Welcome to the PlusDlite!

The PlusDlite is a floppydisc interface developed by Ben Versteeg (owner of ByteDelight.com).
The PlusDlite adds the fun of using floppies on a ZX Spectrum, for a truly nostalgic experience!

Now available in our webshop (click here)!

History: the PlusD

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.

There aren’t so many PlusD clones available, hence the PlusDlite was developed.
ByteDelight.com also offers a very nice Dual Floppydrive set, which fits perfectly with the PlusDlite and the ZX Spectrum.

PlusDlite vs PlusD

The main differences between the PlusDlite and PlusD are:
– Added Kempston joystick port
– No parallel port
– Use of smaller SMD parts

Custom designed PlusDlite case

Currently a custom designed case (as available for the DivMMC EnJOY!) is not yet available, but this is planned (ETA: end 2015).

Compatible floppydrives

Two Shugart compatible floppydrives can be connected to the PlusDlite, either 3.5″ or 5.25″, 40 or 80 tracks, single or double density, single or double sided.

You can use ‘modern’ PC floppydrives (check the information below) or even a floppydrive-emulator.
ByteDelight.com offers a nice set of Dual Floppydrives, check the webshop!

Connecting your own floppydrives

When using (older) Shugart compatible floppydrives, you can use a straight 34 pin floppycable.
Shugart compatible floppydrives have jumpers to configure the drive as DS0 or DS1.
These traditional Shugart compatible floppydrives often need 5V and 12V.

PC floppydrives (3.5″ HD 1.44MB) can be used too, and almost always need only 5V (1A) to operate.
By default PC floppydrives are not Shugart but IBM PC compatible: they are configured as drive B (DS1) by default.

To use PC floppydrives on a Sugart compatible floppydisc interface such as the PlusDlite, they must be configured as Ds0.
Sometimes this can be done on the drive itself, but this is rare and almost always need a soldering connection change.
The better way is to use a modified floppydrive cable.

Be aware! Standard PC floppydrive cables with a twist of pins 10-16, can’t be used for a Shugart compatible interface such as the PlusDlite.
To use a PC floppydrive as the first drive DS0 on the PlusDlite, a cable with a twist on pins 10-12 is needed.

ByteDelight.com offers these modified cables, and even a power supply with molex adapters for two 3.5″ floppydrives!

Using HD floppydiscs in a PC (HD) floppydrive

If you are going to use a PC floppydrive (3.5″ HD 1.44MB), and you are using HD (high density) floppydiscs for the PlusDlite, make sure to cover the HD hole on the floppydisc with (non-transparent) tape.
This will make the floppydrive behave as DD (double density), needed for the PlusDlite.

  1. Bellissima!! Come faccio a comprarla e quanto costa?? Scrivimi se mi puoi dare ulteriori notizie ciao

    • The PlusDlite will be offered on the webshop (check the link on the toolbar just under the ByteDelight logo on this page) very soon, probably this evening!

      Il PlusDlite sarà offerto sul webshop (controllare il link sulla barra degli strumenti appena sotto il logo ByteDelight in questa pagina) molto presto, probabilmente questa sera!

  2. Is it possible to use TR-DOS disks with this interface?

    I see from the manual that G+DOS is loaded from the “+SYSTEM.CDE” file on the system disk — could TR-DOS be loaded similarly (provided that TR-DOS exists as a file that could be put on a system disk in the first place)?

    • No, the PlusDlite doesn’t support TR-DOS files or disks.
      The DivMMC EnJOY! SD card interface however does support TR-DOS disk images partially.
