Duopack Real Dutch Stroopwafels – the big ones!

If you can’t get enough of these and you’re not satisfied with the mini’s I add to orders, get some of these!

PlusDlite floppydisc interface with case + Dual Floppy Drive + 10 disk set

We need about 3 working days for this product to produce.

The PlusDlite with professionally 3D printed case
+
Dual Floppy Drive set
+
10 disk set

Add the fun of using floppies on a ZX Spectrum, for a truly nostalgic experience!

The PlusDlite Floppy Disk Interface

The PlusDlite is based on the succesful MGT PlusD floppydisc interface.
The PlusD and it’s big brother – the Disciple floppydisc interface – were the best floppydisc interface available back then.
They were fast, had a really easy to use BASIC syntax, and were compatible with the most advanced floppydrives at the time: up to 80 track DS DD drives, with a maximum capacity of 800KB.
The PlusD also had snapshot functionality integrated, and came in a decent metal case.

The PlusDlite has:

An integrated Kempston joystick port
RESET button
NMI (snapshot) button!

Read the manual online here!
More information can be found at the dedicated PlusDlite website; click here!

The Dual Floppy Drive set

Manually crafted!
Also works on e.g. PlusD, Disciple, Betadisk, QL and other machines with Shugart Flopp Disk interface like BBC etc.
Including EU / UK / US power supply (the type that is needed in your country is included)

The set

The set comes with 5 Floppy discs with PlusD utilities and 5 empty formatted disks.

Shipped by registered and insured service.

DivMMC EnJOY! PRO ONE case

If you bought a DivMMC EnJOY! PRO ONE without case, but you’re thrilled by photos of the DivMMC EnJOY! PRO ONE with case, fortunately you can order the case separately.

This case is NOT for the old (discontinued) DivMMC EnJOY! ‘Black Edition’ or ‘DUO’ or any other DivMMC version such as the PRO MINI, PRO MINI *lite*.

MATERIAL USED

The cases are professionally custom 3D printed.
They have two light-guides that show led activity, two button caps for reset and nmi and a professionally printed rainbow sticker with information for the DIP switch configuration on the side.
The screws at the bottom sink into the holes of the bottom plate, so no damage is caused on your desk.

All necessary parts as described above are included with the delivery of the case.
And an added easy assembly manual will help you complete your DivMMC EnJOY! PRO ONE in the blink of an eye!

ZX Diag Cart – DIY kit

ON BACKORDER

Because of the situation in China, we didn’t get boards (pcbs) in on time.
We are still waiting for those to be produced and shipped.

We expect to have the ZX Diag Cart back in stock at the beginning of March.

You can backorder this product, which will be shipped out as soon as we have new stock.

ZX Diag Cart – DIY kit

The ZX Diag Cart will visually show all kinds of details of your ZX Spectrum, which is both looking cool and useful at the same time!

It will make diagnosing defects a lot easier:

Quickly check if voltages are present
If there is a dataline ‘stuck’
If the M1 line is working…

If you are thinking of repairing your own ZX Spectrum (any model, including many clones), this is the tool you must have!

DIY kit

The kit contains:

The circuit board with SMD parts already assembled
All parts in separately labeled bags with their part numbers for easy matching
IC’s and sockets on anti-static foam
The manual and DIY build guide

Hardware features

Autodetection of ZX Spectrum model

The ZX Diag Cart automatically detects to which ZX Spectrum model it is connected, so it can control the ROM signals on ZX Spectrum 16/48K, 128K+, +2, +2A or +3, and many clones.

LEDs

The ZX Diag Cart has 20 LEDs showing these groups of information:
– Control signals status, indicated by the blue LEDs
– Data lines status, indicated by the red LEDs
– Power lines status, indicated by the green LEDs

The speed of change of the LEDs is limited by a clever timing circuit, so it’s easier to see what signals are acting and which are stable

Slider switch

Slide it to the right to have the blue LEDs show the status of the data lines present on the edge connector.
Slide it to the left to have the blue LEDs show stages of the diagnostic software.

ROM1/OE jumper

This jumper is for compatibility with the Brazilian clones that use this line for audio.
When using a Brazilian ZX Spectrum clone (TK90X and TK95), disable the jumper (store it on one of the pins).
Enable this jumper for original ZX Spectrum models and other clones.

J1 jumper option – FLASH/SPECTRUM

When a jumper is present on pins 1-2, it will enable the integrated diagnostics software.
When a jumper is present on pins 2-3, it will have the ZX Spectrum boot as normal.

J2 jumper option – M1 Ignore / Normal

When a jumper is present on pins 1-2, it will ignore the M1 line in case it’s not working properly.
When a jumper is present on pins 2-3, it will use the M1 line.

Of course, when the M1 line of the Z80 CPU is failing, the Z80 CPU must be replaced!

Integrated Diagnostic Tools

The ZX Diag Cart comes with the ZX Spectrum Diagnostics software, developed by Dylan Smith and Brendan Alford:

The basic diagnostic tool tests:

ZX Spectrum Internal ROM
ZX Spectrum lower RAM
ZX Spectrum upper RAM
ZX Spectrum RAM paging*
Interrupts

*With 128K models

There are more features that you can launch with a key-press directly after powering up – this is shown on screen.

Needed to assemble the kit

If you ordered the kit, you additionally need these tools to assemble it:

Solder wire
Soldering iron
Side cutter to cut the legs of parts
Coffee or tea – and a beer for when you’re finished

SMD parts

The SMD parts have already been soldered on with the DIY kit.
