Today I got my (first) Soviet ZX Spectrum clone. The person who sold it to me had inherited it and had no idea how it worked.
It seems to be a home-made clone, rather than a factory-built one. See picture in case I'm wrong about this:
I have looked at the most similar ones I could find online, but the ports seem to be in an unpredictable order on different clones. I show them upside down here to match the subsequent picture from the inside of the machine. I take it the port with the (in fact upside down) T is the electricity adapter socket, but would value confirmation of this before I fry the computer by plugging the electricity adapter (which I have) into the wrong place.
Here is a picture of the ports as they are connected to the motherboard. As in the previous picture, the reset button is on the far right.
And here are the ports up close from the inside. Again, I'm guessing the two thicker wires connected to the port next to the reset button confirm that it is the electricity adapter.
So my question is - can anyone with more knowledge of Spectrum (clone) architecture and/or electronics confirm that the port next to the reset button is the electricity adapter, and divine what the other ones are? For practical purposes, the monitor / TV out and EAR would be the most useful ones, though I take it these Soviet clones often had things like joystick ports, and I got a five-pin joystick together with this purchase.
I should say that all the cables I have are five pin (DIN?), and though the middle port is seven pin, I've already experienced successfully using a five pin cable with a seven pin port (on my Elekronika BK-0010-01).
