four-d-pi-shop is the ebay arm of CJE Micro‘s & 4D, who have the world's widest range of Raspberry Pi/RISC OS & Acorn accessories including many from third parties, most of which are famously normally 'In Stock'. Established in 1981, we have always specialised in hobbyist computing and have gained a reputation for a broad knowledge with high quality pre- and post-sales service.
CJE & 4D have, over the years, developed many of our own products for Acorn/RISC OS & Raspberry Pi computers. From the first ever 3rd party accessory for BBC Micro Model B (cassette leads) to the first ever 3rd party hardware for the Raspberry Pi Model B (Real Time Clock Module).
We are continuing to develop new products and expect to make a number of significant launches during the next year. Fourth Dimension (4D) is a sister business to CJE Micro's, having been a sibling since 1998.
