Recently
i was trying to repair a voice module kit (possibly about 10 years old from
Völkner Elektronik, Braunschweig?) which used the YC8256M voice recorder
IC and an 41256 RAM for storage and i could not find the schematics for it.
Thanks to Hans at the fu-berlin i was able to get a copy and this voice recorder kit is here for viewing for those interested in this application.
In addition, i got some application notes for the Winbond ISD1400 Series single-chip voice record / playback devices, the Winbond ISD2560/75/90/120 single chip, multiple messages voice record / playback devices, the ChipCorder ISD1400 and the ChipCorder ISD2500.
