Science of Cambridge (Sinclair) MK14 pcb - Revision 0 - SPECIAL PRICE OFFER
Science of Cambridge (Sinclair) MK14 pcb - Revision 0 - SPECIAL PRICE OFFER Science of Cambridge MK14 bare pcb - Gold Plated

SPECIAL OFFER PRICE (Usual price £46.50)

The Microcomputer Kit 14 (MK 14) was Sinclair's (at that time called “Science of Cambridge”) first computer. Based on the National Semiconductor SC/MP processor it was sold as a kit but has been unavailable for decades.

The MK14 was an ideal kit for getting into microprocessor systems and was very popular at the time but is now a rare and much sought after item. Because of this the prices for old units have soared even if one can be found.

The pcb offered here is a clone of the revision 0 MK14 pcb with the layout following the original layout as closely as possible. The main change has been to substitute the unreliable rubber pad type pcb contacts with footprints for readily available push button switches.

This is an ideal board for anyone wanting to build their own MK14 or if you have many of the required parts on an old pcb that is beyond repair.

All the component parts required to build the Mk14 can still be found and this pcb provides the missing part.

This is a high quality double sided board with solder resist on both sides and silk screen on the component side.

*****  Very Pleased with the board   - Paul Adams (Bristol UK)

Note that this is a 3D printed item so may need some finishing.

3D printed frame and laminated overlay for our version of the MK14 pcb which is also listed separately.

When using the mechanical key switches this can be used to give the keyboard a similar appearance to the original while retaining the advantage of real switches for reliable operation.
