Orel BK-08 Russian Sinclair ZX Spectrum clone

So I’ve ordered one of these.

Orel BK-08 ex-USSR unofficial Sinclair ZX Spectrum clone.

It’s a ZX Spectrum clone built in the late 80’s / early 90’s in the ex-USSR (Ukraine). There were many ZX Spectrum clones manufactured unofficially in Russia, the particular example I have ordered (from eBay) is new, unused and sealed in its box.

It’s going to be a bit of an adventure to get this to display on a modern TV/monitor as it outputs a non-standard RGB + composite sync signal. In order to connect this to a modern (ish) VGA monitor, I’ve also ordered (from eBay, Amazon link below) one of these:

CGA to VGA converter

CGA to VGA converter

This board can take the low ~15Khz RGB signal in convert it to a VGA signal. None of this stuff has arrived yet, but I’ll post updates here later if I can get any of this to work.

Hi Marc. I think I probably ordered mine from the same place as you (Vladimir) since I followed your eBay link in the Spectrum 4 Ever group. It is going to be interesting getting it going (when I receive it) since I am in the US – NTSC/110V.

The unit is in the mail, hopefully I will see it within the next couple weeks. I already received the CGA -> VGA adapter. I’ll update here once I get all the pieces together.

Aw, sorry, I didn’t notice that you’re already on Spectrum 4 Ever!

And yeah, I was wondering why you couldn’t get your Orel to work, but you don’t have a PAL compatible tv and will be using a monitor instead. I get it now 🙂 I just don’t think you can get BRIGHT 1 to work this way, unless you use resistors and stuff.

Anyway, the invitation still stands!

Sure – be interesting to swap notes on the Orel units!

Did that video converter work properly for you?

No, I did not get it to work correctly. 🙁
