Some people seem to like these more than their ZX Spectrum goodies 😉
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
If not in stock, lead time is about 3 weeks –Some parts have to come from China |
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.

Link for EEPROM programmer MiniPro TL866CS
This is not a product offer, but a link to AliExpress to easily find the cheapest option for a TL866CS MiniPro universal programmer, which is currently available for about ￡19 / €23 (November 2019).
Click here to get to the AliExpress query: https://www.aliexpress.com/af/tl866cs-minipro.html?SearchText=tl866cs+minipro&SortType=price_asc&minPrice=15
Make sure you check for the correct and best price!
The TL866CS version (there are also other versions, but the TL866CS is the most affordable one) of the MiniPro supports numerous IC types, including EEPROM types like:
- AT28C256
- AM29F040B
The TL866CS works on Windows 10 and older Windows versions.
Note! Our experience with the TL866CS learned us that it is only detected by the included software, when connected to a USB2.0 port.
On a USB3.0 or higher port it seems to not work correctly.
ZX Spectrum 16K to 48K memory upgrade kit
This offer is for a kit to upgrade your ZX Spectrum 16K to 48K of memory.
For ZX Spectrum 16K board issues 2 and up (3, etc).
This kit consists of:
- A set of 8 new 4164 RAM chips
- 1x 74LS00 logic chip
- 1x 74LS32 logic chip
- 2x 74LS 157 logic chips
- 2 small wires
- An assembly manual
This kit assumes that the motherboard of your ZX Spectrum 16K has:
- 8 unpopulated IC sockets for the memory upgrade
- 4 unpopulated IC sockets for the required logic chips
Only small wires need to be soldered.
The chips should be put into the IC sockets available on your board, without soldering.
All chips are tested in a real ZX Spectrum.
Brand and model change from time to time: we’ll ship what is in stock.

Unrainer modification/fix for ZX Spectrum 128K ‘toastrack’ / +2 (grey model)
Unrainer fix to solve ‘raining effect’ with all ZX Spectrum 128K toastracks / grey +2.
What is it needed for?
A lot of (often Eastern-European) games and demos show the so-called ‘raining-effect’, which is caused by a glitch in one of the parts in the ZX Spectrum 128K ‘toastrack’ and the grey ZX Spectrum +2 models (not the black +2A or +3).
See the example pictures below.
Velesoft developed an upgrade to get rid of this problem – more information can be found at: https://velesoft.speccy.cz/zx/umbrella/umbrella.htm.
The replacement ‘unrainer’ chip
These chips have been programmed and tested.
You will have to remove the current PAL or HAL chip first – some (de)soldering skills are required for that.
A 20 pin IC socket is included – this is optional: soldering the replacement chip to the mainboard is fine as well.
One wire is needed as well – it will connect to the chip and the Z80 CPU.
I will include the wire with the package and add a small manual that shows where to connect the wire.
Manual
Read the manual here (click).
It’s not included with the package to save on shipment costs, for your benefit.
Mind the orientation of the chip!
The chips notch is aimed:
- Upwards in a toastrack
- Downwards in a +2
See the pictures of the chip locations below.
