                Turbo mode DRIVE


  For those who have not yet gathered the device, today I bring 
him the most common scheme. Integrated circuits (series 555, 
1533) are soldered on top available computer power output (7 
and 14 feet). The remaining connections are mounting wire. 
On-board computer must be cut track, running at 24 feet VG93. 
Legend items are for computer ZX Scorpion-256. 

  That's it. This revision will not only increase speed of 
loading programs from the drive, but and significantly reduce 
its noise.
