For the interested reader:

I received today the two TI-88's - they were manufactured in April (left) and May 1982. You might notice a few differences with the keyboard lettering:

The calculator software speaks three languages: English, German and French:

The calculator is not Y2K compliant, it insists to set the Day of Week today, January 9th, 2012 (a Monday on my calendar) on Sunday:

So long,

Thanks for sharing these details and the nice pictures of one of the rarest calculators. You may be able also to take a picture of 3 TI-88 side-by-side which could set a record for many years (or centuries...) to come


If you attend any HHC conference in the futures (and I sure hope you do), please please please bring at least one of these TI-88 calculators with you. It would be nice to see how they are programmed.

Quote from the site linked by Gerson:

"Date and time, you ask? Yes, the TI-88 has a built-in clock and calendar. For the curious: the TI-88 is Y2K compatible. Interestingly, it contains no perpetual calendar that would allow it to compute the day of the week automatically; instead, it must be entered, in addition to the date."

Perhaps there is a workaround to choose the day of the week.

Today in Dallas, TX:

"I'll file a defect report about the Y2K issue tomorrow, although I doubt a software fix will be forthcoming."

I'll keep ypu posted.


For the record...



I will and I will ;-))
I planned for 2011 but had to be in Las Vegas (Pack Expo) to setup a product that we developed for an Australian based customer.


It would be nice to see how they are programmed.

You can find more information on programming including a sample program written by Maurice Swinnen in V7N7/8 and V7N9 of TI PPC Notes which are available at Viktor's site.

At one time I had a draft copy of the manual. I think I gave it to Gene Wright but I admit that my memory plays tricks on me these days. If Gene tells me that he doesn't have it I will search my files.
