Sinclair Computer Edge-Connector Peripherals

The Sinclair Computer EdgeConnector Periphals Wiki has as perpus to be a centrum for collecting hardware information about devices made to plug on/in any databus connection of any Sinclair related computer, as there are eg, zx80, zx81, spectrum, Timex, ql, pc200. Most Sinclair computers have few busses on the motherboard and must be provided with extra boards connected via the (back)side of the computer.

There are severall RAMpacks, Printer interfaces, sound devices, storage devices (disk, wafer,microdrive,tape). For an upmost complete list we like to refer to eg "The Spectrum Hardware List" Our goal is to provide deeper information per item so any one can use this knowledge to implement in emulators or real hardware devices.

One off the reasons we want to maitain this WIKI-database is becouse no one has to re-invent the wheel again, since it is already done. Further it is a prove that old computer have quality and still can do much more then we once thoughed when we bought the old chaps/chips. With the right Software a Spectrum can have MultiColor, what to expect from the hardware with a new aproache? For that we need more inside information.

A databus has two sides, sending and receiving. So the Data-bus configurations per Sinclair computer AND per periphal have to be concerved to be able to have a close look on all different IN's and OUT's.

A ROM is still the Software implementation off what the CPU vs ULA produces on the severall busses. So we need to get inside information on the build off the hardwareboards and its IC's in common, but especialy the ULA's and its connections.
