update 2025-12-15
I have finally finished a comprehesive hardware analysis of almost every 1980th and early 1990th Casio home keyboard and musical calculator hardware class, including keyboard matrix and IC pinouts. (If you need more tech info or PCB photos, e-mail me.) I also made a detailed analysis of early Medeli (MC-3 variants with DSG or FM sound) and Angeltone (HBATEC) keyboard hardware families. And I analyzed various analogue and squarewave Yamaha (e.g. PS-30, PS-2) and plenty of italo (Bontempi etc.) keyboards and some others. I also added more and better photos and I did a big update of the WarrantyVoid FAQ, the keyboard software media page and some weblinks.

Last but not least I detailedly described the truly bizarre Soviet Russian midi keyboard prototype Arton IK-51 (with PCB photos, IC identification, some history bits etc.). It may seem untactful, but there was no better time for doing so (living vis-à-vis one of their "legitimate millitary targets") before Russia's nukes or jarhead drones will incinerate me.

update 2012-02-04:
Some keyboards removed from my wanted page, because I finally got the ultra-rare MC-55 (FM, similar like GPM MC5000) and Bontempi BS2000 & BS3000 (both strongly resemble BS2010 & KE3860 with same flaws). Sorry, no updates yet.

update 2007-04-12:
I am finally online again on my own webspace. This is only a partial update, thus there may be currently some missing photos and dead links to some pages those are not finished yet. I also have updated the FAQ. Casio SK-5 added.

update 2006-06-07:
Finally a huge new site update has been finished. It contains plenty of new Casio keyboards (including the Super Drums keyboards Casio MT-52, MT-500, MT-520, the Casio PT-50, the squarewave synthesizer Hohner KS 49 midi (Casio HT-700) and the mythical keyboard boombox Casio KX-101 with detailed hardware photos), and I added a big bunch of bizarre new Yongmei tablehooters (with Yongmei YM-2100, DL-2300, YM-3300, YM-6700, MS-110A, MS-210B, Miles MLS-4900A), great My Music Center successors (MIDI synthesizer Elta KE-491, Potex - Super Jam, Yongmei YM-2100) and the great hand gesture controlled toy groovebox Beat Square - AIR-Dance Mixer. Also many new hardware photos, tech infos and corrected Casio chip comparisons have been added and a list of keyboard software media, a wanted- page and a major update of the FAQ.

Note: I will be possibly soon thrown out of the university on which server this site is hosted, thus don't wonder when it disappears. In this case I will try to get webspace elsewhere to install this site again. (Use a search engine.)

Sorry for the long delay.

These include most pre- PCM Casio home keyboard hardware classes and in the FAQ some technical info about their special squarewave synthesis technology.
