STOS and AMOS game creators

Hi, I’m Chris Payne. I was Managing Director at Mandarin Software and Europress Software for part of its history. For fun, I have written this account of my time there. Other pages on this site talk about other products we published…

One day I got called into a meeting. Peter Holmes had invited 2 guys over from Paris that he had worked with before during his time at Argus Software: Jacques Fleurance and Frederic Pinlet who had a company called Jawx which represented different French programmers. Peter invited me into the meeting to hear about one of the products they were involved in. It was called STOS BASIC for the Atari ST.

STOS BASIC had sold a couple of thousand units in France in some bland, blue packaging.

It was a BASIC programming language with a range of commands to move sprites round the screen, add music and more. This made it ideal for creating games.

Peter and I looked at each other and we knew what to do: market STOS BASIC as a games creation tool, not as a programming language that had commands for writing games.

What I was learning to do was to write the sales copy for the adverts and back of the box in my head, and from that compelling copy, add features to the final product to fulfil that promise.

So I thought through how I was going to market this, and what would appeal to Atari ST owners. As the Breakout game called Arkanoid had recently been successful, I thought it would be great to have a photo on the back of the STOS box showing a similar Breakout-style game written in STOS and saying that it comes on the included disks to show off what STOS could do. I also imagined a photo of a state-of-the-art sprite designer with a games character being created – so that meant including a sprite designer in the box too. We also included a shoot-em-up game called Zoltar which Richard designed, and a sort-of game called Bullet Train which had already been written by a French programmer before we took over the UK marketing. (We included that as it was a good demo of what STOS could do.)

Richard Vanner was the project manager for STOS. He worked closely with Francois Lionet, the creator of STOS, along with Constantin Sotiropoulos who I never met. Francois is a lovely guy and became Richard and I became good friends with him. Richard came up with the designs for Orbit…

…and the sprite designer, and Dave McLachlan, our resident computer artist designed all the graphics, doing an excellent job. (Some of the images on this page are taken from this page. I am currently trying to get permission to use them off the website owner, Mattias Gustavsson, a games programmer in Norway.)

Richard also designed a rolling demo on disk which we could mail out to stores so they could show off STOS’s abilities to their customers.

We came up with the product name: STOS: The Game Creator, I did my usual sketches for the cover artwork, and briefed Mike Ellis as per usual. This is what his team came up with, basing the central character on a studio photo of Peter Cushing, the horror movie actor, and we launched STOS in 1988…

The advert I wrote looked like this. You can see how I used the photos and captions to tell a compelling story…

STOS launched in 1988 for £29.95 (US$45) and was a terrific success from launch.

(There was considerable pressure from the Europress main board to get this product out on release. Richard had done a sterling job ensuring that the User Guide was thorough and error free. One member of the board wanted up us to stop the editing and get the User Guide printed. I and others were determined to ensure to launch this product was it was ready, and we won out in the end.)

By now I had an Apple Macintosh SE which I brought into work each day. I also bought an early CDROM drive which cost about $800. I had bought a number of public domain programs on CD from libraries in the States so I was aware of the power of public domain.

Richard found a woman in the UK called Pat Winstanley and with our encouragement she set up a public domain library for STOS programs which we promoted in the product. Later this library was taken over by Sandra Sharkey.

I created a registration form for STOS to go in every box, and offered a free newsletter to everyone who returned the card. We got thousands of cards back. I created several issues of an A5 STOS Club newsletter using PageMaker on my Mac, and included graphics from various Mac games and demos to make the newsletter more visual: images from Dark Castle, an animated comic called Shatter, and so on.

One of STOS buyers rang me up, we got chatting, he started talking with Richard, and the end result was a very nice painting program written in STOS called STOS Paint.

Francois Lionet wrote a compiler for STOS. And as this doubled or tripled the speed of STOS programs, I had the idea to feature the 2 main STOS characters from the original box, but flying out from the centre with ‘whoosh’ lines. Here’s an advert promoting both products…

I wrote a letter to our registered owners and said, if you buy STOS Compiler by mail order directly from us, we would also send them STOS Paint free of charge.

This promotion was a roaring success: we sent out thousands of letters and 36% of those people bought the Compiler! (I was amazed and delighted, and this success got me excited about the power of direct mail which eventually led me to set up my next business, LifeTools.)

I wanted to get more mileage out of STOS so Richard asked Dave McLachlan to produce a set of 600 sprites we could sell, and we called that STOS Sprites 600.

We were also approached by a company who had created a sound digitiser product, and we transformed that into STOS Maestro…

We came up with the idea of a competition called The 1989 Gameswriter Of The Year Award with a £5,000 (US$7,500) prize to promote STOS further and encourage owners to create great games and send them in to us. The winning games would be published by Mandarin Software.

This gave us some great PR.

One terrific game that came our way was from a young programmer called Darren Ithell. It was called Mouth Trap, was great fun to play, and had an amazing soundtrack…

Richard and his team chose the eventual winner: Cartoon Capers by Simon Cook and we got press coverage for this, which helped build further awareness, and sales, for STOS.

This is the only image I have found so far on the web of the packaging, care of

And this is a screenshot of it in action…

The runners-up: Mouthtrap, Skate Tribe, Yomo and Sky Strike (by Aaron Fothergill), were sold in a compilation called Games Galore for £19.95, and Richard also bundled with that a utility called STOS Squasher which dramatically reduced the size of the graphics in a STOS program. “Darn quality games!!” according to one guy on the web, and another forum poster on the same page said “Skystrike – what a cracking game! Yomo – difficult to pick up but impossibly enjoyable. Mouthtrap great fun and lovely graphics. Skatetribe – hmmm…. bit too easy. Lovely music though” – which is nice to hear.


I got a phone call one day from Bob Katz who handled the marketing at Atari. He asked if they could bundle STOS with every Atari ST for a big promotion they were doing. They weren’t offering much money per computer sold, but after talking with Meash and Diane O’Brien, the sales director, we gave the go-ahead: more people getting hold of STOS meant more sales of the Compiler and other add-on products.

AMOS The Creator

Francois Lionet started work on an Amiga version of STOS. We decided to call it AMOS. We did a teaser ad for it in the run-up to the launch, the December 89 issue of Amiga Computing magazine which was owned by Europress…

For the packaging, I drew a sketch of the word AMOS at an angle, bursting over the edges of the box, which I’d seen on other products and in some ads, and felt it would make AMOS look vibrant and larger than life. I added some musical symbols, the + x – and divide signs, and a wrote a sidenote to the designer to include the purple gorilla as my drawing skills don’t stretch to gorillas!

I wrote 4 strap lines in the lower left corner” “Create games! Create demos! Create to educate! Create ANYTHING!” – and put them in rectangular strips at an angle. I remember being stuck with the third line: I wrote something like “Create for education!” but knew it was clunky. I went to see Derek Meakin, the Europress Group Chairman and he, like the word genius he was, tweaked the words to the far better “Create to educate!”. I passed my sketch to graphic designer Mike Ellis and crew and this is what they produced. I think it was entirely their idea to add the red spaceship…

This is what’s in the box. I carried the ‘reversed out text at an angle in rectangular box’ theme across the User Guide and disks…

The User Guide ran to 290 pages, put together by Richard and a guy called Stephen who wrote most of the words. It was very well received.


AMOS came with a number of tools, including a map editor (to make fancy scrolling backgrounds); a sprite editor; and more. It sold for £49.95 ($75).

We got a great cover feature in the house magazine Amiga Computing in the May 1990 issue…

..and we got some terrific reviews in various magazines which helped propel sales.

According to this article, “AMOS has more support than any language I’ve ever seen. There is an AMOS PD disk collection (over 300 disks!) in Europe and a separate one in Australia.”


We published a compiler for AMOS for £29.95…

We created AMOS Professional too. I was going to commission Wendy Barratt to create the box artwork, but she wasn’t available, so I used another woman who I can’t remember now. This is what she came up with…

AMOS Professional sold for £69.95. According to this page, 40,000 copies of AMOS were eventually sold worldwide.


Some programmers from a company called Voodoo Software in Oxford came to see us about a 3D game they were producing for the Atari ST and Amiga. They had had a game of theirs called Xiphos published by Electronic Zoo around November 1990. Richard and I talked with them and out of that they created a 3D plugin for STOS which we marketed as STOS and AMOS 3D. I remember the programmers showing me a demo of the software in action and I was less than impressed. Then Richard sat down with it and wrote some amazing demos for it. That was one of Richard’s strengths: he knew how to create software which would wow people. We posted the demos on disk to hundreds of computer shops around the UK.

Here’s the packaging for AMOS 3D, launched in 1992 for £34.95…

…and this is the box back…

Well, that was a trip down memory lane, writing all that and digging out all the photos!

Where are they now?

Richard Vanner was so creative, inventive, enthusiastic and far more that it was inevitable he’d go on to great things. He set up The Games Creators with a guy called Lee Bamber and published Dark Basic for PC. He has created games for Facebook, and the game iDare for the iPhone.

Francois Lionet went on to set up ClickTeam, and they now publish The Game Factory 2, Multimedia Fusion 2 and more for PC.

Dave McLachlan moved to California to do graphics for computer games there.

Darren Ithell came to work for Europress full time, then went off and founded an internet business selling mobile phones.

Aaron Fothergill, who created some great demos and routines for STOS, and who I talked to many times during my time at Europress, went on to create the first game for the Apple Mac which made use of the iSight camera. We exchanged emails a couple of years ago. It was lovely to hear from him after 20 years!

If you can add to any of the above, drop me a line! I’d love to see copies of the STOS Club Newsletter I created using my first stab at desktop publishing; and the promotional letter for the STOS Compiler: my first direct mail letter. (I went on to create a direct mail business called LifeTools, selling personal growth products, which I ran for 16 years.)
