PTF, Pedagoško-tehnički fakultet, was supposed to produce the teachers of technical education for high schools, which was a mandatory subject for a few generations and there weren't enough teachers ever - the ones who'd qualify were engineers and bad with pedagogy and mostly working in industry already; the ones available would be the worst students of any kind of engineering or viša and such, or eventually completed the industrial pedagogy in Rijeka, like Radisav and most of the first generation of teachers in MPSŠC. So this was it. For one, Eči finished this. Lidija worked here as an assistant.
For a while in the mid seventies, they hosted the maths division of my faculty - Borko, Duca, Momir studied that. They had only first two years, then for third year they pulled us all together in Novi Sad.
Later, in the late eighties, they started producing the teachers of informatics - like Grgi (who was good and a programmer; most of them wouldn't be able to "code their escape from a wet paper bag", as the expression goes).
The nickname "Petefi" (hun. Petőfi) is, of course, a pun on Petefi Šandor (Petőfi Sándor), one of the main figures in hungarian revolution of 1848.
