Introduction

Speccy emulates once popular Sinclair ZX Spectrum home computer, its upgraded versions, and its clones. As Speccy is written in a portable C programming language, it may run on many different platforms, such as desktops, palmtops, cell phones, set-top boxes, newer videogame consoles, DVD players, and even digital cameras. Currently available are Speccy binaries for Windows and MSDOS, with ports to more platforms coming soon. You can always get the latest Speccy binaries and support files from

Although I had done some ZX-related work in the past and even maintained comp.sys.sinclair FAQ at some point, for many years I abstained from writing a Sinclair ZX Spectrum emulator. It was mostly due to the fact that there were so many other Spectrum emulators around, so writing another one seemed redundant. On the other hand, the lack of a Speccy emulator felt like a gaping hole on my resume :). So, here it is, yet another Spectrum emulator, trivially named Speccy. Currently, Speccy is not a commercial project but rather a test bed to try out different things before introducing them into my other emulators. Thus, feel free to use it as you wish (as long as it is not commercial). If you find a bug, have an idea on the further Speccy development, or would like to port Speccy to a new platform, please, let me know either by email, or by using the EMUL8 discussion group.

Since its creation, Speccy has been ported to Windows, MSDOS, and Symbian platforms. The latter works on Nokia's phones running the 3rd edition of the S60 software. For more information on Speccy-Symbian and my other Symbian projects, see

The current version of Speccy has the following features:

Frequently Asked Questions

  1. How do I load programs from tape?

    To load a program from tape, load the tape into the emulator, then either select the TAPE LOADER in the 128kB mode or press [J], [CTRL]+[P], [CTRL]+[P], [ENTER] in the 48kB mode. Your Spectrum is now ready to load a program from tape. To start the tape, press [F5] or go to the builtin menu ([F4]) and check the TAPE RUNNING option. The loading process will start.

  2. How do I speed up tape loading?

    Tape loading happens at the same speed it would happen on a real Spectrum. To speed it up, press the fast-forwarding button ([PgUp] or [F9]).
