New Product: QL Power Converter

Been a while but have had a busy year. Amongst the odd projects that I’ve been working on is a power converter for the Sinclair QL. The original power supply is fairly hard to get and its unique power connector means that there hasn’t been an off the shelf alternative – until now.

QL Power Converter

The converter takes a nominal 12V input from a customer supplied power supply (plug pack or other suitable power source with a 2.1mm DC plug) and converts this single voltage into the DC and AC voltages the QL requires. The converter comes with a custom 3D printed case and QL power plug.

Protection is provided with the converter returning to standby if excessive power draw is detected or if the external power supply is of insufficient power rating.

There are a few up for sale on SellMyRetro right now if you want to grab one 🙂

Coming soon will be a similar product for the +2A/B and +3 Spectrum computers.

Enclosures for ZX and QL vDrives

Finally, an enclosure* to go with your vDriveQL or vDriveZX!

No need to dismantle an existing Microdrive for the case, you can now buy a custom 3D printed enclosure designed specifically for the vDriveQL or vDriveZX (there are two case styles to choose from).

Case includes a LED upgrade kit (rectangular LED + resistor). Various offers are available on the ususal sites (SellMyRetro and Tindie) for the case by itself are bundled with a vDrive and other options.

Acknowledgements: Michele Perini for the original 3D case model

*Note the enclosure is 3D printed and although the visible surface finish has been optimized there are still some minor surface imperfections due to the printing process.

Installation instructions for the QL case can be found here,  and for the ZX case here

vDrive QL now on Tindie

As well as the vDrive ZX, I now sell the vDrive QL on Tindie. You can check out all I have available here:

Although not featured directly in products, I also have available Microdrive cables and the vMap (if you’re buying a vDrive QL) which can be selected as options while making a purchase.

Products are still available through SellMyRetro if you prefer.


vLA-1 update

Some months ago (it’s been more than three I know) I mentioned that the Interface 1 replacement (vLA-1) that I had been working on would be available in limited numbers.

I’ve received valuable feedback from testers (thanks in particular to Brendan Alford) and finally everything looks ready to go.

The vLA-1 is a pin-for-pin functional equivalent of the Interface 1 ULA and is suitable for both V1 and V2 versions of the Interface.  As most know, the original ULA is prone to overheating spectacularly, melting an unsightly crater in the plastic casing. Note that due to the lack of space in the original Interface 1 case, the original ULA will need to be removed and the vLA-1 soldered in its place.

The vLA-1 will be sold on SellMyRetro in a choice of the following deals:

  1.  One  vLA-1 –  £24.50 each + £5 shipping
  2.  Two vLA-1  –  £22.50 each + £5 shipping
  3.  Three or more (up a maximum of five)  vLA-1 – £20.00 each + £5 shipping.

To keep the cost down the shipping option is untracked. This has proved reliable in the past but if you have other shipping requirements then please contact me directly on and I’ll provide a quote.

To get alerts when the vLA-1 is available just set a keyword watch in SellMyRetro for ‘vLA-1’. I’ll also let you know through this website, some of the FB sites, and twitter (Charlie@vdrivezx).

The vLA-1 will also be available to preorder but there may be a short wait as I’m set up to supply in batches rather than making to order.

And, of course, I’ll continue to make vDrives.
