Do you have any high res pictures of the Sprectrum Emulator PCB without components?

No, I never removed all components from a card.

I don't understand the power supply of the system bus bridge. Which voltage comes in at the DC-connector of the system bus bridge? If I connect this, do I need the normal 9V supply of the EP? I mean, when the system bus bridge is shared with the mainboard, thus the EP has to be switched on as well. Am I right?

And what happens, when I connect the bridge DC-connector without the EP supply? Doesn't go back the supply to the mainboard? If you say, no, I think that makes the Graetz-bridge.

Hi,
Well, "This man" is me
Simulator built using the documentation I found in you
I also made the bridge (fourth and fifth image from a post above).
I only have a problem with getting the appropriate edge connectors. Either they are too short or very expensive ($ 6 each).
Instead of the original system, in my bridge is a pulse stabilizer.
It can work without a huge heat sink

In addition to running the emulator I also EXDOS card. Completely rebuilt the original (there are only 6 ICs).
I am now working on their own version of the bridge. For now, uphill, but don't give up

Great work all!

The Emulator can also work with own power converter? I see the space for it.

Hello Pear, your cards are impressive...

I want to do you two questions:

Has your Spectrum emulator the fixes made by Zozo?

and,

How about doing a Microteam clone, EXDOS+RAM+ROM+possibility for a real time clock(thanks to Zozo), and more?

I say that because my Microteam has all that possibilities plus still a spare expansion bus(may be for a new Spectrum emulator...).
