from Practical Electronics, June 1979.
Science of Cambridge : the new MK14.
Simples, 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 :
Extra RAM - 256 bytes
16 line RAM I/O device (allowed for on the PCB) giving further 128 bytes of RAM.
Low-cost cassette interface module - which means you can use ordinary tape cassettes / recorder for storage of data and programs.
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.
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.
8-digit, 7-segment LED display.
8 x 512 PROM containing monitor program and interface instructions
256 bytes of RAM
Single 8v power supply
Space available for extra 256 byte RAM and 16 port I/O
Edge connector access to all data lines and I/O ports
Every MK14 kit includes a manual which deals with procedures from soldering techniques to interfacing with complex external equipment. It includes 20 sample programs including math routines (square root,etc), digital alarm clock, single-step,music box,mastermind and moon landing games, self replication, general purpose sequencing etc.
Designed for fast, easy assembly
