They are - thanks! Sorted the resistor value earlier.

I apologise for any distress about the additional jumpers to route, but it the easiest way to let you have alternatives to the TLP511, whilst stil looking almost authentic.

 

[John Bennett]

OK, I think that's the lot placed

Tin - rather than just using tracks, you can draw filled polygon shapes, then right click and assign them to a net. Sega have done something similar to this for a lot of the power nets (you can see they have complicated shapes, so we're replicating it.
Not as hard as it sounds - click on the button then draw the vertices and right click when done and it fills it in. Then right click to set the layer and the net.

Cool that makes sense now, I was thinking down the line of poly caps? Could not get it! I'll give it a go, see what sort of mess I make!

Just wanted to say this thread is bloody awesome.

Today's request...

Is anyone able to get some photos of the plugs that go to the board? (please).
If possible with a ruler next to them measuring the depth?

I ask as it would be nice to put in connectors like in the graphic, with levers that grab around the plugs, but I need to know the depth of the plugs. They're deeper when the ribbon cable is looped back onto the plug via a second retainer.

E.g.

I'm trying to get a Bill of Materials together, but I'll chip in with the routing if needed.John Bennett2018-06-06 22:28:55

If it's JST-RA then two moments

I've tried to re route the problematic ACZERO and !ACZERO around under IC9 but now the software is throwing errors. If I could successfully do the routing, it does now match up. Can someone take a look at what I've done and see if you can force the software to accept it? I think I need a course ????

 

[NaokiS]

Don't have my nice calipers at the moment so here's what I have.

If it's the other type that SEGA used where the tabs lock outwards then I'll have to do that another time

I think you need to delete the old tracks and re-route them. I can see ACZERO tracks going to !ACZERO pads and vice versa.

This is truly amazing. Hats off to you all.

Is that a Sega connector?
I just had it in my head that the games probably had the ribbon looped back with a retainer, so we'd need long reach headers.

It's easy enough to just fit 2.5mm headers with no retainer, but it doesn't look as slick.

Sega "IDC-Looking" connectors are almost certainly JST-RA or AMP-?? Connectors. And acutally looking at the board it's AMP and not the JST-RA. Not sure what the connector is called but BRB

EDIT: Should point out that these are not ribbon connectors but wire connectors

EDIT2: ARGH. Right. The AC Inlet on the motor side and power connector for the logic on the lef (the 10 pin) IS wire to wire and are AMP connectors. The Yamachi connector is IDC Locking and is for IDC ribbon cable

[John Bennett]

Ah, I should've realised it was a bit unlikely to have ribbon cables for the wiring harness.

AMP Connector:

[John Bennett]

Doh, a lot of it's in the photos, dunno why I missed that.
I'll see if I can find part numbers. The worst case is bare-pin 2.54mm right-angle headers, but would be nice to get it right.

Yeah that was the problem I could not solve. I think I have done it now

As for those connectors, the original AMP style are long obsolete so the only two ways are to make replacements or just double hight right angle header pins as the original just will not fit RA IDC boxes (JST-RA does however)

 

[John Bennett]

I suppose if you can transplant the header if you're original board is knackered and I'll just source a bare-pin socket.

You guys'll have to slow down, It's nearly finished and I'm only halfway through the BOM

As I'll sort out an initial test board, if we've made mistakes we'll have a chance to sort it before ordering a batch.

 

[Outrun2]

Just reading the discussion about ribbon cable (or not) and thought I'd share a couple of rare photos I have of an OutRun PCB linked to the motor board - using a ribbon cable.

This was saved from the one and only ebay listing I've seen over the years for a deluxe motor board.

Wondered if they might help..

I don't have a cab, but have saved a ton of OutRun stuff over the years

Bit late now perhaps but here are the two control connectors:

cpu -> drive pcb: (note this is not the original cable, I replaced it for the hell of it during repair as for some reason being a resourceful fellow I had a few new ones in a box, some ribbon cable and the tool used in a vice to clamp them...)

drive pcb <-> clutch/24v power/etc:

The +5vdc power supply from the switch mode is using 'standard' sega locking connectors, not sure what they are but think someonw struglged to source identical usnits but found something usable but not locking and put it in the connector kits that were for sale for power drift/outrun, etc here.
