I don't think that I dreamt this but I seem to remember that in the early 80's EE magazine published an article to construct a space invaders game which you could play on your TV. Does anyone remember this or have a copy? |

I can't remember that at all in EE!
However Practical Electronics produced a Sports Centre game in June 1977. I think they were based on G.I.(General Instruments chips) - Tank Battle was another. (The former editor of Practical Wireless told me that the tanks used to stick to each other!)

The chap on the cover is our very own Dave Barrington! The girl was an IPC magazines secretary.
Would like to hear from readers if they can shed light on this.

I think I remember a game in EE from the 80's, memory is a bit vague, but might have been something to do with a motorcycle and jumping obstacles?
This PIC project might be of interest

There is also the Power Joy games pad, which has a load of the 80's arcade games, ready to play on a TV. |

Hi Gordon,
that's good for a PIC, but look at this for the Propeller Chip, with a similar simple circuit:

We'll be covering the Propeller in the next few articles, if I can bring myself away from playing defender!

Hi Mike, That looks pretty impressive. Should be an interesting series on the Propeller Chip. |

Thanks for the response everyone. Maybe it was the sports centre game I remember. It's amazing what time and breathing in too many solder fumes can do to your memory! |

The only Space Invader game I can find a reference for around that time was Electronics Australia's Dream 6800 diy computer project (1979). There was a code listing for a Space Invaders game for it.
Most of the other published diy games projects used the now defunct GI chip.

Gordon is right! The May 1978 issue features the "EE Teleplay" stunt cycle which involves a motorbike jumping over obstacles. The biggest obstacle nowadays is finding the AY-3-8760-1 chip on which it is based. However, the magazine itself is currently available on eBay (see http://cgi.ebay.co.uk/Everyday-Electronics-Magazine-May-1978_W0QQitemZ120531025586QQcmdZViewItemQQptZUK_Magazines?hash=item1c10357eb2).

I found the Space Invaders project I suspect you were thinking of in the November 1980 issue of ETI.
It was effectively a design for a Microtan 65 with a dedicated Space Invaders ROM, so the computer booted straight into the game. I suspect you would have a bit of fun finding the relevant EPROM for this project now.
ETI also had an earlier Pinball Video Game article, but this used a special dedicated chip.

Thanks Magman, this must be the article that I remember. |

What about this one, It uses a Pic and done in basic, I can complie the code if need be
http://wiki.picbasic.org/index.php?n=Projects.SpaceInvaderGame
and here is some more about it
http://users.picbasic.org/projects/Space%20Invaders/space_invaders.htm
I tried it a few years ago and it was fun to play |

The Pic version looks pretty good. I remember having a handheld space invader game in the 80's which used a matrix of red LEDs behind a mask of space invader shaped holes (I know this because I took it to bits, to my Mums horror). I assume that it used a multiplex technique to show the moving images on the 'screen'. It could probably be replicated quite easily using a PIC. |
