I'm having problems locating data on:

Texas Instruments: T712 (4 pin surface mounted SOIC I think)
Toshiba: TA7259 3Ph motor driver.

These are components found in the laser scanning module from a SUN
Microsystems SPARCprinter. The asssembly is similar in construction to that
found in the LaserJet series of printer (well at least the III anyway)

I'm trying to reverse-engineer the circuit, so I can use the module to
project a vertical line onto an object, to implement a primitive 3D
scanner...

Many thanks for any info leading to the successfull capture of said culprits


Dave.
