Fit and finish on the I2C2OLED dust cover is perfect. Even matches the recommended button colors! Go make one!

Looks really good
Any Problems with the software installation?
Leave some comments and please share some Photos with the internal cables in the i2c2oled thread if you like.

With the work being done on the Saturn core, it looks like this will require 256MB RAM to run. Is there an option with the Multisystem to add a second 128MB, so the Saturn core can be used?

no, see the below reply i had from the boards creator.

First I have heard of this, but I do love the idea. Is that screen using any port that the Multisystem or any other accessories normally use? Or is it generally an unused port?

Also going by the github page for the i2c2oled, I am going to need to manually add support for and configure this, but do I need to re-install/configure it every time MiSTer's main package is updated, or will the bash script keep working throughout updates?

It connects to the RTC module. If you use a regular RTC, you'll have a little soldering to do. If you get one from Antonio Villena, it'll have the I2C port already there to plug the OLED into. You can also do it without an RTC board, but you'll need to make up an adapter PCB with resistors. I just used Antonio's board for ease of use.
You can pull down the i2c2oled updater with the Update_All script. Once you have it, run it once to pull down images. You should only need to update when there are new cores or if i2c2oled gets new features. There's not really any configuring to do, it should just be plug and play really. I haven't touched any config files at all.

I'm in the process of gathering everything together for my MiSTer multisystem build and was wondering if anyone has been successful in using a multisystem with an MT32-Pi.

I would like to be able to also have a USB SSD plugged in for extra space, but I'm not sure if I can have both an MT-32 and a USB SSD plugged in at the same time. Do I need to plug the MT 32 into the DE10 nano?

Appreciate the help!!

MT-32 uses the serial port, which the Multisystem has. If you don't go Multisystem, you'll need an IO board for that. SSD will use the USB ports, so no issues with conflict there.

Excellent! Thank you for the help.

i2c2oled should be „mister-update-resistent“

Was just looking into this, and wondering how it could be integrated if in any way to the Multisystem. I figured it wasn't possible without an entirely different top part of the cover since a Pi would just be too big, but apparently there are versions of the MT32-Pi that use a PiZero instead of a standard sized Pi for the purpose of incorporating them into cases? I have no idea how well a PiZero would perform as a MIDI emulator over a standard PI though. IIRC the designs are still prototype anyway. But I wonder if it would be possible with a PiZero to have them be small enough to fit both a MT32-Pi and the i2c2oled into that removable front cover.

The Zero version of MT-32PI is official, so performance must at least be acceptable.

You wouldn't be able to use the official lite hat because of how the USB port is mounted, and a regular MT-32PI hat is is too big. But if someone makes a hat that's the same profile as the Zero, it should comfortably fit. Just need to edit the top cover with some screw bosses:

I wonder if Heber's working on an official multisystem mt32-pi, the inclusion of the PCI-e shaped expansion port is too suspicious for it not to do that.

Meanwhile, anyone waiting for batch 2?

they 100% have plans for mt32 as well as other addons - it's been mentioned on their discord quite number of times. no eta as far as i know.

there was a recent poll on Twitter where people could vote on which of the announced modules they wanted to see first. The majority opted for the MT32 Pi module. So that will come first.

That's cool! Do you have a link to that poll? I would like to see the other options too.

Yes, we are working on expansion 'cartridges' for the Multisystem, and also other electronics for the Multisystem/MiSTer family.

Mt32Pi 'cartridge' modules is first on the list after the recent poll.

We have lots of 'ugly' prototypes - when they start to look nicer, I will post some images and spec's etc.

Batch 2 is on the way, and batch 3 is not too far behind.

If only we could all buy DE10-nanos...

Also still very happy for any and all suggestions, we can always do more if the community wants/needs things for the Multisystem and MiSTer...

My wishlist would be:
1. MT32Pi with Pi Zero 2
2. TTYOLED Display
3. SNAC Adapter Cartridges

Thank you, I like all of those suggestions. watch this space...

Happy to hear, one of the main things I wanted that felt missing from the Multisystem was Mt32Pi. Would it be possible to incorporate the OLED display Sigismond0 showed into the MT32Pi cartridge since it seems like there might be room to put both in that area if a PiZero is used? Since the Mt32Pi usually has a screen anyway, it would be useful if when the Midi emulation is not in use, the screen functions like a I2C2OLED add-on.

Hi Everyone,

Quick update (not an April fool) -

The revised / Evolved 3D printed enclosure design for the MiSTer Multusystem is now fully published up on Printables.com -
https://www.printables.com/model/159379 ... ole-/files

If you have any questions about the files or design changes, just let me know - have fun printing and do show us if you decide to 3D print your own enclosure or make changes to the design etc.

We will also have Cartridges and various other expansion add-on's this year.

This is the Pi cartridge about to go into production, with others in various prototype stages.

Interested in any feedback / questions on the new V5 Enclosure design -
It has tonnes of quality of life updates, easier to print, virtually no support material and clean print finish -

I just watched the video about the new case from YouTube. The upgrade looks good and it's definitely the way to go if you don't have a case yet. Do you think that the owners of the original case should also upgrade?

i have to say, i love these colours.

Is this a MT32-pi Cartridge?
If yes, is this the final position for the little MT32 display?

Sorry for the question, but how was the scart cable connection?

This image was just the prototype PCB, so not yet completed the final, style, shape and functions yet. I'll pop up more images when we have a completed design. - all feedback is highly appreciated, many thanks.

The original classic case is perfectly good to use for as long as you wish. This new revision was based on all feedback and improving overall print reliability and quality on the print farm. The design incorporates as many little tweaks as possible to improve overall ease of use and function.

The new design style is a little different, so if you prefer the original, then stick with that.
