My first release of 2022! This new "ZX-RC2014 Bus Interface" gives 2 expansion slots to add peripherals for the RC2014 Z80 based systems to your ZX Spectrum. Supporting all models of ZX Spectrum: 16K, 48K, +, 128K, +2, +3, +2A/B and the new ZX Spectrum Next.

In the video linked to this product page I've used both my trusty ZX Spectrum + and the ZX Spectrum Next (dev board). The interfaces I've demonstrated it with include the RC2014 Digital I/O card, the YM/AY Soundcard for the RC2014 by Ed Brindley, as well as the two RC2014 peripherals I've designed and released myself: Graphic OLED Interface and SID Soundchip Interface. (See my other Tindie listings for these two cards!)

While the ZX Spectrum assigns all even I/O addresses to it's ULA chip, most RC2014 peripherals (such as the four mentioned above and in the demonstration video) do allow you to change the base I/O address so an address not used by the ZX Spectrum itself can be selected, but best to check the specifications of any other RC2014 cards you potentially want to connect to your Spectrum via this interface.

As well as two RC2014 interface slots this board also features a reset button (still handy for 16k/48k rubber keyed Spectrums) and an external power input (micro-USB) as alternative power supply for the plugged in cards rather than taxing the Spectrum's 7805 power regulator if you are using power hungry cards.

The ZX-RC2014 Bus Interface can also be fitted with an optional ZX Spectrum Edge Connector to allow you to plug in a standard ZX Spectrum interface as well as two RC2014 cards. This is extremely handy if you have a mass storage interface on your ZX Spectrum to save having to LOAD and SAVE to cassette etc. In the demonstration video I use the through port to plug in a DIVMMC Future interface to use SD cards for mass storage with my ZX Spectrum +. If you are going to be using the interface with the ZX Spectrum Next you'll probably not need to plug in a ZX Spectrum interface so can save a couple dollars by not having it fitted. Please select the option when ordering to select if you wish to have the through port fitted or not.
