This repo chronicles my rediscovery of programming on the Apple //e.

Virtual ][ for Mac is very good and so much better than the half-dozen of the others I tried. Happy to support the developer. Programming in the actual emulator is painful even with the best editors of the day. I find it much better to write in BBedit and copy-paste into Virtual ][.

Personal projects

• TLIFE - Conway's game of LIFE in 100% pure Applesoft with TEXT output
• GLIFE - graphical version of the above
• LIFE - assembly language version... some day
• PETRI - assembly language of my chemotaxis simulator... some later day

Stuff from elsewhere

• BLE2 - BASIC line editor from Compute! magazine, fixed by me

There are several editing programs that I could use. However, maybe it's better to send my virtual disks to someone to make physical copies.

• BASIC
  • BLE2 - BASIC Line Editor 2 - meh
  • EDIT - from Compute! magazine - broken
  • GALE - Global Applesoft Line Editor, looks very good
  • GPLE - Beagle line editor, good
  • Program Writer (Alan Bird) - Beagle full-screen editor
• Machine
  • EDASM - standard full assembler
  • S.S.EDITOR - some kind of assembly editor?
• Text
  • DAK Screen Editor - text editor, not program editor

On the line below 110 above, there is "16 5" in the original work. Is this supposed to be 165 or 16, 5? The code doesn't work in Virtual ][.

Does my //e have a serial interface?
