Got my package today! A brand new (in 1991) in box, Soviet RPN programmable calculator MK-61. 105 bytes to enter a program, 4 registers of stack, 15 memory slots for variables. I learned to code on a calculator like this one.

A yellow retail box of the Elektronika MK 61, a Soviet-era programmable calculator, is placed on top of a brown cardboard shipping box from Ukrposhta, the national postal service of Ukraine. The calculator box features an image of the device on the right and Russian text on the left describing its functions.The image shows the contents of a vintage Elektronika MK 61 calculator set laid out on a dark surface. From left to right, the items include:

A blue plastic protective case for the calculator.

The Elektronika MK 61 calculator itself, turned on and displaying green hex digits of a program on its LED screen.

A grey Soviet-style power adapter with a two-prong plug.

A user manual in Russian titled "РУКОВОДСТВО ПО ЭКСПЛУАТАЦИИ" (User Manual) with "МК 61" and "ЭЛЕКТРОНИКА" (Elektronika) on the cover, featuring a circular image of the calculator's keypad design in orange, black, and white.
