M4 Board – Amstrad CPC WiFi, recap 2016

The interest for this project turned out to exceed anything I ever imagined and lots of units have been produced.

 

 

 

 

 

Showing some of the batches that was made, in my “garage” production.

The firmware was vastly improved, since the initial version.


Some key points:

  • Romboard was extended to 32 roms & ability to remap lowerrom
  • Autoexec.bas execution on start up
  • Long filename handling
  • NETAPI for native applications

Supporting the entire Amstrad CPC range from 464 to 6128 plus.

Firmware updates are available here:
http://www.cpcwiki.eu/index.php/M4_Board

And a link to latest beta firmware, documentation and development info can be found here:
http://www.spinpoint.org/cpc/m4info.txt

Software:
I released the source code of the z80 assembler part of the M4 DOS here:
https://github.com/M4Duke/m4rom

With this anyone can make their own custom build if desired and replace my build simply by copying M4ROM.BIN to the root of their sd card.

Other examples, handling the NETAPI from your applications:
https://github.com/M4Duke/M4examples

And of course the cpcxfer program, to conveniently transfer files between pc and the amstrad cpc over WiFi via commandline.

Prodatron wrote support for M4 in his great SymbOS (http://www.symbos.de)
Giving you the ability to chat on IRC, download files via wget, copy files between floppies & sd and much much more.

Very impressive.

Look into this thread for download and installation details:

A nice video for the CPC strong hold in Spain by Professor Retroman.

2017
There is still so much more that could be added in the future.

Keep an eye on this thread for future updates & info.

  1. hello.

    very nice set of cpc cards.. !

    i am looking for a simple card to plug directly into the back of a CPC464 that will allow me to load files from a memory card. (i don’t care what kind of card..) I don’t need a wifi or disk interface etc.

    I don’t have a DDI-1 interface, just the normal CPC464.

    Do you sell such a card ?

    thanks

    1. M4 board can be plugged directly into a CPC464, no DDI-1 interface needed. You can access files from the microSD just as in the video in previous post.
