Use in real ZX Spectrum 48K #1

Open IgnacioMonge opened 9 months ago

IgnacioMonge commented 9 months ago

Hi Pawel,

I love this PCB for EPROM. I'm planning to build it for my ZX48K, but I'm not sure it can be used without any modification to the actual ZX. I know that using EPROM requires some modifications.,

Thank you in advance!

Best, Ignacio

Hi.

If you want to use the adapter, you don't need to modify anything on the ZX Spectrum board. That is what it was created for :)

Use version 1.1 from the KiCad project, not version 1.0. (In version 1.1, components are soldered on the underside to lower the structure). As a precaution, I will upload new gerbers tomorrow. The project itself is up to date.

HI, have the v1.1 gerbers been uploaded? Please advise I can't find them

Thank you, I have exported the gebers version 1.1 from the kicad project and order some pcbs. Awesome project!

userm8722 commented 9 months ago

hi where is the kicad project to export gerbers v1.1 please regards

IgnacioMonge commented 9 months ago

The kicad project in the main github page are from 9 months ago. You should use these files.

userm8722 commented 9 months ago

Hi Thanks for reply. I don't know what i'm missing? The version is 1.0 not 1.1? Regards

IgnacioMonge commented 9 months ago

Ok, let's do it easier.

Download the whole project as a zip file (go to the green "Code" button on the github webpage).
Unzip this file anywhere.
Open Kicad (I'm using version 7)
Open the file "ZXROM-4in1.kicad_pro" inside the "zx-spectrum-issue6a-replica-main\ZX-ROM-4-in-1" folder.
If you open the "ZX-ROM-4-in-1.kicad_pcb" (left side) with the PCB editor and then open it on the 3D viever (Menú/View/3D Viewer), you will see that this is the actual 1.1 version.
Now go to File\Fabrication Outputs and select Plot (say "refill" to the question). Then select "generate drill files".
Put those files in the same directory and create a zip file with them.
Now you have the 1.1 version.

Wow that's great. Thank you so much Regards

Hello guys,

I've been busy with other things, but finally updated the project. The gerber v1.1 files are already there. I'm glad you managed it :)
