Spectre GCR

It is Small's third Macintosh emulator for the ST, replacing his previous Magic Sac[4] and Spectre 128.

[5][6] Data Pacific originally planned to sell Magic Sac as MacCartridge, a complete product incorporating the Apple Macintosh ROMs, but after Apple legal threats, the company instead sold the product without ROMs.

[7] As of 1989[update] an ST with Apple ROMs and a product like Magic Sac or Spectre was the only legal Macintosh clone.

[9][10] The manual claims the speed to be 20% faster than an actual Mac Plus with a 30% larger screen area and resolution.

[11] Nick Walker of Personal Computer World in January 1987 said that McEmulator "not only works, it runs software 20 per cent faster than the Macintosh".
