Things are tough right now ...

They're tough for everyone :( But when coronavirus hit here in the UK, the museum had to close its doors to the public, and we lost practically all our income overnight.

Please Donate Via Just GivingNo visitors, no workshops, no events, no school visits... no income. We know that things are tough for everyone right now, but if you can afford to help us through these tough times please donate what you can.

Stay safe, stay at home! There's over 36,000 exhibits here! That should keep you occupied for a bit - get searching!

This article is intended to show how the RCA COSMAC CDP1802 MPU can be used in a fairly simple computer system, and to highlight the advantages of using this particular MPU over other types of MPU.
26 In praise of the PDP-11 [Article]
Mike Lord
Most people who come into contact with the PDP-11 soon develop an affectionate enthusiasm for it. This article attempts to explain why, and also to show why a design almost 10 years old is still held up as a standard against which new mini and micro computers are judged.
29 Programming - A personal approach [Article]
Stephen Holden
Learning to write programs, is in a large measure, finding out that you are fallible just like everyone else. Since computers are very "Literal minded" they will cheerfully do exactly what you tell them to do- even when you give them the wrong instructions.
32 Do-it-yourself Micros for Companies [Article]
Richard R. Waller
This is addressed to the 90% of current microcomputer buyers who are paying for equipment with company money. It takes the form of a straight question. Are you man enough to make a case for real money and put up a plan to your company to do the job properly?
34 Johann Sebastian Byte [Article]
Michael Inggs
One is becoming so accustomed to the power of computers these days. It perhaps is not surprising to most to hear how they can fairly simply be set to work to play music. This article will attempt to show some of the ways the most rudimentary microprocessor system can be made to play simple tunes which have been programmed from sheet music.
37 Nascom 1 Z80 Microcomputer Kit [Advert]
Advert for the Nascom 1 Z80 Microcomputer Kit.

48 A guided tour of the Z80 [Article]
Neil Harrison
Early in 1976, Zilog introduced their 8 bit microprocessor, the Z*). In spite of its high initial cost it received an enthusiastic welcome from the well established american personal computing community who were quick to appreciate its capabilities.
52 8080 Debug Routine [Article]
Margaret Berg
Full source code and commands for a 8080 debug routine.
56 MK14 - the only low-cost keyboard-addressable microcomputer [Advert]

56 Putting bits in their place - A simple 2708 Programmer [Article]
David Goadby
At the time of writing the 2708 is available for less than 11 in single units. The popularity of a chip is invariably in inverse proportion to its cost, so the 2708 is rapidly becoming an amateur standard, at least until something cheaper comes along!
59 Punch Lines - Interfacing a Westrex Punch to a 6800 mpu system [Article]
Mark Colton
A paper tape punch is a useful piece of equipment to have in an MPU System. Paer tape is a widely used medium, and provides a fairly indestructible copy of any saved programs and data.
62 Pattern Recognition - The ultimate interface [Article]
Dr. David Hand
Many of the readers of this magazine will have heard of computers which can recognise spoken commands, read printed matter, or check if signatures are genuine, and will be wondering if it is possible to program their own computer system do do similar things.
66 Making a splash - Compute your football pools entry [Article]
F. Heathman
I am well aware of the verdict of mathematicians, that there is no advantage to be gained by the use of a computer to predict the results of football pools, but it is never-the-less fascinating to attempt to devise an algorithm that gives good correlation with the actual scores and draws.
67 Personal Computer World Show 1978 [Advert]
An advert for the PCW Show to be held at the West Centre Hotel, London SW6, 21-23 September 1978

This article is based on the experience that most people are to a greater or lesser extent ignorant of the information resources available in libraries.
74 Computing and Deafness [Article]
T. J. Allen
Deafness is perhaps the most neglected handicap there is and yet surprisingly the one where computing and electronics in general could have great significance. As a teacher in a secondary school for the deaf, I am especially interested in the impact computer techniques and microprocessors in particular could have in deaf education.
76 Book Review - Illustrating Basic (A simple programming language) [Review]
