M4 Board still alive and kicking

The M4 board for the Amstrad CPC computer series has now surpassed more than 600 shipped units. And I expect to pass 700 units this year, if things continue as now.

Though there hasn’t been any recent updates on this blog for the M4 board, I have released some firmware updates adding new features.

The biggest update came last year, when I added Hack Menu which is NMI triggering with ROM/RAM remapping.
Making it possible to have “Multiface 2” like features.

For existing users it can be launched via the web-interface or by manually soldering a switch onto the board.

As can be seen on the video above, it is now possible to save game progress and re-load it again, using the popular .SNA format, which is compatible with many emulators aswell.

However it is still in beta so it can crash under some circumstances.
I expect to do some major software improvement to this Hack menu.

Meanwhile I updated the PCB once again to have this new Hack button.

The PCB now being version 2.5C.

M7 Board

So what about M7 / Galaxy Board / Zen80 board ?
It’s not cancelled, but I haven’t really worked on it for a long while, I do have some overall changes in mind and hope to pick it up again.

Imperium Solo – USB joypads

I also made a USB to joystick adapter called Imperium Solo, which is also partial functionality of the Galaxy board. Its intended use is to be able to connect USB joypads and mouses to the joystick port. For now it supports CPC, but later it’s meant to be working with ZX Spectrum +2/+3, C64, Atari ST and Amiga. Or well lets wait and see 😉

I will update more on this soon, as I am awaiting the final PCB.

  1. All your projects look fantastic. Can you send me info on buying an M4 card for my 6128? Thanks, Lampros

  2. Hello Duke,
    I would like to acquire a M4 board for my CPC 464.
    I hope it is still possible,
    Thanks in advance for your e-mail
    I live in France

  3. Hi Duke,

    I thought my CPC 464 was dead, but managed to fix it today! The main power switch had failed open, so it simply wasn’t letting any power through to the chips. I shorted the power switch’s wires together and success! That was an easy fix…

    Time to celebrate by buying an M4 board. My 464 is a UK one, so I think I’ll need the adapter for my edge connector too. Please could you send me an email? Thank you so much!

  4. Hi there,

    I would love to buy one of those beauties from you. I want to use it on 464 and 6128. Think I need different cables to connect ? Do you provide those too ?

    Please send me an EMail for details abou purchasing this 🙂

    Thanx
