Casio MT-100
A small Casio that dealers kept listing in the same breath as the CZ synths — 768 variable accompaniments and a price tag that stayed "P.O.A."
Overview
The MT-100 is one of those Casios that survives mostly in the fine print of dealer ads rather than in glossy spec sheets. What the period trade listings do preserve is a single, oddly specific selling point: 768 variable accompaniments. That number turns up again and again across the Electronics & Music Maker dealer pages of the mid-1980s, always attached to the MT-100 and almost always listed at "P.O.A." — price on application — which tells you something about how these home keyboards were sold. They weren't racked with a fixed ticket; they moved through main-dealer channels where the shop set the number.
The MT-100 sat in the same dealer columns as Casio's CZ101 and CZ1000, the CT-series home keyboards, and the CK cassette-deck models. Collectors reading those old pages today will recognize the pattern: a Casio main dealer would run the whole family in one block, from the budget MT models up through the CZ synths, and the MT-100 appears consistently in that roster — "CASIO MT-100, 768 Variable Acc/ments," as one listing put it, wedged between the KX-101 and the MT-800. It was a catalog fixture, not a headline item.
That's the honest picture. The MT-100 was a consumer-tier accompaniment keyboard sold alongside Casio's more famous budget instruments, and the documentary record is thin on the things enthusiasts actually want to know — key count, voice architecture, whether the "768 variable accompaniments" refers to rhythm patterns, chord variations, or some combination. The dealer copy doesn't say, and no period review in the available material takes the MT-100 apart. What can be said with confidence is narrower: it existed, it was distributed through Casio's UK main-dealer network in the mid-1980s, and its most-advertised feature was a large accompaniment count that the shops clearly considered the thing worth printing.
Owners chasing one today should treat the dealer listings as the primary source and expect the usual gaps. The "768 variable accompaniments" figure is the only specification the period advertising reliably repeats, and even that is quoted from shop copy rather than a manufacturer spec sheet — so it's best read as a marketing claim, not a measured one. Everything else about the instrument's voicing, its keyboard, and its physical build is undocumented in the material at hand. That's not a knock on the keyboard; it's just the state of the record for a mass-market home instrument that nobody thought to review.
