Music Chime Information Database

Overview

Documenting dedicated chime devices, primarily of Japanese manufacture.

Scope

Electronic only, no electromechanical. Currently limiting this to the sort of devices that are intended for permanent installation in a rack or similar. Not documenting things like door chimes at this time.

Sound Sources

Manufacturer Model No. Chime Types Synthesis Method Production Start Production End Audio Samples Notes
National/Panasonic WZ-245 Westminster Digital control of analog tone generation 1980s 2005/03/01 Reduced version of WZ-250. A few parts not populated, otherwise identical. Manual
National/Panasonic WZ-248 Westminster (2 variants), Memories, ding-dong (repeated 3x) PCM 1990s? 2006 CPU-less. Uses companded PCM. Manual

TOA EC-012 4-note
TOA KT-140 / KT-011 / KT-011N Westminster Digital control of analog tone generation Late 1970s Sequenced by discrete logic. Production order is 140 → 011 → 011N src. KT-011N spec sheet. KT-140 spec sheet. KT-140 manual. KT-011 spec sheet.
TOA ML-102 2x Customer option Unknown 1ch?
TOA ML-202 / ML-202N 2x Customer option Unknown 2ch? MN6221 series melody IC, according to [src]. Although [src] claims different than early TT-021B models which are confirmed MN6221TA? Two UV EPROMs inside [src], why? Sometimes referred to as the Hasuda system - 蓮田系
TOA ML-301 / ML-301B Westminster, 4-note FM (YM2203) in early units, PCM in later units Reduced version of ML-304. Program shared with ML-304 MCU, selected by hardware. Newer production units use sampled audio (OKI MSM9810) and different CPU [src]
TOA ML-304 / ML-304B / ML-304BLK Determined by MELODIX CARD FM (YM2203) 1987 [src]
TOA ML-1000 Determined by MC CARD PCM via DSP
TOA TT-021/TT-021N Westminster Program timer with integrated sound source. sample
TOA TT-021B (early model) Westminster Melody IC (MN6221TA) sample. Z84C000 CPU. 256 kbit ROM, seems huge for a timer? Is this actually 021B and not 021/021N?
TOA TT-021B (later model) Westminster FM (YM2203) Program timer with integrated sound source (same sound as ML-30x series). sample
Toshiba ACH-100WA Westminster [src] Half-rack. Hardware probably same as ACH-101?
Toshiba ACH-101 Westminster, 4-note FM (YM3812) [src]
Toshiba ACH-400WA Half-rack. TMS3615 octave synth. CPU-less, sequence data on UV EPROM?
Toshiba ACH-401 2006 [src] FM, according to [src]. Board has large 0.7“ and 0.3” DIPs with stickers, large QFP, also what might be YMF262+YAC512 pair???

  • Archive all links
  • The dates on the Panasonic stuff are sus. For example, production start in 2001 for WZ-255, but 98.02 on footer of manual PDF?
    • My WZ-248 has early 90s date codes
  • Figure out 202 situation. Some comments say it is MN6221 series, but this contradicts hoi9007's 202N PCB shots: https://twitter.com/hoi9007/status/1223509959977000960. Possibly melody IC on 202, and CPU based on 202N? No RAM!!!
  • Panasonic TD and TA series program timer / bell timer
