M 16-22
It was manufactured from 1987 to 1988 by ZVT Námestovo. The computer was inspired by or was successor to SM 50/50. Hardware is based on Am2900.Operating systems running on the computer: TMOS-2.1,TMOS 3,FOBOS 3,DOS-RV 3,SYRPOS 3,DIAMS 3,DEMOS.
The M 16-22 is a member of the SMEP family of 16-bit minicomputers. The architecture and system features were determined using the new M 1622 processor, using a common bus as the system interface. Mechanically, the system is solved in the SMEP stand.
The M 16-22 system is in the following configuration:
- processor controller and peripheral device controller
- display workplace
- mosaic printer CM 6303 with parallel interface
- cassette disk memory CM 5410 or CM 5400
- magnetic tape memory CM 5302 or CM 5303
The M 16-22 system is designed for solving multitasking applications, real-time control, creating computer networks and for solving scientific and technical calculations. The block diagram of the system is shown in Figure 1. It shows the modules used in the system and their connection to the relevant bus. Modules that are built into the processor grid are delimited by dashed lines. Devices built into the rack are separated from other devices by a dotted line. Expansion device blocks are dashed.
- SM 0260 core processor (4x Am2901/K1804VS1)
- SM 0262 core processor with memory organizer (MMU)
- SM 0263 mapper and ECS (documentation not available)
- SM 0264 Floating point processor (16x Am2901/K1804VS1)
The minimum functional configuration is SM 0260 and SM 0262.

peripherals used from SM 4-20
The combined module is 2/3 SMEP board. Three subsystems characteristic of SMEP series computers are combined on it:
- loading module
- asynchronous adapter
- simple timer
Each of these subsystems works independently of the others. On the board there are resistance dividers for the lines of the common bus, for this reason the board in the system is located at the beginning of the common bus.
The bootloader subsystem enables:
- emulation of the programmer panel (reading or writing to the selected address, starting the program from the set address, listing the contents of the processor registers R9, R4, R6, R7, loading boot blocks from external memory into the operating memory),
- diagnosis of the central processing unit and operating memory,
- loading boot blocks from external memory devices into the operating memory and then starting the program from address 0 of the operating memory.
The mentioned functions can be selected or suppressed by setting the corresponding jumpers on the board of the combined module. These functions are provided programmatically, the program being stored in ROM memories.
