Mimic Systems Spartan

The Mimic Systems Spartan was an elusive bit of C-64 hardware that made it Apple II+ compatible. It’s one of the more interesting Apple II clones of the 1980s.

Mimic Systems took out full-page ads in all of the Commodore magazines, starting in late 1984.

The problem with it was that you couldn’t buy one, at least not in 1984 or 85. The Spartan finally appeared in 1986, and at that point, not many people wanted one anymore. So Spartans are exceedingly rare today.

But it actually seemed like a decent idea. In 1984, that is.

This is a Mimic Systems Spartan ad from late 1985 showing prototype hardware.

The C-64, you see, was a bit of a late bloomer. It sold like crazy, because it was a 64K computer that cost half as much as any other 64K computer. But there wasn’t a lot of software for it during its first couple of years on the market. And even once the software did start rolling in, most of it was game software, because the machine happened to be really good for that.

Meanwhile, the Apple II+ had thousands of software titles available for it, including the spreadsheet Visicalc. Coleco successfully marketed an add-on to allow its Colecovision game console to play Atari 2600 games, and I’m sure that idea inspired the creators of the Spartan to try a similar product to make the C-64 compatible with the Apple II+. After all, it neatly solved the lack of software to run on the 64.

Why not just buy an Apple II+ or a clone? Well, in the early 1980s, not many households wanted two computers. Space was an issue–they took up a lot more space then than they do now–and then there was the expense of duplicating all those peripherals. Not only would you have to buy two computers, but two monitors and two printers as well. So if you could buy a module to give yourself both a C-64 and an Apple II+ and let the monitor and printer do double-duty, you stood to save 600 bucks. In inflation-adjusted dollars, that was $1305. Plus, a Franklin Apple II clone cost around $1,000, so a $599 Spartan plus a $299 C-64 was cost competitive.

The biggest problem was that the hardware took forever to appear. The technology world moved much more slowly then than it does now. But even in the 1980s, two years was far too long.

By the time the Spartan finally appeared in 1986, the C-64 had a huge software library of its own, more than any single individual would ever buy. Meanwhile, the Apple II+ was old hat, replaced by the IIe and IIc, and all of the newest, best Apple software required one of the newer machines. There were several Commodore spreadsheets available by then, so it didn’t make a lot of sense to buy an expensive add-on to run Visicalc. Worst of all, by 1986 V-Tech was selling its Laser 128 Apple IIc clone for around $400. You could buy one at Sears, in the same department as a C-64 or 128.

At $599, the Spartan wouldn’t sell. They cut the price to $299. That was better. Then there was the question of how well it worked.

I only saw one review of the Spartan, in Run magazine, probably sometime in 1986. It worked fairly well, but the reviewer destroyed her Commodore disk drive trying to install the board that made it work with the Spartan. So she ended up buying a Commodore drive to replace the one she destroyed, plus an Apple-compatible drive to dedicate to the Spartan. That worked, but it turned the $299 project into a $700 project. And for $700, well, you could buy a Laser 128 at Sears, get a monitor to go with it, and run all the Apple IIc and IIe software that wouldn’t run on the Spartan. There was still that issue of finding enough room in the house for a second computer. But if you really wanted to run both Apple and Commodore software, it was a better option.

The Laser 128 sold fairly well. The Spartan didn’t. It wasn’t long after that review that the ads for the device ceased, the president of the company ran away to South America, and pretty much everyone forgot about the whole thing.

The Mimic Systems Spartan is a prized collectible now. When Spartans show up on the auction sites, I’ve seen them sell for anywhere from $500 to $1,600.
