What's the options? ;)


I think this one is for me, all inclusive:

C1) Soldered and tested including WIZ812MJ module 45,50£ including postage.


I will buy it in July Paul.

Best regards.

Due to currency breakdown I will no longer sell in £.
If you like to buy from me, please PM me for momentary prices in €.
So simone was the last whose payment in £ was accepted.
kind regards Paul

Just to keep you informed, here are the available options for the Hardware:

A) PCB only plus programmed GAL without WIZ812MJ module: 13€ including postage
A1) PCB only plus programmed GAL plus WIZ812MJ module: 40€ including postage
B) Kit without WIZ812MJ module 25€ including postage
B1) Kit plus WIZ812MJ module 52€ including postage
the Kit contains all neccessary parts including what is needed for Pokemon 81xtender.
C) Soldered and tested 34€ including postage. It excludes the WIZ812MJ module.
C1) Soldered and tested including WIZ812MJ module 60€ including postage.

Please be aware that only limited supply of WIZ812MJ are available from me.

In any way you will need a WIZ812MJ module as well.
Just as an example it's available at TME,Mouser etc.

I recently sold my last WIZ812mj modules so some options are not available anymore.

Here are the available options for the Hardware:

A) PCB only plus programmed GAL without WIZ812MJ module: 13€ including postage
B) Kit without WIZ812MJ module 25€ including postage. This Kit contains all neccessary parts including the Pokemon 81xtender.
At the moment I don't offer soldered versions because having no wiznet module I can't test it.

In any way you will need a WIZ812MJ module as well.
Just as an example it's available at TME,Mouser etc.

Jegs asked somewhere else:
jegs2 wrote:Dang, I drop off the grid for a year or so ... and somebody develops LAN hardware for the ZX-81?

Cool! Have a ZXspand ... will this new gizmo work in conjunction with it on my T/S 1500?
That depends a little on how sir Morris made your TS-1500 ZXPAND Memory GAL.
For zeddynet you need RAM at 8 to 40 K.
If this is possible zeddynet will work.
Kind regards

Pictures of both sides of the PCB has been shown. Is the schematic listed anywhere?

By the way.
At the moment I don't have kits anymore.
I will order new kits on request.
At the moment the only available option is ready built and tested.
kind regards Paul

I had the idea to create an adapter stripboard to connect my Arduino Uno Ethernet shield with and W5100 to a ZeddyNet board.

(The ethernet shield is only €7 compared to Wiznet 812MJ which is €23)

Unfortunately the whole address bus and data bus is connected to GND on the Arduino Uno Ethernet shield, so it can't be done.

(You can even get a Mini W5100 LAN Ethernet Shield for €4 with shipping from China)

The ZeddyNet uses the data bus on the W5100 chip. The cheap W5100 boards only uses the RX/TX.
