Question: Were the Amstrad CPC and Apple II Plus computers sold during the same time period?
Context: The Amstrad CPC (short for "Colour Personal Computer") is a series of 8-bit home computers produced by Amstrad between 1984 and 1990.  It was designed to compete in the mid-1980s home computer market dominated by the Commodore 64 and the Sinclair ZX Spectrum, where it successfully established itself primarily in the United Kingdom, France, Spain, and the German-speaking parts of Europe. Trailblazer is a video game that requires the player to direct a ball along a series of suspended passages.  Released originally by Gremlin Graphics for the ZX Spectrum, Commodore 64, Atari 8-bit family, Amstrad CPC and C16/plus/4 in 1986 (there was also an enhanced version on Amstrad CPC 3" disc).  It was ported to the Amiga and Atari ST. The Apple II graphics were composed of idiosyncratic modes and settings that could be exploited.  This graphics system debuted on the original Apple II, continued with the Apple II Plus and was carried forward and expanded with the Apple IIe, Enhanced IIe, IIc, IIc Plus and II. CPC Attack!  was a short-lived magazine dedicated to Amstrad CPC gaming.  The magazine was a successor to "Amstrad Computer User" magazine.  It was characterised by a strong comic-like graphical style featuring a recurring mascot - a Tank Girl-like character called Amy Strad.  Funnily enough this same character featured in "C+VG" magazine under the name "Sadie".  Originally, "Amstrad Computer User" had been a much more serious magazine than its main rival "Amstrad Action".  The radical redesign to "CPC Attack!"  was probably an attempt to appeal to "Amstrad Action" readers. First Star Software, Inc.  is a New York based video and computer game development, publishing and licensing company, founded by Richard Spitalny (who remains the company's president), Billy Blake, Peter Jablon and Fernando Herrera in 1982.  It is best known for its classic "Boulder Dash" franchise and "Spy vs. Spy" titles, originally written for home computers like the Acorn Electron, Amstrad CPC, Amiga, Apple II, Atari 400/800, Atari ST, BBC Micro, Commodore 64, and later Mac, MSX, NEC, PCjr, Spectrum ZX, and Windows.  Millions of units have been sold in both the "Boulder Dash" and "Spy vs. Spy" series of games, with "Boulder Dash" appearing in the coin-operated arcades four times. The Apple II series (trademarked with square brackets as "Apple ][" and rendered on later models as "Apple //") is a family of home computers, one of the first highly successful mass-produced text command microcomputer products, designed primarily by Steve Wozniak, manufactured by Apple Computer (now Apple Inc.) and introduced in 1977 with the original Apple II.  In terms of ease of use, features and expandability, the Apple II was a major technological advancement over its predecessor, the Apple I, a limited-production bare circuit board computer for electronics hobbyists that pioneered many features that made the Apple II a commercial success.  Introduced at the West Coast Computer Faire on April 16, 1977, the Apple II was among the first successful personal computers; it launched the Apple company into a successful business (and allowed several related companies to start).  Throughout the years, a number of models were sold, with the most popular model remaining relatively little changed into the 1990s.  While primarily an 8-bit computer, by mid-run a 16-bit model was introduced. Applesoft BASIC is a dialect of Microsoft BASIC, developed by Marc McDonald and Ric Weiland, supplied with the Apple II series of computers.  It supersedes Integer BASIC and is the BASIC in ROM in all Apple II series computers after the original Apple II model.  It is also referred to as FP BASIC (from "floating point") because of the Disk Operating System (DOS) command used to invoke it, instead of INT for Integer BASIC.  Applesoft BASIC was supplied by Microsoft and its name is derived from the names of both Apple and Microsoft.  Apple employees, including Randy Wigginton, adapted Microsoft's interpreter for the Apple II and added several features.  The first version of Applesoft was released in 1977 only on cassette tape and lacked proper support for high-resolution graphics.  Applesoft II, which was made available on cassette and disk and in the ROM of the Apple II Plus and subsequent models, was released in 1978.  It is this latter version, which has some syntax differences from the first as well as support for the Apple II high-resolution graphics modes, that most people mean by the term "Applesoft". The Motorola 6845 (commonly MC6845) is a video address generator first introduced by Motorola and used among others in the Videx VideoTerm display cards for the Apple II computers, in the MDA, HGC and CGA video adapters for the IBM PC, and in the Amstrad CPC and BBC Micro.  Its functionality was duplicated and extended by custom circuits in the EGA and VGA PC video adapters.  It is related to the later 6545 manufactured by MOS Technology (Commodore Semiconductor Group) and Rockwell (in two variations) and was cloned as the Hitachi HD46505 which was used in many Japanese computers from Sony, Sharp, Panasonic and Casio, and later was used in Videx's UltraTerm card). The Apple II Plus (stylized as Apple ][+) is the second model of the Apple II series of personal computers produced by Apple Computer, Inc. It was sold from June 1979 to December 1982. The Amstrad CP/M Plus character set (alternatively known as PCW character set or ZX Spectrum +3 character set) refers to a group of 8-bit character sets introduced by Amstrad/Locomotive Software for use in conjunction with their adaptation of Digital Research's CP/M Plus on various Amstrad CPC / Schneider CPC and Amstrad PCW / Schneider Joyce machines.  The character set was also utilized on the Amstrad ZX Spectrum +3 since 1987.
