Progress in DVD burners

After ten years of service, the DVD burner in Trusty Desktop stopped playing.  Something got jammed and the tray would no longer open.  Even after pulling the drive from Trusty Desktop and prying it open, I could not get to tray to move, at least not with the amount of force I dared apply. 
  So ho, for a new one.  A bit of internet research disclosed that the design of DVD burners changed a year after Trusty Desktop left the factory.  The DVD burner that came with him has an IDE connector, a parallel interface with 40 odd pins in the connector.  The new DVD burners have a serial interface (only four wires).  They haven't made the DVD burner that fit Trusty Desktop for the last ten years. 
  OK, so there is a salvation.  They now make USB DVD burners, USB is universal, Trusty Desktop has plenty of USB ports.  So I bought a Verbatim model down at Staples, only $50.  Very small, only 1/2 inch high, compared to old one and 1 1/2 inches high.  It's faster too.  Burns a 4.7 Gig DVD in about half the time the only one needed.
