Analog transistor computer

The basic member of the MED-T kit is a transistor computer Meda 40 Ta, which in the standard assembly contains a computer unit for solving linear and non-linear differential equations up to 12. For school and teaching purposes, the study computer is determined by the 20 TS, derived from the computer 40 by reducing the number of computer modular units. In order to solve complex tasks, several computers can be combined in parallel with a medal 40 TA, or it is to expand the computer's computing capacity Meda 40 The 40 TB medal. Combining computers Meda 40 Ta and Meda 40 TB creates an analog middle -size computer of 80 t to solve demanding differential equations within 24 order. Connecting a computer Meda 20 TS with a computer 40 TB of a computer is a medal 60 t, which is a simpler variant of the middle computer Meda 80 T.
