Can't be! The 9830 tape drive and cassette are very different to those 
used in the 9825. The 9825, as we all know by now, uses a tape driven by 
an endless belt in the cartridge. The 9830 uses tapes with the same form 
factor as audio compact cassettes. The 9830 tape drive has 2 motors which 
drive the 2 spools, with a pair of solenoids to engage the drive. There 
is no capstan or pinch roller.
