Episode 15 - Topic Study: Ansoff's Matrix and Apple

A commercial speech recognition Blackjack program was available, after some user-specific voice training it would recognize simple commands Hit, stand. Bob Bishop's "Music Kaleidoscope" was a simple program that monitored the cassette input port and based on zero-crossings created color patterns on the screen, a predecessor to current audio visualization plug-ins for media players. Music Kaleidoscope was especially popular on projection TV sets in dance halls. Apple and many third-party developers made software available on tape at first, but after the Disk II became available in , tape-based Apple II software essentially disappeared from the market.

The Disk II single-sided floppy drive used 5. After about two years, DOS 3. This upgrade was user-installable as two PROMs on older controllers. After the release of DOS 3. Programs that required DOS 3. It was possible for software developers to create a DOS 3. Later, double-sided drives, with heads to read both sides of the disk, became available from third-party companies. Apple only produced double-sided 5. On a DOS 3. It was possible, with a special utility, to reclaim most of this space for data if a disk did not need to be bootable.

The code contained in there would then pull in the rest of the operating system. DOS stored the disk's directory on track 17, smack in the middle of the track disks, in order to reduce the average seek time to the frequently used directory track. The directory was fixed in size and could hold a maximum of files. Subdirectories were not supported. Most game publishers did not include DOS on their floppy disks, since they needed the memory it occupied more than its capabilities; instead, they often wrote their own boot loaders and read-only file systems. This also served to discourage "crackers" from snooping around in the game's copy-protection code, since the data on the disk was not in files that could be accessed easily. Some third-party manufacturers produced floppy drives that could write 40 tracks to most 5.

Most drives, even Disk IIs, could write 36 tracks; a two byte modification to DOS to format the extra track was common. The Apple Disk II stored KB on single-sided, "single-density" floppy disks, but it was very common for Apple II users to extend the capacity of a single-sided floppy disk to KB by cutting out a second write-protect notch on the side of the disk using a "disk notcher" or hole puncher and inserting the disk flipped over. Double-sided disks, with notches on both sides, were available at a higher price, but in practice the magnetic coating on the reverse of nominally single-sided disks was usually of good enough quality to be used both sides were coated in the same way to prevent warping, although only one side was certified for use.

In practice, however, this method was an inexpensive way to store twice as much data for no extra cost, and was widely used for commercially released floppies as well. Later, Apple IIs were able to use 3. DOS 3. It added support for subdirectories and volumes up to 32 MB in size. The Apple II series of computers had an enormous impact on the technology industry and expanded the role of microcomputers in society. The Apple II was the first personal computer many people ever saw.

The first spreadsheet application, VisiCalc , [61] was initially released for the Apple II, and many businesses bought them just to run VisiCalc. The Apple II's slots, allowing any peripheral card to take control of the bus and directly access memory, enabled an independent industry of card manufacturers who together created a flood of hardware products that let users build systems that were far more powerful and useful at a lower cost than any competing system, most of which were not nearly as expandable and were universally proprietary. The first peripheral card was a blank prototyping card intended for electronics enthusiasts who wanted to design their own peripherals for the Apple II.

Specialty peripherals kept the Apple II in use in industry and education environments for many years after Apple Computer stopped supporting the Apple II. Even the game port was unusually powerful and could be used for digital and analog input and output. The early manuals included instructions for how to build a circuit with only four commonly available components one transistor and three resistors and a software routine to drive a common Teletype Model 33 machine. Numerous disk images of Apple II software are available free over the Internet for use with these emulators. In addition, an active retrocomputing community of vintage Apple II collectors and users, continue to restore, maintain and develop hardware and software for daily use of these original computers.

There is still a small annual convention, KansasFest , dedicated to the platform. From Wikipedia, the free encyclopedia.
