The invention relates to automation and computing techniques, in particular, to technical means for studying digital computer structures and algorithms.

The purpose of the invention is to expand the didactic capabilities of the device.

1 shows a block diagram of the device; 2 is a diagram of the element HJ in FIG. 3 — front panel with a removable mask, general view.

The training device contains the address register 1, the decoder 2, the information register 3, the matrix indicator 4, consisting of an array of LEDs with a replaceable mask, switching elements 5 and 6, corresponding to the inputs and outputs of the elements depicted on the interchangeable mask, the information register register 7 and the elements of AND 8, the element of AND 8 consists, for example, of the element 2I – HE 9 and the resistor 1.0 (figure 2).

The device works as follows.

The indicator -4 is superimposed with a mask (Fig. 3) of an opaque material with openings for LEDs and sockets: element 5 and 6 and images of the elements of the studied digital computer.

The learner with the switching conductors assembles the given circuit, electrically connects the sockets of the elements 5 and 6. After that, the initial data is entered into the computer, on the basis of which the recognition of the performed switching is carried out. In this case, the number of the element 8 is entered into registers 1 and 3, a matching signal appears on the corresponding element 6 and the corresponding LED of the indicator 4 lights up. However, due to the short duration of the selection of element 8 and the single selection, this flash is not noticeable on the indicator 4. When this element 6 is connected with some element 5, a unit is written to a certain register bit 7.

Then, the PVM receives information from register 7, after which the rest of the switching is recognized and analyzed by the PU. right. To indicate the state of the modulated elements, the necessary smsdiodes are visibly visible in a noticeable way to the eye, indicating the single state of the corresponding output of the modulo 1 module.

The learner can participate in changing the relationship between the simulated elements, which contributes to the acquisition of practical skills. At the same time, the commutations performed are controlled, which evaluates the accuracy of the student's actions.
