The CEC issue is because of the DE10-Nano used in MiSTer / Multisystem. It does not do CEC correctly, therefore a number of dongles that plug into the standard MiSTer stack were made to disable CEC. When we designed Multisystem we added a 8 way DIL switch (SW1) so you can also isolate CEC and stop any weird problems from happening if you have othe...

I’ve discovered something interesting after struggling with getting HDMI-CEC to work in my entertainment center setup. I finally figured out what was causing the problem, my Mister Multisystem. As soon as I unplugged the HDMI cable from it everything started working perfectly. I tried a different cable to see if it was a cable problem and no change...

My situation with the PS1 core is now resolved, memtest shows #3 indicating 128MB after replacing the correct IC for U1 on my multisystem.

I wanted to update my situation, after replacing U1 on the RAM circuit with the correct part, everything is working, memtest shows #3 indicating 128 MB and my issues with the PS1 core are now resolved.

Thank you LeeW. @emiliom Emiliom you may need to adjust your BOM to reflect this, I think this is my problem, the 04 is the correct part and the 07 does not work in it's place. Also the pin header with the super long pins should ideally have a different option. I've uploaded a new BOM with the change to U1 and also separated out LED1 and added a n...

Found an issue with my mister multisystem build related to the ram, so I'll post back here if there's still an issue after I swap out the incorrect IC...

For me the green is less bright but I wouldn't say it's problematic: I aimed for a target of about 40mcd for my LEDs as I hate having blinding LEDs on things. I just now re-checked the specs on my LEDs on digikey and it looks like my red is 39.75mcd, yellow is 42.75mcd, but the green is only 20mcd. Hmm... I could have sworn the datasheet of the LE...

I may have a problem, I have been having trouble running the PSX core and found out that when I run the memtest utility from the mister menu it shows a #2 which apparently indicates I have only 64MB of ram installed. I double checked all the solder joints and even redid them all. Both 64MB chips are installed which should equal 128MB. Can someone ...

I use Update_All script to keep everything updated and to grab all the BIOS files... I have even tried using the latest nightly unstable mister build and no dice. I am using BIN/CUE games each in their own folder with the same file name. the BIOS loads when I load the core and I hear the startup sound and see Sony Computer Entertainment then it goe...

Same for me regarding the green LED. As far as the screws, no I just didn’t get those 4 20mm screws and 4 Nuts also missing. I assume it happened with confusion of when they were sometimes pre-installing the fans and at one point stopped doing that… So I noticed something a little odd. I can't see LED1 (green) unless I look directly over the top of...

I just got my official Multisystem 3D printed case in the mail and sadly they forgot to include the bolts+nuts for the internal fan Here’s my results after a quick trip to the hardware store for 4xM3 20mm flathead machine screws and 4xM3 Nuts…

Nice! Waiting for my official case to come from the UK to the me in the states.

I've verified almost all the other components now, hdmi, scart, vga, analogue audio out, ethernet, fan headers, switches, everything seems to work. As people have said the USB part of the board seems to be isolated from the rest. The HDMI and Ethernet also seem to be isolated pass-through connections. Don't have anything on hand to test the optica...

@multisystem I was wondering if there are any plans to release the PCB files for the Pi-MMS as well?

Just got the USB IC literally right after my last post. Popped it in and everything seems to be working fine, all USB are Go! Worth noting that the short 6” USB cable I planned to use didn’t work because I assume it was a Power Only cable with no Data (Hate that those exist). I’ll have to trim this other USB down quite a bit and the Very last thing...

I used Mister Fusion and Update All, don’t think I did anything specific to the de10 nano, followed this video

rezendes

I just estimated the length of the Ethernet/usb to be around 6”, I have a spare micro usb that I’ll be using once I get the last component (FE2.1 IC) and also I’ll share the Amazon link to the Ethernet cable I bought if it turns out working well. Also I kind of had to take a chance on the crystal oscillator because I couldn’t find the exact one lis...

Just got the vertical HDMI connectors in and I can now verify the height of the pin connectors for the de10 nano interface (ones with super long pins coming out the bottom) is correct and allows the hdmi dongle to fit nicely. Now I’m only really waiting on the USB IC, I won’t need the SCART or TOSLINK. I am curious though if there’s any way I can v...

I wanted to share my build progress, this is where I’m currently at after ordering all parts from the BOM @emiliom posted. I only had an issue with 2 or maybe 3 items that were out of stock but alternates were available. I’m located in the US and I am still waiting for 2 parts: USB IC and the Vertical HDMI connectors. I am having trouble ordering t...

rezendes

Thanks @emiliom and @dekay for continuing to track down proper components. I’ll be ordering and assembling mine when I return from my vacation and I’ll make sure to post the results when I’m done.

I remember changing something important that was included in the readme/documentation files somewhere in the github. EDIT I think it was the ENIG finish from the readme "Material to be 1.6mm FR4 4-layer PCB lead-free (RoHS compliant) with an Electroless Nickel Immersion (ENIG) finish. Green solder resist on both sides including vias."

rezendes

Did you have any issues with JLCPCB? I submitted the files but they've come back to me with this: "the ratio of copper pour on both top and bottom trace layer are less than 30%, and clearance bettwen traces are less than 0.127mm, it's out of our production capability as it has high risk of short circuit during production. Shall we add some co...

It looks like we will need a smart engineer to identify specific compatible component part number options that might be available to the average consumer from places like mouser / digikey in order to complete our projects. This is going to freeze my progress until such a person comes along.

Where did you get your PCBs from?

jlcpcb. I tried using pcbway first but they wanted a lot of information to be filled out before the next step where I could verify things, just seemed easier for me on jlcpcb.

I've been working on this as well. I've been putting part numbers into my list and I've got 10 that I'm certain are correct based on the codes provided in Richard's list, another 11 that I'm virtually certain are correct, but then there's lots where I need to confirm the specs and a few that I don't have a clue about. How have you made a determina...

Check PCBWay, Layout und BOM was shared there. To see BOM u must be registered.

Thanks for the suggestion. I just checked the BOM listed on PCBWay and it's the exact same one listed on the Github page, both missing manufacturer part numbers.

rezendes

Is there any way we could get a BOM with Manufacturer Part Numbers included? I've been working on making my own since you released the project as open source but I am not an engineer and I can't infer the exact required component specifications from the surrounding components. Some things are obvious and self explanatory like basic resistors/capaci...
