Today I would like to introduce the respected audience of Hiktaims with another exhibit of my modest collection of ancient technology.



So, in front of me is a large cardboard box with the words “Apogei BK-01 personal electronic computer”. Let's take a look inside.

(Attention! There are a lot of pictures under the cut).

Unpacking

1. Original box

The box contained the following artifacts:


2. Another cardboard box

Opening the boxes recursively, we retrieve the unit directly (the first picture in the post)


3. Box with power supply


4. Power supply




5. Manuals


6. Cassette software






7. Different adapters and cables

Specifications

Apogee BK-01 is a version of the legendary computer Radio 86-RK, somewhat improved. The classic Radio 86-RK had 16K of RAM, with the possibility of expansion to 32K. At Apogee, the amount of RAM is 56.25K.
Subsequently, a version with a color image was released, Apogee BK-01Ts (but I just have BK-01).
I got a copy released in April 1991.

Turning on

In order to start the computer and load any program into it, we will need a TV and a tape recorder. I used a relatively modern TV, LCD 15 ", and a small hitch came out with a tape recorder. The fact is that I have not had any tapes or devices capable of playing recordings on them for a long time.
Therefore, a wonderful device, a monaural voice recorder Marantz PMD222, was purchased for avito.



Marantz PMD222

Also had to solder the adapter to the tape recorder and TV.

So, the entire system assembly looks like this:



Include:



Download the game "Tetris", the first on the cassette with games. To do this, enter the command "I" and start playing the tape. When recording with the program is over, the following will appear on the screen:



These numbers indicate the starting address of the program, the size and the checksum. To run the program, enter the command G 0000.

The game starts:





And finally, the video gameplay:


During the game, it turned out an unpleasant feature: the image synchronization periodically fails. How to fix it, I do not know yet.

Documentation and useful links

I scanned a piece of documentation that was bundled with a computer, in case anyone would be interested.

Electrical schematic diagram

Manual

I did not scan the “Appendix 1” to the Operation Manual, which contains a reference book on the K580BM80A processor command system and other information necessary for programming in assembler. However, you can find this book and other documentation for Apogee by reference .

I also wanted to take photos of the board, but the factory seals remained on the case, I did not open them. Good photo boards for the "color" version can be found here .

That's all for now.
