This is a class action on behalf of all purchasers of the 7 stock of Stac Electronics ('"Stac" or the "Company") between May 7, 8 1992 and July 20, 1992 . Stac manufactures data compression 9 products that increase the effective capacity of storage device s 10 and are used by . owners of personal computers that use Microsoft 11 Corporation's MS-DOS or comparable operating systems . Stac's 12 "Stacker" software products provide an increase in the data storage 13 capacity of personal computers for much less cost than purchasing 14 additional "hard disk" storage capacity . By 1990, millions of 15 personal computers using the MS-DOS or comparable operating systems 16 existed and appeared to provide a large potential market for Stac's 17 Stacker products . Because Stac was first to market with a data 18 compression software product, during 1991, sales of Stac's Stacker 19 products exploded as users of personal computers found those 20 products an inexpensive and effective way to increase the data 21 storage capacity of the MS-DOS operating systems of their 22 computers . This allowed Stac to achieve significant growth in its 23 net income, as well as earnings per share through December 31, 24 1991 . 25 2 . By late 1991, 90% of Stac's revenues and over 90% of its 26 profits came from the sale of its Stacker 2 .0 data compression 27 product . Because the then currently available versions of 28 Microsoft's MS-DOS operating system did not have data compression - 1 - 1 capability, the sale of Stacker 2 .0 to owners of personal computers 2 using the MS-DOS operating system and purchasers of new computers 3 which came with the MS-DOS operating systems was the main market 4 for Stac's Stacker 2 .0 product . However, Stac's business would-be 5 severely injured if Microsoft included data compression capability 6 in its MS-DOS operating system (which Microsoft periodically 7 updated), as computer owners using the MS-DOS, system could then 8 obtain data compression capability at no extra cost by obtaining 9 the upgraded MS-DOS operating system and purchasers of, new persona l 10 computers supplied with the MS-DOS operating system would obtain 11 that capability with the purchase of their computer and have no 12 need to purchase separate software providing such capability . 13 3 . As a result of the niche Stac had found in the personal 14 computer software market, its revenue and net income exploded in 15 the latter part of calendar 1991 and early 1992 . However, Stac's 16 top executives knew by late 1991 that Stac's competitive position 17 was being impaired and that its strong growth in revenues and 18 earnings would shortly come to an end because of the increased -19 availability and popularity of competitive compression data 20 products and because (as they had learned) Microsoft intended to 21 include data compression capabilities in its next version of its 22 MS-DOS operating system, which it was then currently developing and 23 intended to release as soon as possible in 1992, and that this data 24 compression capability would be included at no additional cost in 25 Microsoft's upgraded MS-DOS system . This presented a terrible 26 threat to Stac and its insiders . Thus, they decided to undertake 27 a public offering of stock of the corporation, part of which was to 28 be sold by the corporation and part of which was to be sold by - 2 - 1 insider and controlling stockholders in an effort to raise capital 2 for the corporation to help it service the upcoming downturn in its 3 business and allow the insiders to cash out of their illiquid Stac 4 stock before these adverse facts became public knowledge, which 5 they knew would destroy the value of their stock before they were 6 able to complete a public offering . 7 4 . However, by late 1991 and continuing up to the date of 8 Stac's initial public offering on May 7, 1992 (the "Offering") , the 9 market and demand for Stac's products changed and Stac's insider s 10 and controlling shareholders realized that Stac's profitable growth 11 had peaked and that Stac would soon suffer declining revenues, net 12 income and earnings per share . By the date of the public offering, 13 Stac's insiders knew, but the public did not, that two very adverse 14 facts existed that were negatively affecting Stac's business . 15 First, demand for Stac's most important data compression product 16 (Stacker 2 .0) had weakened due to the introduction of a new popular 17 competitive product and due to customer resistance to purchasing 18 separate data compression software products'in anticipation of the 19 availability of upgraded personal computer operating systems that 20 included data compression capacity .

  • PC-DOS Notes Wendy Krieger – an Os2fan2
    PC-DOS Notes Wendy Krieger – an os2fan2 The scope of this document is from version 5.00 onwards and OS/2 2.0 onwards. The IBM releases of Windows are also covered. Files that derive from earlier versions, and continued to be used in these releases, are also documented. IBM moved from an OEM DOS to a retail DOS with DOS 5.0. This DOS is the most extensively updated version of DOS, and is the source of OS/2 DOS files. DOS 6 followed the availability of the microsoft code. 6.3 copies 6.2, while 7.0 is a rewrite of DOS. 7.1 is found in various appliance applications only, never went to retail. DOS 3 – OS/2 v1.x BASICA BASICA. and GWBASIC, is more to cater for needs from the 1980s, where these emulate the default OS on the 8-bit machines. The version numbers usually matched the DOS version, until it was stopped being developed. The last IBM compiled version is for PC-DOS 3.00. This is also the last version to include the sample files (except MORTGAGE.BAS). Microsoft provided the code for the later versions. 3.10 and 3.20 check for DOS versions, but 3.31 and 3.4 are defanged. To test for the source code, run this as soon as Basic loads. This will tell you which RND code is used. PRINT RND 0.1213501 Basic compiled by Microsoft 0.7151002 Basic compiled by IBM 0.7055475 QuickBasic and QBASIC. BASIC was dropped in the run of DOS 3.
