那是1986年的夏天，21年4个月以前，在诸葛亮抱膝长啸“梁甫吟”、“自比于管仲、乐毅”的地方，第一次看到了有“电脑”这个东西，厚重的屏幕、结实的机箱，还有2个“磁碟机”可以运行各种程序。后来出来很多Apple IIe的缩水版：中华学习机Laser310。Apple BASIC、Apple Logo，还有游戏。
不经意发现了windows上的苹果模拟器
模拟器：applewin 1.14.0beta 主页：http://applewin.berlios.de/
官方资源下载站：ftp://public.asimov.net/pub/apple_II/
工具：自带Apple basic，已经带系统盘
工具：Apple logo II，是logo语言第二版盘，很有趣易学、可以培养逻辑思考能力和几何能力
工具：FishWings，可以在windows下操作苹果磁盘文件(.dsk格式)

| NEW | Erases the current program and clears all variables. | |
| CLEAR | Resets all variables. | |
| LIST | Displays the entire current program. | |
| LIST 11-12 | Displays the lines from 11 to 12. | |
| RUN | Executes the current program. | |
