It was a stroke of luck\u2014while browsing eBay, I stumbled upon the VTech IQ TV 512. It is a truly peculiar system from 1998. VTech (Video Technology Ltd.) is an electronics company founded in Hong Kong in 1976 that still manufactures cordless phones, simple computer systems, and electronic educational toys for children today.<\/p>\n\n\n\n

There are two models of the device\u2014the IQ 128 and the IQ TV 512\u2014which differ essentially only in their RAM capacity (256 KB and 512 KB, respectively) and their boot screens. They are powered by the Motorola MC68EC000 processor\u2014a lower-cost variant of the MC68000 lacking a memory management unit, similar to the chips used in the Commodore Amiga and Atari ST. In the IQ TV 512, it is integrated as a custom chip and runs at 16 MHz<\/strong>. The computer was also released in England, France, and the USA under different names: \"I.T. Unlimited\" in Great Britain, \"Genius PC\" in France, and \"PreComputer Unlimited\" in the USA.<\/p>\n\n\n\n\n\n\n\n

It features a resolution of 512 \u00d7 256 pixels and a 256-color palette, with sampled sound output available via the audio port. The TV 512 is classified primarily as an educational computer; unlike many others in this category at the time, it lacked a small built-in LCD screen and instead connected directly to a television. It features a full-sized QWERTZ typewriter-style keyboard and a three-button mouse. I once read in an old Austrian article that its retail price in 1998 ranged from 3,000 to 5,000 schillings\u2014equivalent to roughly 430 to 720 DM<\/strong> at the time, or approximately 220 to 370 euros today.<\/p>\n\n\n\n

    It does not feature a standard removable storage drive. The device itself provides 512 KB of RAM and 128 KB of flash memory for the permanent storage of user data. Additionally, external memory modules can be inserted via the expansion slot. According to contemporary reports, the original package included two such modules labeled \"IQ 128 Super Speicher\"\u2014an indication that VTech did not release dedicated accessories for the TV 512 but instead reused those from its predecessor. Unfortunately, these modules were missing from my unit. A file manager allows for copying or deleting files between the internal flash memory and the external module.<\/p>\n\n\n\n

    The most important aspect of the software features is the set of programs integrated into the ROM, which are launched via an interface called \"Schreibtisch\" (Desktop) that is reminiscent of Windows 3.1. These include several games, an organizer, educational software, and office applications. Here is an overview of some of them:<\/p>\n\n\n\n

      Incidentally, the TV 512 is considered to be arguably the last microcomputer of its kind programmable in BASIC\u2014a minor historical curiosity. For those interested in emulation: the device runs fully within the MAME emulator under the filename iqtv512.zip<\/code>.<\/p>\n\n\n\n

      Conclusion<\/h5>\n\n\n\n

      An interesting device that actually works quite well. I do miss the ability to connect a cassette recorder or a floppy drive. While the software is simple and intuitive to use, it is really on the level of programs common on Windows and the Amiga back in 1990. Performance isn't exactly impressive; there is sometimes a lag when pressing keys or clicking the mouse. If anyone happens to have a spare manual and an external storage drive for the unit, I\u2019d love to take them off your hands to complete my setup \ud83d\ude09<\/p>","protected":false},"excerpt":{"rendered":"
