Question: Are Prológica CP-400 and Atari ST both personal computers?

Passages:
Atari Corporation was an American manufacturer of computers and video game consoles from 1984 to 1996.  Atari Corp. was founded in July 1984 when Warner Communications sold the home computing and game console divisions of Atari, Inc. to Jack Tramiel.  Its chief products were the Atari ST, , Atari 7800, Atari Lynx, and Atari Jaguar.  The company reverse merged with JTS Inc. in 1996, becoming a small division, which itself closed when JTS liquidated the IP to Hasbro Interactive in 1998. Megamax C is a K&R implementation of C for the Atari ST, Apple IIgs, and Macintosh computers.  Sold by Megamax, Inc., based in Richardson, Texas, the package includes a one-pass compiler, linker, editor, resource construction kit, and documentation.  In the early days of the Atari ST, Megamax C was the primary competitor to the Alcyon C compiler from Digital Research which was included in the official developer kit from Atari.  According to a review in "Antic" magazine, Megamax C compiled a small benchmark program six times faster than Digital Research's compiler. In the middle of 1984 a Brazilian company called Prológica, which made its own versions of 8 bits US computers, brought to the Brazilian market a new equipment for its personal computer series called "CP" (shorten of Personal Computer in Portuguese). FreeMint, MultiTOS, and a few more obscure OSes are all successors to TOS the proprietary operating system of the Atari ST computer.  Later models of the ST Computer were called the TT and the Falcon.  TOS stands for The Operating System or Tramiel Operating System, as Jack Tramiel was the owner of Atari.  GEMDOS itself was a near clone of DOS, the IBM PC OS.  This was most visible to users in the 8.3 character file naming system.  Like all personal computer operating systems of the day, TOS was single tasking.  GEM, the graphical user interface, was licensed from Digital Research and was not included in Apple's lawsuit against DR, thus the Macintosh like appearance and ways of doing things remained on Atari computers.  As time went on, the big goal for the ST within and without Atari was to have a multitasking TOS. Happy drives are series of disk drive enhancements for the Atari 8-bit and Atari ST computer families produced by a small company Happy Computers.  Happy Computers is most noted for the add-in boards for the Atari 810 and Atari 1050 disk drives, which achieved a tremendous speed improvement for reading and writing, and for the ability to "back up" floppies.  Happy's products were among the most popular Atari computer add-ons.  They were still in use and active in the aftermarket as of 2009. DTACK Grounded was a computer hobbyist newsletter published from July 1981 to September 1985 by Hal W. Hardenberg.  Subtitled "The Journal of Simple 68000 Systems", the newsletter was dedicated to the proposition that the Motorola 68000 CPU could be used to build simple fast computers.  In 1981 this was a revolutionary idea.  This was before 68000-based personal computers like the Apple Macintosh, Commodore Amiga, and Atari ST had been created.  In 1981 Motorola was marketing the 68000 solely as a CPU for high-end Unix workstations.  Hal believed that the 68000 could be used as a simple embedded microprocessor as well, and used the newsletter to explain how to do that. The ATASCII character set, from ATARI Standard Code for Information Interchange", alternatively ATARI ASCII", is the variation on ASCII used in the Atari 8-bit family of home computers.  The first of this family were the Atari 400 and 800, released in 1979, and later models were released throughout the 1980s.  The last computer to use the ATASCII character set was the Atari XEGS which was released in 1987.  The Atari ST family of computers used the different Atari ST character set. The Atari ST is a line of home computers from Atari Corporation and the successor to the Atari 8-bit family.  The initial ST model, the 520ST, saw limited release in April-June 1985 and was widely available in July.  The Atari ST is the first personal computer to come with a bitmapped color GUI, using a version of Digital Research's GEM released in February 1985.  The 1040ST, released in 1986, is the first personal computer to ship with a megabyte of RAM in the base configuration and also the first with a cost-per-kilobyte of less than US$1. <P0-S0> ST Amiga Format was a computer magazine that covered the Atari ST and Amiga computers. <P0-S1>  It was published by Future plc to cover the ever growing market for the, then-new, 16-bit home computers. <P0-S2>  Issues were equally balanced with coverage for both Commodore Amiga and Atari ST systems. <P0-S3>  Issue 1 included a main feature 'ST or Amiga? <P0-S4>  The Choice is Yours', where the pros and cons for each machine was examined. <P2-S0> Page 6 (subtitled "Atari Users Magazine", and later known as New Atari User) was an independent British publication aimed at users of Atari home computers. <P2-S1>  It was published between 1982 and 1998. <P2-S2>  The computer magazine supported both the Atari 8-bit family of computers (400/800/XL/XE) and the Atari ST range.
