Could I get one of those too please?

You add them to every board and then un-solder them again? :P RCA for me too please.

I forgot to get one ages ago while the shop was open, so I was looking for the models and stumbled on this thread. I have a printer now so I've been printing one off today for the last few hours. Happy to run another off for cost plus postage but you might do better, (read: cheaper), to find...

Please put me down for one, thanks.

A switch with 6 contacts will likely be a DPDT (Dual Pole, Dual Throw or On-On) switch, whereas you want a DPST (Dual Pole, Single Throw or On-Off) switch. You can treat the former like the latter by just ignoring either the top or bottom row of contacts, depending on how you want the switch...

Sure, if someone loans me a board to develop/measure against.

Yes. I've used them on 1b boards and other users have confirmed they fit on 1c boards.

I've just received another batch of PCBs after my last lot sold out, if anyone still needs any.

My Proman and adapters are ready :)

Yes, I realised that mistake. A defect to be fixed in the next revision.

I think I found a handful of ISL59885ISZ on eBay, and the ISL4089IBZ was available from RS.

I didn't order this time around, but I remember having problems completing the checkout with PayPal. Every time it failed, Tindie would temporarily reduce the stock levels by whatever amount I had ordered but it would eventually restore later, either by some automatic session expiry or @everten...

I've literally just approved Mouser to ship my component order, minus some ceramic caps that appear to be unobtanium but I can manage without.

After a couple more partial prints I got all the ports in the right place so I thought what the heck, print the whole thing out in its intended black filament: I then test fitted everything together with some of the various ports in situ (they’ll be the last things I solder in normally)...

I used FreeCAD to create some 3D models, ironically for a KiCAD library for some JST connectors, and I found the UI a bit confusing but eventually managed to create what I needed. I was going to use FreeCAD again to design this bracket and found myself getting frustrated in the UI looking for...

Still waiting for components to arrive so I’ve had a go at designing a suitable bracket in OpenSCAD. Printed the first couple of mm to check all of the cutouts are in the right place and it’s mostly there: Not bad for my first attempt! I’ve got a couple of sub-mm tweaks to make; BNC cutouts...

https://wiki.arcadeotaku.com/w/Sega_Naomi_DIMM_board_and_GD-ROM documents the jumpers, although it's definitely on the DIMM board, not the Naomi.

Yes, there's two jumpers that need to be moved on the NetDIMM board and then just use a regular null-modem serial cable and you can watch the OS on the NetDIMM boot up. I can't find a reference right now but IIRC they're on the lower board.

I've got my PCBs now. I'm just waiting for the components to arrive. When I built the original clones my component order was getting messed about with line items disappearing from stock, and every time I amended it a) it took 2/3 days and then b) something else would disappear from stock. So I...

I've probably done something like this: View: https://youtu.be/ahKH19iN2SM I like and hate routing PCBs in equal measure. It's a perverse logic puzzle trying to route everything without resorting to hopping back and forth between both sides of the PCB. I am an amateur though so I've probably...
