One of the drawbacks of the Spectrum Next is that it can only load TZX files by using the Pi Zero accelerator. That actually works fine in itself, but you can’t directly control the Pi, and so it doesn’t work for multi-load games because you can’t stop and start the “tape”. That’s a bit of a bugger, because many of the old Speccy games that I have enough nostalgia for to want to revisit today are multi-load games.

I needed something that would act like a real tape player, but hopefully without the flakiness.

First things first, I needed the right cable. The Next uses the same pinout as the Spectrum+3 for its tape interface and so – as with so many things retro – the peerless Iain Priddey of Retro Computer Shack comes to the rescue with his +3 tape cable, which also works nicely with the Next.

Armed with that cable, I spent some time trying to get my phone (the extraordinary Fairphone 3, if you’re interested) to output something that the Next could ingest as a tape signal, using the PlayZX app. For whatever reason, I couldn’t get the Next to pick up the audio signal though. That was odd, given that I tried stereo to mono converters and all sorts.

Happily, I came across this marvellous little device:

The TXZDuino, complete with nifty 3D printed case

It’s quite a simple device, at least in terms of what it does. You load up the SD card with TZX files, plug the 3.5mm jack into EAR on the Speccy, apply some power, start the tape loader on the Speccy and then select a TZX file with the back and forward buttons and hit play. You can pause and unpause it at will, and it also seems to be smart enough to pause itself automatically if it detects a long enough period of silence.

And to be honest, it just works. No muss, no fuss. It supports folders, and seems to read the SD card pretty swiftly. The manual stresses that some TZX files using certain custom loaders might not work unless patched, but so far I’ve not come across any problems.

For thirty quid, I’m absolutely delighted. Now, if only Fighter Bomber ran properly on the Next – I’ve been itching to try running that at 28 Mhz!
