[6] There are several versions of the machine (Agat-4 to 9), with progressive enhancements to memory, video modes and compatibility with Apple II.

[9] While this permitted some degree of compatibility with the Apple, timing differences between the two CPUs rendered certain tasks (such as floppy disk access and sound generation) incompatible.

Later models incorporated actual MOS 6502 CPUs which permitted a greater degree of interoperability between the two platforms.

The display was provided through a 30 cm SECAM television, rather than a specialised computer monitor, that was connected to the rest of the machine through a 1 metre long cable.

This is reflected in the fact that most of the software available for the Agat is of an educational nature—including a BASIC interpreter, text editing programs, and the "Shkol'nitsa" ("schoolgirl") package, designed to assist teachers in the classroom.

The official selling price for the Agat was 3,900 rubles,[13] as much as twenty times the average monthly salary,[3][14] which put it out of reach of all but the most privileged of private individuals.
