Amstrad CPC WiFi
« on: 09:36, 07 May 16 »
Hi guys,

I have hacked together an expansion board for the CPC, letting it connect to your home router/accesspoint via WiFi.
It also features a romboard and sd card for file access.

It's a bit rough at the moment, but the basics do work.

Please check it out at:
spinpoint.org – Duke's tech ramblings…


Let me know what you think - Any use, or plain madness :) - It was fun doing atleast.

Works on entire CPC range (from 464 to 6128+)

Regards,
Duke

Update!

Prices:

M4 Board with MX4 (IDC) connector price   40 euro
M4 Board with Edge connector price   43.5 euro
Adapter PCB unassembled/assembled (Amstrad CPC WiFi, new version is more compact) 6/7 euro
Centronics to MX4 (IDC) cable, 7 euro  (for CPC+ and Schneider CPC6128)
Edge to MX4 (IDC) cable, 6 euro

Shipping cost to most of europe <100g 3.5 euro
Shipping cost to most of europe <250g 7 euro

2 boards is possible with <100 gram

About connectors:
Regular CPC has edge connector. CPC+ and Schneider CPC (only 6128?) have centronics connector.

Documentation:
Instructions on usage (and a bit of developer information, WIP).

Need a board, then send me a private message (with your email address), and let me know which connector you need on it.

Well I didn't tell about it, because I wasn't sure if it was going to be possible (getting rom mapping to work was horror!) or if I would give up on it :)

The rom that makes it possible is one I wrote, it's loaded into the RAM of the MCU and currently mapped as rom7 to replace AMSDOS (more game compatiblity, when loaders disable other roms and re-enable only rom7). It's just a tiny hook of the CAS_ routines and some code to communicate with the M4, of course some RSX commands too.
However it can run as another rom as well (ie. rom6), as it doesn't have any real disc routines yet, that is needed if one wants to access real discs.

I'll never get tired of seeing things, that most people said was impossible, suddenly become a reality.  :)
Currently working on "8-bit Memoirs"; a diskmag-like collection of stories about retro computers I remember from my childhood.
Will be released as a blu-ray ISO, playable with software like PowerDVD and VLC - and of course in real blu-ray players including Playstation 3 and X-Box One.

I haven't done a strict cost calculation, but I think it would be about 40 euro + shipping, so a bit high, but I have to pay 25% vat of the amount.
This is without cable, the connectors are pricey, but I could make a version with edge connector on the pcb, so it plugs directly into the CPC (none plus and schneider with centronics).

Have you thought about using the MX4 connectors that Toto established? For those that don't have an MX4 a cable can easily be made with edge or d connector.

I'd suggest a way compatible with the MX4 cable, brcause that way anyone can acquire or make the cable needed, or even use the MX4 cable.
