About Interpacks

DCP Interpacks are general purpose control interfaces which offer simple easy to use control and analogue or digital inputs when connected to a computer.

Interpacks were introduced in the 1980’s and thousands have been sold with many still in use by OEM manufacturers, education and home enthusiasts, which is why they still remain available. We decided to include them on our new web site as they still have a place in specific applications and are are a foundation stone in our history. Over the years they have enjoyed wide ranging application from home heating controls to exhibition models, control education to counting bats! Some years ago there was even an article in the Sunday Times Magazine which showed scientists using them to show changes in the atmosphere inside a haunted house!
They are based on established standard integrated circuit technology which can be serviced and maintained and are ideal for educators and experimenters who have access to older computers - in fact many would argue that it is much easier and clearer to write and debug a control program in Basic than in a windows or graphical environment. They work with specific types of computers, some old ones from the 1980’s like Sinclair Spectrums and BBC Micros (which are still in use!) to an older which has an 8 or 16 bit ISA card socket and has GW Basic or most other programming language which supports reading to specific addresses.

The Interpack system is based on 2 parts - the Interpack which is the main part, and an intercard - a small personality module which clips into the Interpack and has the connector and electronics which makes it work with a specific type of computer. There is also a ‘DCP BUS Intercard’ which allows you to stack several Interpacks together.
