Apple II assembly language

What Hacker News says

   I needed to write screen addressing routines in assembler for the Apple II in 1983. I went to my local bookshop in Sheffield and bought "Apple II Assembly Language by Marvin L. De Jong". This was for my undergrad project and I pretty much have a degree because of that awesome book.

   "Surprisingly, it wasn’t a PC clone-maker that forced the question, but one making Apple II machines."

   There were far more cloners than mentioned in the article. My second computer was a Apple][e clone shipped in parts from South East Asia mixed in a consignment from Rockwell Collins.

   The cost, that magical $2000 dollar mark.

   The parts were re-assembled and that's what I used from High School into my early Uni days until I started using PCs, punchcards and Vt100/Mainframe to learn programming. With a Z80 card, 80 Column card money was made off this machine spitting out resumes via a dot-matrix printer and a large supply of spooled paper. If I remember correctly the shell was a direct clone of the 2e chassis. The operating system was a direct clone. Most of my software was cloned and that's were I learned how to program 6502 machine language to interface with hardware. [0]

   With computers also come books, languages & OS's. My journey goes like this:

   First machine was a Sinclair ZX80 with 1K ram, a bubble keyboard that hooked up the television. No sound, basic for language (using peek/poke for accessing h/w) and tape deck to load programs. Very simple and fun to play with. Hooked ever since. Heres some photos of it ~ http://flickr.com/photos/bootload/tags/sinclair

   - ZX-80->81 | 30 programs for the Sinclair ZX80 1K | Basic | weird Sinclair OS

   - Apple][e clone | Apple II Assembly Language | Apple Basic, Basic, Assembly | AppleDos, CPM

   - IBM clone 8086 | Data Structures using Pascal | Pascal | Dos

   - HP11 calc.

   - IBM clone 486 | C Programming for PC, Learning Perl | C, Perl, Delphi, Fortran M77, SQL | Dos, WIn31, Win95, Linux, Internet - Various Pentium clones | Learning Python, White book, OnLisp, | VB, Asp, Python, Php, Lisp | Linux, OpenBSD, Win2K, Web

   - AMD64 | Phillip & Alexs guide to Web publishing, SEIA | Javascript | Linux, OpenBSD, Web, Internet, Symbian

   - Internet | ??? | Javscript, web api's | Browsers

   Couple of things to note:

   - never really into cars as every $AUD2K I'd spend on new hardware (because s/w I always thought of software as free)

   - always bought clones because the real one items landing in Aus where so incredibly expensive. The best clone story was getting a mate of my dads to take an entire Apple 2e clone from SE Asia in bits because he worked for Collins Radio then watch it be re-assembled.

   - language choice is becoming more interpreted

   - books and operating systems always followed along with hardware so I have a graveyard of both

   - though you might still call it client/server I now consider writing apps for the Internet, web, browser using languages plus markup and data as opposed to just the web only.

   The funny thing is I run a lot of my old systems as virtual machines on my current system.
