Household cassette video recorders '' Electronics VM-18 '' and '' Electronics VM-32 ''.
Video television equipment.video playersHousehold cassette video recorders "Electronics VM-18" and "Electronics VM-32" since 1989 and 1991 have been produced by Saratov PO Tantal and Voronezh NPO Elektronika. Videotape recorders Electronics VM-18 and VM-32 differ externally in inscriptions, in VM-18 all inscriptions are in Russian, and in VM-32 in English. The hinged cover of the VM-18 was for the entire length of the device, while the VM-32 only hid the Russian-language part of the keyboard. Inside: the video and color channel corresponds to the VM `` Electronics VM-12 '' and is made on 1005 series microcircuits. The only difference is in the introduced clarity regulator, in the VM "VM-12" it was determined by the factory settings. The radio channel of the VM corresponds to the television one. The CAP block is made on the 1043 series since the motor was applied brushless. The fundamental difference from the VM-12 (except for the front loading) is in the use instead of one LSI for the VM-12, a control unit made on a KR1820BE1 microcontroller, with a corresponding strapping from a heap of microcircuits (561, 1561, 573RF and 537RU) that expanded the service, gave a remote control, but also ruined everything that was conceived. The circuit consumed a lot of power, heating led to a severe thermal regime of the elements, which, with the quality of the components available at that time, did not contribute to reliability. VM '' VM-32 '' is interesting as one of the last domestic serial VMs, made on the domestic element base.
