This is a breadboard adapter to connect your ZX-Spectrum vintage computer through its rear edge-connector to external breadboard to try new peripheral circuits or simply to play with inputs and outputs of your ZX. Legend with signal descriptions is attached to the adapter for your convenience. Signals marked with stars are showed as for original 16K/48K models and may have different meaning on newer computers.
ATTENTION: Shorting power lines with ground may damage your vintage computer and/or its power adapter!

TERNARY RESEARCH CORPORATION was incorporated in New York State in June 2012 and located on Long Island (Nassau county). Our goal is to give a chance to balanced ternary electronics. Also we are selling some peripherals for retro computers as ZX-Spectrum.
Usually we ship one the next business day, but sometimes it could be a week or so if board is not yet fully assembled and/or tested.
If you chose "First Class Parcel (no tracking)" as shipping option and you live in Australia, Belgium, Canada, Croatia, Estonia, Finland, Germany, Great Britain, Hungary, Israel, Latvia, Lithuania, Malaysia, Malta, Netherlands, New Zealand, Singapore, Spain or Switzerland then we will try to add Electronic Delivery Confirmation option to the package at no charge and it will be fully trackable from the beginning to end.
