From the project
TLCS-90 ROM Reader
TLCS-90 ROM Reader is custom made tool intended to read the inner ROM content that TLCS-90 series Toshiba MCUs have internally, at least for the models which support it.
Devices in the TLCS-90 family from Toshiba are MCUs with a Z80 core and a quite similar instruction set, but they have additional features than the original CPU from Zilog, such us: - Internal Counters - Wathdog - A/D converters - Serial port support - Stepping motors support - and more...
