspd56567ag150
65.9 mhz crystal
(? - ic) 6417709S / sh3 / 133v
(? - ic) panasonic nm103s71f
the suspension system
pitch/nudge tracking
correction, adjustable mechanical platter friction !
general tracking also done by the scratch tracker; depending on the state of the pressure sensitive platter ribbons status.
scratch table mechanism, note the pressure sensitive, multi contact ribbon.
scratch tracking mechanism.
ha! jrc 4580 - as output stage (hmm as seen in berry stuff)
one scarily big switch mode psu for this ..hmm !
