Running Apple ][ Software on a Commodore 64 — Silently

In 1984, a Canadian company called Mimic built the Spartan: a hardware add-on that converted a Commodore 64 into an Apple ][ compatible machine, letting users run Apple software on cheaper Commodore hardware. The concept had real market logic. Apple software libraries dwarfed the C64's at the time, and the price gap between the two machines was significant.

The execution killed it. Mimic announced the Spartan in 1984 but shipped nothing to customers for roughly two years. By that point, C64 software had exploded, the price argument had collapsed, and Apple had already discontinued the Apple ][+ that the Spartan was designed to emulate. Mimic also ran ads featuring a mime, or possibly a clown, to promote a computer peripheral. The mime appeared in every ad and on the product box. No explanation has surfaced.

The full piece from Such Bad Tech Ads is worth reading for the ad archaeology alone, but the real pull is the timeline breakdown of how Mimic's delay turned a plausible idea into a footnote. The comparison to later conversion successes like the Intel Inboard/386 raises an honest question about whether earlier execution could have changed the outcome, or whether the mime doomed them regardless.
