Re: [N8VEM-S100:6944] Re: Reorder of S-100 8-slot Backplane PCB

add me in for two, as well. 0.098 is my vote, for what it's worth.

Thanks everyone. I'm thinking the 0.098 for thickness since I like it to be stiffer than normal as well.

The thickness doesn't add much to the cost (at most a couple dollars over the entire order.)

I've also got down the other people who have requested boards.

We have quite a few interested so I hope we can cut the price of the boards some!

I'll order by the end of the week if I don't hear of any issues with the design from anyone.

Thanks!

Hey Todd!

Please put me down for three boards as well. Looks like very useful changes.

Hi All,

Josh, that's great! I'll wait a few days to get back any more comments people might have and then place the order. 10 boards? That should help prices then!

As for thickness, I'm open to suggestions. The last boards were ordered with a 0.126 inch finished board thickness (whatever the actual delivered thickness.) Default board thickness is 0.063 inch. Thicker boards can be: 0.079, 0.098, and 0.126. Everyone please give opinions on what thickness is best.

John (and everyone else who requested boards) I will order enough for everyone who has made requests and more to keep on hand.

Thanks!

Todd

Hi John,

Thanks, I believe Todd is arranging to do the run... I just polished up the board a bit.

Cheers,

Hi Josh, great looking S100 V4 motherboard! I’m traveling a lot this month (overseas) so in case I miss it please put me on the list for one board.

I have added an update to the S100 computers “Boards For Sale” section as well and will try and do a ‘proper’ write-up on this new motherboard when it arrives.

The bus is routed to a 34 pin connector, so I thought it would be nice to repurpose this connector as the termination resistors, which is why I made it 38 pins. Using 9 pin R-Nets, from both sides will reach 32 of the 34 pins. The missing 2 pins are in the center and are wired as either +8V or GND, so they don't need termination.

The +16 and -16 are wired to the 34 pin connector and don't need termination either, so be advised that either those traces be cut or the leads of that pin of the RNet be clipped. I'm thinking of just not routing the +16/-16 since these power lines can easily be fed to the 2nd back plane if desired... your thoughts?

I’m curious about the termination R-Nets.

I thought they would all be the same, but there are only 38 pins on each of the connectors where the R-Nets will go, so four 10-position (9 resistor) R-Nets won’t fit. They will need a total of 40 pins. And they don’t make 9-position R-Nets from what I can see.

Ah, so there is both an easier way and a smarter way to do this.

Thanks for the advice.

It works fine now.

Bob,

It's the dreaded intermittent car noise. Take it into the mechanic and it stops making that noise.... This is why I put a life sized mechanic in the trunk... it works like a scare crow.

So, after you open KiCad, and before you click PCBNew, click File Open from the menu to open the whole project (schematic and PCB files). Then PCBNew will find the .brd file from that project folder.

Cheers,
Josh

Thanks for your help, Josh.

Here’s what I have tried:

Running KiCAD 2013-07-07 BZR 4022 – stable.

From here, I click on PCBNew and it starts.

(It complains about some unknown project – makes no sense – I just click okay.)

I click File Open, and I get a dialog saying the current board has been modified, and if I want to discard the changes.

I answer Yes.

Then I get an Open Board File dialog. In here, I navigate to where I have your files stored.

When I get there, it says No items match your search. I know for sure your files are there – I can see them in Windows Explorer.

Wait…as I am going through this to reproduce the problem, I now see where I can change the file type. And one of the types is KiCAD .brd.

I selected that and now I can open your KiCAD file.

I swear that was not there yesterday!

No more problems!

Hmm, I'm not sure why it won't open. Did you open the project from KiCad first?
Perhaps we can arrange a phone call and I can walk you through how I did it here?

Okay. I got my account straightened out on PBworks and I can get to the files.
But now the next hurdle: I cannot open any of them in KiCAD PCBNew. It wants a file with a kicad_pcb extension, of which there are none.

I have done minimal work in PCBNew, so I’m not sure what to expect.

Please advise.

I was going to review the work, but the link takes me to a blank page that says:
ViewFolder failed to load: Folder 'S-100 backplane' does not exist.

Has anyone else had the same issue?
