HERE IS STORY ABOUT PEOPLE WHO MAKE IT.

IRIS 8 - Računar proizveden u BiH

OVDJE JE PRIČA O LJUDIMA KOJI SU TO STVORILI.

Branislav Stupar is a designer and he made IRIS 8, in fact, his company SPE Electronic Sarajevo. Here is part of the pictures of which are preserved, most of the documents destroyed in the war even though SPE ELECTRONIC work all the time the war (my brother was disabled and released from military service) and company is closed in 1999.

IRIS 8 is based on Apple II computers. At that time it was forbidden to import computers in Yugoslavia so we were clever and smart. It was a goal that children have to learn what, then they learned programming languages without computers it was ordinary nonsense.

The computer is made by team of people as follow: Stupar Branislav, Andreja Markovic (then student, now in Australia), my brother, Mladen Stupar (died 2004), my brother Joe (Dr. Milorad Stupar, Dept. Of Astronomy, University of Sidney), Rudolf Bosnjak (in Sarajevo is engaged in electric cars), and Edin Grapcanovic (in Sarajevo, was employed by us).

Great help and support we have received of Energoinvest Institute for computer systems (IRIS), Marko Zirojevic director of IRIS, Zoran Salcic my classmate and then Dean of the Faculty of Electrical Engineering Sarajevo, now Profesor. University of Auckland and Nebojsa Rajacic, Head of Customer Support IRIS (died 1992) and many others including and Dragutin Braco Kosovac, president of the Steering Board Energoinvest.

Branislav Stupar je idejni tvorac i on je napravio IRIS 8, ustvari njegova firma SPE Electronic u Sarajevu.. Ovdje je dio slika o tom radu, koje su sačuvane, većina dokumenata je u ratu uništena iako je firma SPE ELECTRONIC radila cijelo vrijeme rata (moj brat je bio invalid i oslodjen vojne obaveze) i firma je zatvorena je 1999.

IRIS 8 je baziran na APPLE II računaru. U to doba je bilo zabranjeno uvoziti računare u Jugosaviju pa smo se mi dovijali. Bio je cilj da se djeca imaju na čemu učiti, tada su učili programske jezike bez računara što je bila ordinarna glupost.

Taj računar smo napravili ja Stupar Branislav, Andreja Marković (tada student, sada u Australiji), moj brat Mladen Stupar (umro 2004), moj brat Joe (Dr. Milorad Stupar, Dept. of Astronomy, University of Sidney), Rudolf Bosnjak (u Sarajevu, bavi se elektro automobilima), i Edin Grapčanović (u Sarajevu, bio zaposlen kod nas).

Veliku pomoć i podršku smo dobili of Energoinvest Institut za Računarske Sisteme (IRIS), Marko Zirojević direktor IRIS, Zoran Salčić moj školski drug i tada Dekan Elektrotehničkog Fakulteta Sarajevo, sada prof. University of Auckland i Nebojša Rajačić, Šef Customer Support IRIS (umro 1992) i mnogi drugi uključujići i Dragutin Braco Kosovac, predsjednik Upravnog Odobora Energoinvest.

PROCESSOR

IRIS-8 was carried around the 8-bit 6502 microprocessor and the system clock 1MHz. On the processor board is located 12 Mb ROM and 64 Mb of RAM. Because of its "open" architecture, it is possible to add specific modules and other microprocessors such as Z80.

PERIPHERAL MEMORY

To work with larger data volumes, IRIS-8 has one or two disk unit 5''1 / 4 capacity of 630 Kb. Optionally, you can add 1 or 2 fixed (Winchester) disk drive capacity of 10 Mb.

KEYBOARD

The keyboard is a serial type, with the standard ASCII set of characters separated by functional and the numerical part. Has 84 programmable keys so that, except ASCII character sets, can help a special program that recognizes and YU set of characters.

MONITOR

Monitor, which comes standard with the computer IRIS-8, the monochrome, green, screen size 12''CRT with high resolution. It is possible to print 40 characters in 24 lines or 80 characters, using a special module. For the specific purpose or at the request of users, can be delivered and color monitor.

PRINTER

With the use of serial module output, we used dot-matrix printer speed of 120 cps. In NLQ mode printer can be used to print business letters and other similar documents.

PROGRAM SUPPORT

Basic operating system computers IRIS-8 is a DOS 3.3, and additionally with CP / M and Pascal. IRIS-8 works with programming languages ??BASIC, FORTRAN, PASCAL, LOGO, FOTH. Due to this the number of available programs is quite large.
