I also worked on Lurnix's C++ tutorial, and their A/UX tutorial for Apple. Very partial list of things written, done, and worked on before Macintosh:

• Editor/Assembler, Linker/Loader, Disassembler/Debugger, DOS

• Device drivers: serial, parallel, terminal, printer, hard disk, floppy, tape, voice synthesizer...

• Interrupt driven real-time system; multiple screen/user system

• Text/data compressors/expanders; data filters/massagers/loggers

• Menu systems, table/forms/template definers; macro processors

• DB: input/sort/shuffle/merge/Format-output; data content/format verifiers

• Source level C-Debugger; 3D blocks world; color screen editor

• Games: wrote/ported, master/slaves; communication protocols

• Enhanced and ported the "Small C-compiler", BASIC compiler; interpreters...

• Pretty Printer/XRef/CFlow Indexer...

• Ported C-code between OS/machines/compilers; DOS UNIX using Standard C Library

• Converted between Assembly and C, and Pascal and C

• Optimized for: speed/size XOR readability, clarity, portability, maintainability, re- usability, supportability.

• Lead/support programmer; librarian/archivist.

• Was hardware/firmware competent. Favorite assembly language instruction: XOR.

• Best mini hack: I keyed in the hex of a disassembler and had it disassemble itself. I collect good source code libraries, both commercial and open source -- especially BSD licensed. At last count I had over 6000 open source iOS code projects to glean from. This usually saves weeks of time on any project.
