Crystal Castles Conversion Kit

We’ve looked at arcade conversions here on the blog previously. Put simply, this was a way for arcade operators to maximise their profits. When an arcade machine got to the end of its play life and stopped taking money, why buy a whole new cabinet, when a simple swap of the game’s PCB, controls and artwork would convert a game into something new?

This was common practice, albeit something of an underground activity by profit-wary arcade owners. Many conversions were badly done, leaving ugly cabinets in their wake, and a headache for collectors some 40 years later to sort out! But not all conversions were created equal…

Atari, the darlings of the coin-operated industry, were running the gauntlet between 1979 and 1982. Arcade cabinet sales had taken off, and with the release of several arcade titles during those years that sold in the tens of thousands, they realised that their business model was entirely based on operators buying new hardware when the shelf life of their games was up. Put simply, arcade cabinet conversions, hacks and speed up kits were not good news for the company’s bottom line.

But by 1983, they realised that this market had to be catered for. The industry was slowing down, and operators were much more cost conscious. With earnings on the decline, arcade owners were focused on profit maximisation – conversion kits were very much at the forefront of their minds, rather than splashing out on brand new hardware every time they wanted new playthings for their customers to get excited about and drop coins into.

Better to get a slice of that ever increasing pie, than none of it at all.

One game released in 1983, was Crystal Castles. It was a decent enough success for Atari, with the production of 4,880 upright and 500 cocktail cabinets. They sold for $2,095 and £1,895 respectively, before being heavily discounted just months after release – perhaps a sign of the ailing market at the time.

But interestingly, it was one of the first Atari games to be produced as a conversion kit, to be sold alongside the full upright release.

A few months later in 1984, clearly looking to squeeze every last drop out of the potential of Crystal Castles, and with some fanfare, Atari announced the kits in their Coin Connection newsletter, sent to operators and distributors across the USA:


Bentley Bear is back! Now he’s gathering more gleaming new profits, adding new players to a wide base of older games……And he continues to deliver irresistable character appeal that keep players making swift tracks into both arcade and street locations! Each kit includes all the electronics, hardware, instruction manuals and graphic materials to completely convert your games.

The article goes on to say:

Order Crystal Castles kit #1 to convert an upright Missile Command. Order kit #2 to convert an upright Dig Dug, Kangaroo, Food Fight and Arabian. Watch for other Crystal Castles kits coming soon!

An interesting move for a company known for its success in selling new hardware. Operators looking to reduce sales overheads, would be given the opportunity to buy the PCB, control panel, harness and marquee at a fraction of the cost of a complete, new machine, and use these components to convert an older game.

Finding a surviving example of a Missile Command or other Atari game properly converted to a Crystal Castles is something of a rarity these days. I’ve never come across one in the flesh. But one recently turned up for sale and I thought it worthy to share the photos.

So what we have here is a Missile Command converted to Crystal Castles using the genuine kit purchased from Atari:

Note the Missile Command side art is still intact. More on this later…
Looks like the operator painted the front panel….
A custom marquee was produced allowing the conversion to be done with minimal effort. The original Missile Command speakers are repurposed and mounted onto the the new marquee
The control panel was provided complete with trackball and start/jump buttons in place. Unbolt the old panel, drop in the new one

The currrent owner of this cabinet picked this up as part of a job lot purchase recently, and it’s something of a hidden gem I think.

Also provided with the kit would have been a complete manual with full instructions:

Atari’s Crystal Castles Conversion Manual

If you’re curious as to what the recommended steps to convert the Missile Command were, you can check out a scan of the manual here.

An interesting side note while we’re talking about the conversion package; knowing that most operators wouldn’t go through with the effort of replacing the side art (as was the case in the cabinet pictured above), Atari only gave an option to request side art after the purchase:

Completing this form and mailing it back to Atari got you the Crystal Castles side art for your conversion kit. Atari knew few operators would actually do this. Sensible move on their part…
Here’s the Missile Command conversion with side art on the left, and the upright Crystal Castles arcade cabinet on the right. Not really much comparison is there? But for operators, income was more important than aesthetics, and knowing this, Atari chose not to include expensive side art that would more than likely get trashed!

So there you go. A pretty interesting chapter in Atari Coin-op History, and another stamp in Atari’s timeline, showing how the industry was changing around this time.

Many thanks to collector Greg Roder for allowing me to share the pics of his cabinet here on the blog.

Thanks for reading!

    Another great post Tony!

    I have a really nice Crystal Castles, UR,. The company I bought it from a few years ago claimed it had belonged to James J. Morgan, who was the new president of Atari at the time this came out. That and when Star Wars came out. In fact I missed buying his cockpit Star Wars they also had by only a short time. Somebody got a great game there! My. CC game is near mint. While it never seen an arcade, it was left on pretty much all the time in his home and the original monitor went bad. The company I bought it from replaced it with a good Wells Gardner.

    Also, I just happen to have that conversion flyer and manual too in my collection.
