Momentarily I'm working at 2 schools and maintaining three informatics classrooms and computers in the other classrooms.
When I was working in four schools in the same time, in addition to teaching 4 multiseat (Multipoint) systems (105 workstations with 11 computers + 4 teacher's PC) and more than 60 other computers were maintained by me!

Dózsa György Primary School
My first job as a teacher. The colleagues were helpful, making it easier to successfully reorganize. I can tell you that this is almost a full relaxation compared to recent years. The children's world is completely different from the adult world and it's good to be in it. As regards the curriculum - it should be taught that I was doing many years. Of course there is always progress, but the previous IT experience helped a lot. I liked the ting so mach that I enrolled in the IT University (informatics-teacher course) and I finished in 3 years. To the technical stuff was added a little psychology, pedagogy, didactics, methodology, ...

doo Zanatstvo
This was one of the successors of 1.Maj. I worked here in a half-time for nearly a year. It isn't left a really deep impression on me. I remember only the constant noise and the smoke of cigarette. Today, there are only a few remainders of that firm ...
I sat at the opening, which was window in the past. Since this room once belonged to Automatic Data Processing (previous work), I am binded here with a double nostalgia.
doo "FMPE"
This was 1.Maj's another successor. I worked here a half-time of almost 5 years. In the beginning, the company's cart went well, but then here came the downturn, rom which it never came out - it's ended up in bankruptcy. Relatively good company came together, because some of use were retapriated from the previous workplace. We have worked, sometimes the banter is gone.
A little work ...
1.Maj Construction Company
My first job, where I remained a long time, and certainly made the grade in all stages of the department from trainee to the head. How did I get here? Well, so that people were looking for construction graduates. Two of them appeared, and admitted both of us, thus began my career in IT. It was not difficult learning process because an excellent team of professionals paved my way - the colleagues were excellent. Thus, almost pulled each other in progress. I still think with the nostalgia about that company for almost exclusively young people.

Let's see what kind of machines we had!
Not the original image, but the same machine (Honeywell Bull DPS-6 GCOS 6 MOD 400). On the left side is the central processing unit with "a lot" of memory (maybe 512 KB or 1 MB, I can not remember), beside it is a tape unit for backup purposes (our first task in the morning). Two disk units are located to the right, both of them with a  "tremendous" capacity of 300 MB hard drive, which can never fill up. (We succeeded!). On the top of the farther is a "cake-box" for the hard disk - that is, they were cca. 40 cm in diameter! (The tape unit also has one on its top). Moving to the right you can see one tape-stand. So they are not an audio-cassette tapes in size! On the the right end there is a line printer. Noisy and fast printing - it was capable to "spit" a full box of A4 banner (an endless, at the edge perforated paper) in an hour.
This is a typical image (also not original). On the left is a Tape Unit. You can see that it was a large, nearly empty cupboard, with a couple of electronic cards, mechanics, etc. A bottle of fine brandy stands excellently in the lower part. To the right are papers for printing, they are followed by an iron locker, because the tapes had to be protected. There are teminals on the right with keyboards on their tops.
The type of the terminals was VIP7300 and somehow it was like the one above were located during work. Please ignore the lack of cables, since it is the original device out of order. In functional state we kept in touch with them to the central unit, ie, the commands are issued through it and we wrote our programs too. The screen had a diameter of 12 inches, if I remember correctly. "Low Radiation" logo wasn't anywhere!

I say only for today's young people that we were working in text mode, so that each command was typed into the terminal. On these terminals the characters appeared in green on a black background. Here's a little taste of the operating system commands from the 400-page users guide:

List of all commands
PRINT command

So what we had to keep in mind!

Later we used to work with more "user friendly" HDS-5 terminals.
In the new design orange characters appeared on the black background! Unfortunately there is no screenshot.
Close up of a central unit. 5.25-inch floppy, and switch.
The Central Unit and the Tape Unit were filled with similar boards. On the left there is a pencil just for detecting the proportion!
Let's see what sort of programs we wrote! Simply said, all kinds. We wrote to the company all the necessary accounting and production-following programs (except financial). There was everything from a payment through the norms to the warehouse. It was good high school to find the solutions.

I personally have used the following programming languages:
Basic (little)
Fortran (little)
Cobol (a lot -  98% of the company's programs was written in this)
Clipper (medium)
Clarion (little - more later)
Programming process
Here, we disregard such things as the problem-analysis, gathering documentation, planning, testing, etc.. I'm dealing with the programming process only.

Typing the program into the computer trough the terminal

There were two ways to achieve this:

Line Editor

ED -PT was the command used to starting the editor, upon what this is appeared on the screen:

EDIT 3.0-08/06-0713

A question mark was the sign, that the editor is waiting for further commands. This usually meant reading some files into the editor, like this one below, which is reading file named szoveg.

E? R szoveg

We listed the contents of the buffer onto the screen with this command:

E? 1,$ !P

There was a time for editing. This command below deleted line 18:

E? 18D

After the appropriate editing (which was MUCH MORE COMPLICATED than this one above) came to save the changes...

E? W szoveg

...and then exit the editor:

E? Q


RDY: was the ready prompt of the operating system.

We get it already, right? All you had to manually type the command into the editor's command line! Total torture! Unfortunately it was not yet a mouse with a graphical operating system!

Scorpeo (Screen Editor)

This was more user-friendly and it was very similar to the DOS world's text editor. Editing was very flexible - he knew everything about what today's simple text editor. Unfortunately, no pictures of it.

Compiling and linking

This was done with the EC (execution) files, which are functionally identical to those of the DOS bat (batch) files. Here's an example:

&P cobola-link - bez kopiranja u TCL i PROGS , za MAT10
&L L1
>SYSLIB2>COBOLA &1 &2 &3 &4 &5 &6 &7 &8
&G L1
&L P1
&L L2
&L L3

If the program hadn't a formal defect, the machine code was built and the program was ready for running. Of course, this did not mean that it worked right!

A legend was born: two of my colleagues (Szilágyi Róbert and Mester Károly) wrote a perfect program without a GO TO command, using only the PERFORM command (structured programming). Here is the source code of the program MAT10.C.

My personal contribution to this program was MAT62.F, which happens to be written in Fortran and ran from MAT10.C (see MAT10.C source code at the very end).
PC (Personal Computer)
In 1989 in the company also appeared the first personal computer (PC). They had the following modest technical specifications:
80286 processor, 12 MHz
40 MB hard disk
Hercules Graphics Card (monochrome)
up to 1MB of memory
They looked something like this. Of course with MS-DOS operating system, beside which slowly and shyly appeared Windows as well in version 3.1.

We worked in an network from 5-6 machines, which had one server with a very well executed Novell Netware 3.11 operating system. That's a different story, that Novell was not recognized in time for the deployment of graphical operating systems announced by the "new times" and it is because they lost a big slice of the server market share. If you want to know more about this visit here, but I prefer to talk  to about something else: about NSNIPES, which was Novell's network-test program and a game in the same time.
It's place is in the informatics-museum, because it was popular in the early nineties.
Well, it looks like this. Do you remember? We loved this game because at that time it was the peak of games! We played in the network against those little "creatures" born form that squares on the screen and they were shooting at us constantly. Of course we were shoting too. When they all were killed we turned against each other in the labyrinth. Deathmatch!

Here is a little "live" preview of it:
PC games
The PCs-games brought completely new colors in our lives: Prince Of Persia , Defender Of The Crown, Eagles Nest, Street Rod, etc.. Those were the games where in a few clicks you could play, even without any preliminary study. The weakness of the graphics was compensated by our imagination. (If you want to play today's games, then you have to study quite huge manuals for a days to achieve a simple goal in the game.)

This one below belongs to the Eagles Nest game.
Each floor had to be cleaned from the enemy, and to free the hostages. To help the lonely hero the ammunition, first aid kit and cold food is placed in a many places. Despite its simplicity it could be well played. So much so that once i passed a score 999,999 and since there was no place to display a greater number, the numbers were randomly rolling after that!

My another favorit was the game Street Rod.
With the worst car at the beginning we have to win many street- or outside-city tournaments to gain more money and better cars. The price could be even the opponents car! At the end we had to beat the King, how is the coolest man in the city and owns the best car. The car in the garage could also be fitted! Transmission, carburetor, engine, etc. replacement, bumper decommissioning was always good way to win a little extra speed.
Honeywell's end
In the Winter of 1996-97 Honeywell gave up his spirit: the frozen radiators on the floor melted out and ruined all the techniques! The information system was completely broken. The situation is solved with buying some of new PC-s and software. This was the end of my Honeywell's era and the beginning of my PC epoch.

The progress is accelerated, the PCs become more common, operating systems changed each other - Windows 95, Windows 98, Windows NT, Windows 2000, Windows XP ...

The company began to turn hedge-hopping, more and more people left the company, the above-mentioned company has disappeared - only I was left from  the old team. Some new people came to the department, but the old light has never shone.

After a few years of agony the company fell apart components. So I got a half-a-half hours of work in two firm-successors - but that's another chapter.

The Automatic Data Processing Division has been slowly decayed. There is nothing left to see, but the ruins below (the original recordings!). Sic transit gloria mundi. Thus passes the glory of the world.
