Because of the worldwide chip shortage, I’m really having trouble sourcing all components for the next batches of Spectranet.
There are about 50 people waiting for one, whereas I only have parts for about 20 at this moment.
The main component that is out of stock at all main suppliers, is the Wiznet ethernet controller chip.
I was able to order some small batches of these to try from less reliable sources, which I’m expecting in 2 weeks.
If these are ok, I’ll order more.

Watch this awesome review by Paul Jenkinson: The Spectrum Show EP 107.
What is Spectranet?
Spectranet is the one and only ethernet interface for the ZX Spectrum!
It was developed somewhere around 2010 (!) by Dylan Smith, who as far as we know sold about 75 Spectranets.
Around 2019 many people gained interest in Spectranet.
One reason for the renewed interest in Spectranet might be that people after getting used to storage interfaces like the DivMMC, they are now open to other advanced ZX Spectrum add-ons.
And in this internet-era the ZX Spectrum can’t stay behind!
ZX Spectrum users are now connected through Facebook and other ways of communication.
So this is the perfect time to get ZX Spectrum itself connected!
Ben Versteeg from ByteDelight restarted manufacturing in 2019.
He used Dylan’s original designs (with his permission) and designed several cases for it as well, here’s one:
The Spectranet is now available in the ByteDelight webshop: ZXSpectrum.shop.
What is TNFS?
TNFS is a communication protocol developed by Dylan Smith for Spectranet and the ZX Spectrum.
It allows a ZX Spectrum with Spectranet to connect to a server somewhere around the world, making it look like you’re loading a webpage on your ZX Spectrum.
Get over to: http://spectrum.alioth.net/doc/index.php/TNFS_server
Select between Windows, Linux, Mac and Raspberry Pi versions.
To start a TNFS instance on Windows, enter:
tnfsd [“pathname to share”]
On Windows the pathname should between double quotes, like:
I’m not sure if the double quotes are required on MacOS or Linux.
If TNFS is started correctly, on Windows a black command window will show up, showing nothing to start with.
Ones someone connects to that running TNFS server, data will be shown.
Make sure port 16384 is opened on the firewall running on the machine where you start TNFS on.
To access a TNFS server, you mount your Spectranet to it by the IP address of the TNFS machine, for example:
The underneath sites can be connected to from your ZX Spectrum with Spectranet.
So not through a webbrowser.
We will try to keep this list updated.

[to be updated soon..]
Use %opendir #n,”dir” and INPUT#n,a$ like a file.
Don’t forget to %close the channel afterwards.
