The interface "Transtape" is one of the most popular transfer interfaces in Spain. There are three versions of this interface: Transtape 1, Transtape 2 y Transtape 3.

   All versions have the same electronic scheme. Hard Micro was updating the EPROM to have more functionalities over time.

   The Transtape 1 and Transtape 2 have the same exterior and interior design. The only difference between both models are in the EPROM routines because Transtape 2 includes more options than version 1.

    Two versions of Transtape 3 are known:

   The first version use the same plastic box as Transtape 1 y 2. The board was redesigned, leading to a different button placement to previous versions. The NMI button is red instead of green and the switch "Turbo- Normal "is now called "Cinta-Menu".

   The Second version of Transtape 3 come in a different and bigger plastic box than forced to redesign the board again. The button placement is just like the other version of Transtape 3. The NMI button is red and the box has printed "Transtape 3".
