Mainframes are nice! Unfortunately, I don't know much about the four-digit codes of IBM, so I cannot tell you what exactly is in the pictures by saying: "well, this is a 3380, that over there is a 4230 and that big one is a xxxx". Who can memorize these numbers? Anyway, these are just big blue boxes :-)

These pictures were taken at a 4381 installation. The machine is retired now, but it still in the machine room. This is a /370 system and it sure looks like what a real machine should look like ;-)

The box behind the chair is a 4381 processor
... which is not exactly a micro-processor :-)
BASF removable-disk hard drives
Hard disk platters (from a 3380 or so)
A very nice-looking magtape-drive

The machine depicted below was the first computer in Hungary with an Internet-link. Sadly, it was discarded, the pictures were made on its last week it was up.

The machine on the last series is still in service at the Technical University of Budapest, but since it's to expensive to maintain it, it propably will be retired soon too. It seems ther will be no real mahcines in the country... Just like the pervious one, this was a 3090 system, but the TUB has acquired a new processor for the system, an ES/9000.

And now for something completly different: terminals!
And for those who don't like terminals: terminals!
