Desktop (word processor)
Desktop is a WYSIWYG word processor for computers Sinclair ZX Spectrum and compatible (e. g. Didaktik). It is a word processor of Czech origin, its author is Tomáš Vilím who used the name Universum as his author name. Distributor of the program was Proxima - Software.

Destop is very advanced word processor when compared with other ZX Spectrum word processors, it uses proportional fonts and it can use four different font in one document. However, it is not possible to use bold and italics variant, every variant needs to use independent font.

Program was distributed with three supporting programs:
 Convertor - converter of text created in Tasword, D-Text, R-Text, D-Writer, and Textmachine into Desktop format,
 Fonteditor - for editing fonts and writing headings, it can covert color images into gray scale images,
 Screen Top - for editing images up to dimensions of 512 by 384 pixels (2 by 2 screens of ZX Spectrum).

Several printers and plotters were supported for printing the text:
 plotter Minigraf Aritma 0507,
 plotters XY 4140, XY 4150, XY 4160,
 plotter Merkur Alfi,
 1-pin dot matrix printer BT100,
 printer Gamacentrum 01,
 thermoprinter Robotron K6304,
 9-pin dot matrix printers Epson FX, RX, LX, EX and compatible,
 24-pin dot matrix printers Epson LQ and compatible.

The driver Ultra LQ was developed for better printing at Epson compatible printers, it prints the letters in the matrix of 16 by 24 points instead of original 8 by 12 points. The driver Ultra BT for better printing at BT100 printer existed too. These drivers were distributed as independent software packages.

Special version of Desktop with driver of D-100 printer existed, because D-100 was not compatible with Epson printers. Also a version supporting PRT 42G printer existed.

Four sets of supporting programs, drivers, fonts, images were developed and distributed under the names Klub uživatelů Desktopu 1 - 4 (in English Desktop user club 1 - 4).
