This mini forum is intended to provide a simple means of discussion about the I.S.T.C. (Informatic Systèmes Télécom) 5000 computer. If you want to share your own experience or memories, or add relevant information about this system: post a message!

I used to have one of these, it was a horrible computer because of the weight.

Just reading the Advertisements from this funny thing and comparing with your datasheets:

In Octobre 1979 this machine did cost 28.700F, not the 36.000F you have in the Technical Information

(The advertisement from Jan 1980 gives reference to the price from Octobre 1979)

The Disk drives in the 5000 model are described as 300Kbyte disk drives, the one in the 5500 model as 2MBytes Disk drives, also containing a 20 Mbyte hdd

so actually it had not only better disk drives, but also a harddisc

Sadly there is no other information to gather from them, and i personally was 3 years old when they came out - so i cannot say much about them from my own experience, just translated the ads
