Good day,% habrauser%.
In my second habratopica, I would like to talk about the Soviet microcomputer BK 0010-01 and my unsuccessful attempt to get it started.
Details under the cut (carefully, many images - 4.4 Mb) A bit of information about the hardware. According to the official documentation for the BC (Home Computer) 0010-01, it has the following characteristics: Speed - At least 0.3 million short operations per second. The capacity of random access memory (RAM) is 32 kB. The capacity of the internal UIV ROM is 32 kB. Speed exchange information with a cassette recorder - 1200 Baud The capacity of an external read-only memory (ROM) in the side of the MSTD -
16 kB The
number of keyboard keys - 74 pcs.
The capacity of the drive on a MK-60 type compact cassette is no more than 0.5 MB.
In September 1989 it cost 750 rubles, but I got it for 90 :) Of course, it’s not in such perfect condition as it looks in the title, but in such On on the back cover you can see a metal plate with a brief information about the device: There are 6 connectors on the back side. From left to right, in order: BP - a socket for connecting a power supply unit UP - a plug for connecting external devices programmatically controlled by a PC DTV - a socket for connecting an RGB video input of a TV color image TV
- socket for connecting to the video input of the TV in black and white
MPI image - plug for connecting the MSTD
MG unit - socket for connecting the tape recorder
Having unscrewed a couple of bolts, our eyes open a hefty board with two loops to the keyboard Speaking of the insides. In computers you can find a lot of precious metals. Paper cut: Gold - 0.7141 grams Silver - 3.2997 grams Platinum - 0.0060 grams Palladium - 0.0350 grams Ruthenium - 0.0105 grams
After flipping through the documentation and carefully examining the "guts" of the CD, a natural desire arose to start the whole thing. In order to display the image, you can use two options: DTV and TV sockets. A TV was chosen, since the wiring of this cable looked the simplest and most understandable for its implementation. The power cable also did not look particularly difficult, judging by the power supply unit on the BC, you need to supply 5 volts and 1.5 amperes. Since there was no suitable rectifier at hand, I decided to take the adapter from the laptop. At the output, he had 12V and 3A. An excellent way out of the situation was made from improvised means: One, of course, it was not clear: Where is the land? The issue was quickly resolved by inspecting the port for power from the inside:
In obedience to intuition that the “fattest” path by tradition is the earth, we boldly solder the earth to the second port. I want to note that everything was done in order to only start, so it was not done very carefully ... Speaking of accuracy, L7805 from this the current was very hot, and since there was no suitable radiator (10x10cm) on hand, I had to install active cooling :) After all the checks, the launch still took place. But to my great disappointment, there was not a single image on any frequency. Perhaps the BC itself is not in order, but I really want to believe that this is not so and the whole thing is in my crooked hands. After the advice of good comrades in the comments, I connected the BC to the VIDEO connector. It worked, though it works for 1-2 seconds, and then it is cut down ... I'm afraid that L7805

From the power supply, the BC has earned fame. Even played a little with her :) Here is a photo Links: Link to the documentation for BC 0010 (0010-01) Wikipedia BC , you can find a lot of useful information and links to interesting resources dedicated to BC Memories of BC 0010 - A very useful resource, a large number of articles about BC, scans from magazines and much more
