For the serious collector: the rare Micro-Professor MPF-1 Plus. While the standard MPF-1 featured a hexadecimal keyboard, this 'Plus' version is equipped with a full QWERTY keyboard and a 20-digit LCD display for text. ​This model is significantly rarer on the market and offers expanded programming capabilities. It is also housed in the famous Multitech 'book case'. A true centerpiece for retro-computing enthusiasts.
