My programmable calculator (1991): Elektronika MK-52

My first programmable electronic device was an Электроника/Elektronika MK-52 programmable calculator. 

I got it in 1991.

It is a calculator from the MK-61 series, but it has a rewritable ROM. It was very convenient not to have to enter programs by hand.

I also had a БРП/BRP (memory expansion unit), model БРП-4 (BRP-4).

Some ready-made programs were stored in the unit.

You could not write your own programs in it. But you could quickly load these ready-made programs into the calculator and then run them.

With the calculator I learned the practical basics of programming (and they were different from the theory).

Funny thing: the ERROR message can appear during a calculation, but it was read as ЕГГОГ (EGGOG).

Then in 1992, I got an 8-bit Партнер/Partner 01.01 computer (with an i8080 clone). In 1993, a cheap PC-compatible (i8088 clone) 16-bit Поиск/Poisk. In 1994, a 32-bit PC with an AMD 80386SX compatible CPU.
