So at first, Kompakt don''t use MSDOS formated disks, but use it''s own format and 720kB per disk. It can''t handle HD diskettes. Memory extension was not provided by Didaktik and PCB was not prepared for it. AY can be connected externaly (Didaktik Melodik). Video can be connected to TV output, composite output or scart. Colour pallete is the same as ZX Spectrum, no extensions. And no CP/M mode. - author: wilsonsamm (Off the western coast of Norway) date: Wednesday 15th October 2003 text: |- Actually, the Didaktik Kompakt is still available.\ sintech.de sells them now. related: - /museum/didaktik-gama - /museum/didaktik-m - /museum/microdigital-tk-90x - /museum/microdigital-tk-95 - /museum/robik - /museum/spica-ines oc_id: 953 source: url: https://web.archive.org/web/20230609174624/http://www.old-computers.com/museum/computer.asp?c=953 date: '2023-06-09' --- The Didaktik Kompakt was the last model made by Didaktik Skalica. The Didaktik Kompakt is a [Didaktik M](/museum/didaktik-m/) with a built-in 3.5" disk drive(720 KB). It has standard connectors for joysticks and printer and a built-in parallel interface using i8255 as in [Didaktik Gama](/museum/didaktik-gama/). The amount of internal ROM was doubled, 16 KB for the [Spectrum](/museum/sinclair-zx-spectrum/) BASIC interpreter and 16 KB for the MDOS operating system. All other features are the same as [Didaktik M](/museum/didaktik-m/). It was a real all-in-one computer with built-in power supply unit. Base model had 48 KB of RAM, expandable up to 128 KB (not provided by Didaktik). Sound output was a poor beeper. An AY 3-8912 sound shipset (3 voice, 8 octave + white noise generator) could be connected externaly via the Didaktik Melodik expansion. Normal TV set could be used as well as EGA monitor. ULA custom chip was the same as the M version, screen was thus still square. The interesting thing for computer collectors is you can still buy a didaktik model along with all its accessories and expansions.
