Hello Jeff, Just found your name on the internet and am trying to figure out where our family relations start. My son is Hessel and had contact with Christina Day who sent a book about the Canadian connection which I received today. Very interesting. Regards,

Hey Jeff how's it going? Remember your senior design group member Phillip? I'm in Texas working for L-3 Communications and I am signed up to start my master's at Purdue via their distance program. I was looking through the list of students to see if I still knew somebody... Anyways digital gnomes rock! Adios, Phil

Uncle Dave | Website | March 18, 2007, 5:31 pm

Hey Nice website. But I would like to know how I get the programs to read on my computer because I have no cable to download direct to my ti 85. If its possible tell me how to type them. Yes I have all that time.

cheikna | Website | March 16, 2007, 12:06 am

hi,jeff--glad to see and hear of you doing so well,but i knew you would a long time ago.stay strong,love to you and sarah.if you'd like,email me,if not that's ok guys are always in my heart...

jane bergren from fremont | Website | March 11, 2007, 8:03 pm

Check out the FAQ for a response!

Jeff Turkstra is an ass. I have legitimate questions regarding programs for my TI-89 and his FAQ page just rambles on about nonsense and how he stuck it to some poor high school kid for borrowing some info from the internet to pass a class that we all know will mean jack shit to his life and career. Plagiarize this Jeff..."You're a tool."

Jeff Reinert from wisconsin | Website | February 23, 2007, 1:17 pm

Hello all you!

Ulipy | Website | January 25, 2007, 3:14 pm

Hey Jeff! You're going to have to tell me how to get those TI-86 games to download to my calculator. I'm new to this, so please help me. Use my e-mail address to contact me, I check it every day. Thanks

Ray from WA USA | Website | January 30, 2003, 6:25 pm

Well, Jeff. Congrats to you and your site. It's even bookmarked in a coffee shop computer in Europe. Hurrah for you. Keep up the good work. Oh. and when Phil surpasses my lines, i'll be back to clame third place. Till later. Give my regards to Cai. ^~

Jack from USA | Website | December 9, 2002, 11:29 pm

Nice Site.. Thanks for the TI-86 programs and the great MIDI's.. Do you have any recordings of the Purdue Marching Band? If so, I'd like to hear some of the music. Thanks.

Loren Waddle from Eugene, OR USA | Website | December 4, 2002, 4:39 am

Keep up the good work with the programs for the TI-86. It is getting increasingly difficult to find good programs

PD Williams from Detroit, MI USA | Website | November 21, 2002, 6:22 pm

You made a great site those programs are actually really useful in my chem and physics class. Thank you :). Keep up the site for other ppl. They would want it.

You definitely dont know me from USA | Website | October 26, 2002, 12:02 am

Hello, it's Wednesday and I come back from Berlin. I find your Site bookmarked in a Internet Cafe. I have closed more time explained around me with the contents of your home page from each other now. Unfortunately, there are little good sites. Your site is very good. I will recommend and come back. V.B.

Hey, Jeff. I love you puppy!! but i swear, you eat the strangest things at you computer. and maybe, MAYBE i'll come onto your server again. but, of course, that means yes. Talk to you later, Jeff. Love your smile, btw.

Bekah from asif, TX USA | Website | July 2, 2002, 3:29 am

Nice job :-)

Insider-X from Zoetermer, - Holland | Website | July 1, 2002, 1:18 pm

Excellent site! But if I must be critical...some of the chemistry stuff you have is not very useful. I studied for the AP Chemistry test this year and the stuff you are calculating is for the most part simple math that can be done on a scientific calculator. I would love to see something that calculated the units of and value of the constant k in a rate equation (in the subject of chemical kinetics) Keep up the good work.

David Pedack from Seattle, WA USA | Website | May 22, 2002, 12:22 am

Hey, great website!

I don't know if you remember me or not, but I was trumpet and marching instructor at Grand Haven High School band camps (those weeks up at the ski lodge in Petosky) for the summers of 1997 and 1998. You might remember me clowning around with the other counselors, especially: Wes Broadnaux (trombone, 97) and Scott Roeder (tuba, 98). I miss those days, as well as Mr. Ernes and Mr. B. Do you have email addresses for any of those folks, or any of the students from your class?

Just thought I'd drop a line to say howdy and keep up the good work!

Ken Wallace from Chicago, IL USA | Website | May 5, 2002, 6:04 am

Hi Jeff,
here a sign from someone of your HOMELAND: Holland, that's where your and our ancestors are from.
We are originally from Friesland , a province in the north of Holland, I ave a lot of family living there,

You must have end up in the US by some of the people from Holland who have emigrated to the USA. Most probably farmers..... do you know,

Good luck with your sites and if you want more info pls let me know.
bye Luuc Turkstra
(currently living in Paris, France)

Luuc Turkstra from paris, france | Website | October 5, 2001, 1:17 pm

I absolutely love ur site. there are a few suggestions though. Get more trigonometry and algebra programs like factoring functions or solving functions. I also think u need alot more games for not just 86 and 89 but also 82, 83, and 92. I'm willing to help so contact me anytime.

Levi from Houston, TX USA | Website | August 30, 2001, 10:58 pm

I like this website a lot because it makes me happy. Please send me email.

Scott Webb from Tustin, WI USA | Website | May 29, 2001, 6:08 pm

Hey! Get job on the site. I am, like, in love with the show seaQuest. I was wondering if you have a little more info for me. I'm trying to find out when the show(both DSV and 2032) aired and when it stopped airing. I'm also trying to find out what the actors have done since then. Any help would be greatly appreciated. Thanx and keep up the great work!
