contacted by a user group in Pennsylvania, leading to him shipping all the disks with source code to the group. Through this period the number of drivers expanded from the original 10 to as many as 159 by the time he sent the code off. AtariWriter Plus After the purchase of Atari by Jack Tramiel in 1984, the new Atari Corporation began an effort to introduce cost-reduced versions of the 8-bit lineup, the XE series. Among these was the 130XE model, which used bank switching to support 128 kB of RAM. For these machines, a new version of AtariWriter was introduced in November 1985, AtariWriter Plus. By this time, Robinson had left Datasoft and started his own company, Micro Fantasy. Robinson continued to be the primary programmer on the core program, while Ron Rosen handled the mail merge, and R. Stanley Kistler the spell checker. Jeffrey Bass wrote the documentation. The new version added a huge number of features, giving it parity with the original Atari Word Processor in terms of power. Practically every part of the program changed in some way. Adding all of this functionality meant it no longer fit on a 16 kB cartridge, and it instead shipped on two flippy disks, one of them with the "normal" version on one side and the 130XE version on the other. In contrast to the original, which booted in less than a second, loading the new version from disk took almost a minute. The main difference compared to the original version was support for horizontal scrolling to allow direct editing of wider documents. This had been one of the notable features of the original Atari Word Processor, which used the platform's hardware assisted scrolling system to rapidly move the entire document horizontally to allow editing at up to 132 columns. The new AtariWriter worked in the same way, but expanded it even further to a maximum of 249 columns. Another change was that formatting options were set through a global menu, rather than on-screen within the document. A new save-as-plain-ASCII option allowed these codes to be easily stripped out for sending the plain text to other users. Another major feature taken from Word Processor was two-column layout. Dozens of other more minor changes were also included that made common operations much easier. The new version also greatly expanded printer support. In addition to the original set of Atari printers
