Scelbi/8008 OS/X Emulator Updated

Several serious bugs resolved including:

  • A problem with the 8008 subtract instruction that didn’t correct set the carry bit. This prevented Scebal Basic programs from being larger than 256 bytes.
  • Several problems with serial input/output that could cause pasted or typed input and/or output from behaving correctly
  • Max paste buffer size was increased to 4k bytes, in order to allow pasting of complete or at least large portions of BASIC programs directly into the emulator
  • For instructions and download links see my previous post:http://www.willegal.net/blog/?p=1705

    For fun, try booting up Scebal and running this program:http://99-bottles-of-beer.net/language-scelbal-2472.html

    I’ve also been working on the per cycle emulator so that I can make the emulated toggle switches and leds work correctly.
