Hi, my name is Jonah Cohen. I'm currently a sophomore attending Harvey Mudd College in Claremont, California, with interests ranging from TI calculators and computers to such things as the Mercedes S600. You can also just find out more information about me on the about page. Oh, and while you're here, be sure to sign my guestbook!

Megacar is currently being promoted on TI's education website. I think they meant to link to the TI-83+ version rather than the TI-86 one, but that doesn't mean I can't enjoy in the fact that Megacar is the #1 downloaded program this week on ticalc.org, right? |

I made a few more modifications to cz80, mainly to correct some eccentricities in the expression parsing. New version is in the cz80 directory as always. |

There had been a bug in cz80's preprocessor code for as long as I could remember, but I never got around to fixing it. Turns out it only involved changing a single line of code(!) So anyways, users of cz80 can get a new version here. |

I just changed the license agreement on the pclasses from GNU General Public License to GNU Lesser General Public License. Now they can be used in closed-source programs as long as the pclasses source files (and any modifications directly to them) are included in the distribution. |

Paul Marks has released a port of my TI-86 game Megacar as a TI-83+ flash application. You can download his version from ticalc.org or go visit his TI page for more info. |

Decimal Defender is out! |

I just uploaded a new version of my dos-based z80 compiler, cz80, which can be found in the cz80 directory. The main new feature is that it now has order of operation in the arithmetic parser, so 3+2*4 is 11 rather than 20. For those of you who'd rather use your own personal favorite editor rather than being stuck with an IDE, this should give you even greater coding flexibility. Let me know if you have any comments. |

Minor updates to iShell can be found in version 2.01. It no longer freezes when returning from Bill Nagel's Mario or Chris Tremblay's Lemmingz, and it also doesn't detect the basic loader program IShell anymore. If you have any other suggestions for improvements to iShell, please email me. |

iShell 2.0 is out! In addition to a recalibrated battery meter and other tweaks, the biggest update in 2.0 is that you no longer have to keep scores of little files floating around on your calculator -- it is now a standalone shell! Check out Aaron's site for more information about development for Yet Another Shell. |

For those of you that don't know, I've been working on a new game for Texas Instruments that will be distributed as a free application for the TI-83+ and TI-83+ SE. Hence the secrecy :-) Aaron has been working rather diligently on finishing up a new version of YAS, so you can expect that to be released sometime in the near future. Check out Aaron's site for more details. Also, I updated my desktop screenshot on the computer page since the previous one was nearly two years old. |

College is fun. My email address is now jcohen@hmc.edu. Please don't use my AOL account anymore. |

Well, the summer has been rather busy. Today is my last day at work, and then I go on vacation for a week right before I head off to college. For anybody interested in prom photos, I've uploaded them to a directory here, though they're not particularly organized in any way... Also, for those curious about what sort of development environment I've been using for programming TI calculators (no, I haven't forgotten about them; I just haven't gotten around to updating the website), my current configuration uses Ultraedit for coding purposes and cz80, my own modified DOS assembler based on Assembly Studio 8x, for compiling code. You can check out the related files in the cz80 directory. Note that this is completely unsupported! If you want to use it, do so at your own risk. |
