This article is from the Apple II Csa2 FAQ, by Jeff Hurlburt with numerous contributions by others.
The //e comes in two flavors: Enhanced and unenhanced. When you start your computer, the unenhanced IIe displays "Apple ][" at the top of screen; the Enhanced IIe displays "Apple //e". Apple made an Enhancement kit to upgrade an unenhanced to Enhanced by replacing 4 chips (CPU [65C02], Video ROM [MouseText], and new Monitor/Applesoft ROMs). Apple Resource Center sells a IIe Enhancement kit for $20.00. The current IIe operating system is ProDOS-8. (The IIe can also run DOS 3.3, earlier DOS's, and Pascal.) A lot of ProDOS software requires an Enhanced //e, and sometimes 128K, too. A IIe Enhancement Kit does not include any extra RAM. You can expand a 64k IIe to the standard 128k required for a fully Enhanced IIe via an Extended 80- column card. It plugs into the Aux Connector on the motherboard. Alltech ($19.00), and MC Price Breakers ($14.95) sell such cards. Except for being able to type and display lower-case characters, the unenhanced IIe is very similar to the II+. A 128k Enhanced IIe adds a number of features including 80-column firmware and 16-color double-lores and double hires display capability. The Apple //e remains useful for four major reasons: 1) It runs AppleWorks, a simple to use, yet sophisticated Spreadsheet/Word Processor/Database. 2) It can run many games and other entertainment software products. 3) There are many Apples in schools-- an example is Louis Cornelio's room at Clairemont High School ( http://www.n2.net/clairemont/ )-- so there is a ton of Apple II educational software. 4) It is was and will always be a Personal computer. You can learn as little or as much as you want, and nothing stops you from learning about every nook and cranny in it. Ask any big name programmer in MS/DOS or Mac where they learned to program. Most of them taught themselves on a good ol' Apple II. Recommended configuration: Extended 80 Column card (gives you 128K) or RamWorks (512K to 1MB RAM), Enhancement kit (for unenhanced IIe), and a composite color monitor which can display decent 80-colume text, Super Serial card, Disk ] [ controller card, two 5.25" Disk ][ or compatible drives, parallel printer interface card, and parallell-interface printer. A Hard Drive is recommended if you use a lot of different programs. Heavy Appleworks users should add the hard disk, extra RAM, and a 4MHz or better acce lerator (like the Rocket Chip, Zip Chip or TransWarp). --Dan DeMaggio, Rubywand
