Selling for over 10 years, the Apple II line was very successful and
the II+ had a few new features over the standard II including:
new ROM holding the AppleSoft Basic (floating point version written by Microsoft)
new auto-start for easy start-up and screen editing
increased ram (to 48 KB)
Having sold between 5 and 6 million machines during its lifetime, the Apple II was certainly popular, especially in school systems in the United States (Commodore machines ruled in Canada). The Apple II was popular with business users as well as with families and schools, particularly after the release of the first-ever computer spreadsheet, VisiCalc, which initially ran only on the Apple II.
The Apple II had only BASIC built into the ROM. Apple DOS was added to support the diskette drive; the last version was "Apple DOS 3.3". Apple DOS was superseded by ProDOS to support a hierarchical filesystem and larger storage devices. Using a diskette or hard-disk, the Apple II could also load the UCSD Pascal operating system. UCSD binaries are compatible with a large number of other computers, including the IBM-PC. Using a Z80 interface the Apple II could run the popular Wordstar and dBase software under the CP/M operating system.

Anonymous on Tuesday, August 25, 2015 Original "Apple II" came out in June 1977 and "Apple II series" lasted until 1993 with most popular model being "Apple IIe" launched in January 1983 till November 1993, making it Apple's only model with longest production run of ten years. 1984 "Apple IIc" brought a portable Apple II to market and 1986 "Apple IIGS" it's only 16-bit offering. What made original "Apple II" such a success was it featured the key ingredients that would lead to "IBM Personal Computer (PC)" in 1981: Six built-in Expansion Card Slots, (Color) Graphics and a year later 5Â¼-inch Floppy Disk Drive with Disk Operating System (DOS) and killer application on Apple II as "VisiCalc" spreadsheet. Initial "IBM PC" software were direct copies of "Apple II" software in operation and appearance. Due to 'open architecture' approach encouraged by "Apple II reference manual" containing detailed computer hardware information including circuit diagrams helped launch many new hardware industries making cards and software industries writing software. "Apple II+" being a successor would become first Apple computer to be adapted for foreign markets notably "Apple II Europlus" for European and Australian, and "J-Plus" for Japanese markets. Apple first officially licensed clone of "Apple II Europlus" in "ITT 2020" computer for Europe, later Apple would sue unauthorized clone makers, one of the most famous being against "Franklin Computer Corp". "Applesoft Basic" (previously sold separately) came built-in that supported floating-point arithmetic replacing "Integer Basic". With addition of "Apple II Language Card" the computer could be expanded beyond 48Kb motherboard limit to 64Kb, it was also required for "LOGO", "Apple Pascal" and "Fortran 77" ("Pascal" and "Fortran" used non-DOS "UCSD P-System" operating system using its own disk format and ran its own 'virtual machine'). A popular add-on card was "Microsoft's Z80 Soft Card it" featured Z-80 processor making it possible to run "Z-80 CP/M software" or switchback to 6502 for "Apple II software". Easily the best of first generation microcomputers and most advanced that gave rise to PC industry we know today.
Stephen Young on Sunday, July 15, 2012 All I can remember was that, as a technician, I had to un-chip all the DIP's and using a pencil eraser, remove all the oxidation from the pins. Too much heat, already then!
To this day, every time I see an older pc board, I ground myself and re-seat all the chips...
TJ on Saturday, September 17, 2011 I bought an Apple II+ in New York for $1200 in the early 70's, took it back to where I was working in the Middle East, with a 5-day stop over in Spain. Spanish Customs wouldn't let me take it into the country, thinking it was some kind of super spy machine,so had to leave it (packed in a box full of plastic peanuts) at the Custom office. When I went back I opened the box to make sure everything was ok, and 7 thousand electonicaly charged plastic peanuts stuck to everyone in the airport. The Spanish officials gave me 15minutes to clean it all up, but when I approached one young female passenger, meaning only to help her brush her coat, they told me to get out and take the now boxless machine with me. When I got to Customs in my base country (where every foreigner was regarded with suspicion as a spy) I told the Custom official it was a typewriter,and I had no problem. I believe mine was the first Apple to be brought into the country.
