Case for M4 board, protect your Amstrad CPC Expansion
Famous and quite well known among all Amstrad users is the M4 expansion created by Duke, also known as M4 Board. And like any self-respecting retro expansion or toy, it needs a box to ensure that it works perfectly for a long time. So... Do you need a box for M4 Board? we offer you one of our designs.
The M4 expansion allows us to give our Amstrad CPC computer massive support with simulation and loading of Dsk disk images, loading of cartridges for the Amstrad Plus range and support for Rom banks accessible in typical Rombox style.
Another interesting feature is that it allows you to connect your amstrad CPC computer to the internet, making it possible to download files and thus facilitating access from another computer on the local network with a convenient and intuitive browser-based system for loading and executing files. For those who don't know the M4, it's a real piece of work, a Must Have in any Amstradian toy collection.
If you still don't know this wonderful Expansion for amstrad cpc you can learn a bit more about how it works in the article I wrote myself in the Amstrad Friends and Users website about it. M4 Board and its characteristics.
Case for M4 Board in 3D printing
The box I have designed is for the 3 button model with EDGE connector (direct to the Amstrad CPC), it is quite easy to adapt the design to the model with IDC connector (to connect to MX4 or similar multiport boards) so we will have it available soon in HobbyRetro.com.
The design of this box for M4 Board consists of 5 parts: back, front and 3 buttons of identical size. The buttons are kept in their position because the cover acts as a guide for them. The closure of the 3D printed box is with 2 screws of 1,7 x 8 mm.
Enclosure for M4 Board Edge, step-by-step assembly
Good! You have received your 3D printing or have you just printed the parts you need to assemble. Now let's see how we can make the most of it ?
Once we have the print done, the first thing we have to do is to give it a visual check, making sure that there are no small shavings or remains of the print that could make it difficult to assemble the pieces. To do this, we check the printed pieces one by one as well as the play of the pushbuttons in their recess.
That done, we have all our parts ready for assembly. Let's get on with it.
First, we place the M4 Board on the 3D printing base. With the SD card out of the board we insert the M4 from left to right allowing the wifi module to fit into the hole.
The M4 board should fit perfectly into the case, with the holes for the usb connection and the SD card perfectly aligned.
Before closing the box we can select on the M4 board from where we are going to take the power supply to the board by putting the jumper in the corresponding position.
Then we put the push buttons on the front of the case, each one in its place.
All the pushbuttons are the same size, so they can be placed in any of the holes.
Then we put the upper part or lid in place. to prevent the push buttons from moving, we place them upside down and close the box. It should fit perfectly.
Now we insert the screws in their place and screw them in with a precision phillips screwdriver.
? ATTENTION: It is not necessary to tighten the screws like those of a submarine. Please, knowledge ?
Once we have the cover securely fastened we have our 3d printed box for M4 Board assembled.
We can insert the SD card and use it in our Amstrad CPC.
