THE HT-1080Z, HT-2080Z AND HT-3080C COMPUTERS
The HT-1080Z, HT-2080Z and HT-3080C computers were manufactured by Híradástechnika Szövetkezet in Budapest, Hungary from 1983 to 1986. The HT-1080Z was one of the first official school computers in Hungary.
Initial versions were unaltered VideoGenie I computers relabeled and mounted with an on-board Yamaha/General Instruments AY-3-8910 sound chip. (The EACA VideoGenie I was in turn slightly modified clone of the popular TRS-80 Model 1 with Level II BASIC. The Yamaha chip is the same one that appeared in other famous computer models, such as the Amstrad and the Atari ST.)
Later revisions of HT-1080Z were re-designed by Híradástechnika Szövetkezet to have accented Hungarian characters, modified ROM contents (BASIC extensions) and several peripherals.
The basic properties of the most popular HT-1080Z models are summarized here:

The HT-2080Z machines had the same specifications as the 1080Z models, but they were positioned as business computers instead of school computers.

The 3080C model was available in prototype form only. It was designed in response to a call for a tender to prepare the second generation of school computers in Hungary. Its main characteristics were as follows: high resolution graphics (256x192 pixels, 8 colors), RGB output, Centronics interface, function keys, full support of Hungarian accented keys, and emulation of Sinclair ZX Spectrum BASIC programs.

BASIC programs are available to dowload here, while SYSTEM (machine language) programs are available here. Note that a large number of programs is available at TRS-80 sites, thus only Hungarian programs (and programs that were wide-spread in Hungarian schools at that time) are stored in this site.
