TI Cpu based computers:

  • CDC 99/4A
  • Tomy Tutor
  • Tomy Tutor Mark II
  • Tomy Tutor Junior

As this website was started in 2016, please be patient with me to get all information up.

My name is Klaus Lukaschek. I was born in 1980 in Vienna, Austria, when the TI-99/4 was already released. I got in contact with the TI-99/4A computer in 1983. Since that the machine fascinates me, it further set my profession. I am working as .net Web Developer in the IT industry.

In 2011 my brother and me refounded the Austrian TI-99 Usergroup as there was no activity in Austria back then.

    Good luck with this great project. If there is anything from my collection you would like photographed, please let me know.

    Glad to hear that you’ll be at Birkenau. I might take a drive down there myself to have a chat with you about ways to produce definitive rarity lists for software (in all formats), hardware and Literature.

    Very best regards

    I like the site. You can also add a couple of additional machines with TI CPUs to your list: Powertran Cortex, Powertran Cortex II, and Marinchip S9900. The Cortex BASIC that Stuart ported over came from these. . .and the Marinchip’s claim to fame is that it was designed as the host machine for the earliest version of AUTOCAD. It was also the machine that was used to develop/port a lot of software to the Cortex (mainly from the TI990 software library).

    The TI99/4a was my very first home computer. Back in those days infomation and money was an issue. Today it’s time ๐Ÿ™‚
    I’m really happy to find sites like yours, so I know I’m not the only one dealing with such vintage things.
    Please keep your site up. I’m also thinking about dedicate a corner for the TI-stuff on my blog. Maybe I start with documenting my experiences with the brand new FinalGROM99 from Ralph Benzinger. It’s just great, we have 2017 and brand new gadgets are still released for the TI99/4a.
