Science of Cambridge advertisement, June 1979

Science of Cambridge : the new MK14.
Simplest, most advanced, most flexible
microcomputer - in kit form.

The MK14 is a complete microcomputer with a keyboard, a display, 8 x 512 byte pre-programmed PROMs, and a 256-byte RAM programmable through the keyboard.

As such the MK14 can handle dozens of user-written programs through the hexadecimal keyboard.

Yet in kit form, the MK14 costs only £ 39.95 (+ £3.20 VAT and p & p).

More memory - and peripherals !

Optional extras include :

  1. Extra RAM - 256 bytes
  2. 16 line RAM I/O device (allowed for on the PCB) giving further 128 bytes of RAM.
  3. Low-cost cassette interface module - which means you can use ordinary tape cassettes / recorder for storage of data and programs.
  4. Revised monitor to get the most from the cassette interface module. It consists of two replacement PROMs, pre-programmed with sub-routines for the interface, offset calculations and single step, and single-operation data entry.
  5. PROM programmer and blank PROMs to set up your own pre-programmed dedicated applications.

All are available now to owners of MK14.

A valuable tool - and a training aid.

As a computer it handles operations of all types - from complex games to digital alarm clock functioning, from basic maths to a pulse delay chain. Programs are in the Manual, together with instructions for creating your own genuinely valuable programs. And, of course its a superb education and training aid - providing an ideal introduction to computer technology.
