Casio MT-41
A Casiotone that turns up in dealer ads more often than in the spec sheets, and nobody wrote down what was inside.
Overview
Casio's Casiotone line produced a long run of small, cheap electronic keyboards, and the MT-41 is one of the ones the paper trail mostly forgot. The name itself comes down to us in two forms — "Casio Casiotone MT 41" and "Casio MT41" — both appearing in the same surviving source, which describes it only as a "Vintage Electronic Keyboard." That's the honest extent of the documentary record here. There is no key count, no voice list, no rhythm section detail, no dimensions, no weight, no power spec, and no circuit description to be found in the material that has surfaced.
What the period trade press does preserve is the price. British dealer listings — the kind of dense, all-caps mail-order spreads that filled the back pages of the music magazines — show the MT-41 sitting near the bottom of the Casiotone range. One London-area retailer advertised it at £79, with free carriage on all Casios, alongside the MT-45 at £89, the MT-65 at £130, the MT-70 at £175, and the CT-405 at £245. That price places it firmly in the entry-level slot: the keyboard you bought a kid, or bought yourself before deciding whether you actually wanted to learn. For context, the same pages were pushing a Yamaha DX7 at £1,169 and a Memorymoog at £1,999 — the MT-41 cost less than a decent pedal.
The MT-41 also appears in a dealer's rundown of the Casiotone family as one of the "small, portable" models, listed between the PT-20/PT-30 portables and the larger MT-45 and MT-65. That's the most reliable positioning available: a compact member of the low end of the line, sold alongside siblings rather than as a flagship. Collectors should treat any claim about its specific features with suspicion unless it comes with a photo of the actual unit's front panel — the advertising copy simply doesn't specify what the buttons did.
One caution for anyone chasing the model's history: a stray "1981" appears glued to the model name in one low-reliability aggregation page, but it reads as a scraping artifact rather than a stated release year, and it should not be repeated as fact. Likewise, the MT-40 turns up in the same source, but nothing there establishes whether the MT-41 sat above, below, or beside it. What's left is a name, a line, a type, and a price — and for a £79 keyboard from a dealer's clearance page, that may be all the legacy it ever needed.
