The
Datamath Calculator Museum DCM-50A (TMS0800) is based on the generic
DCM-50A
Platform to access all features of calculators based on Texas Instruments’
single-chip calculator circuits and covers designs based on:
| •
TMS0800 Family • TMS0830 Family • TMS0850 Family |
With many of the single-chip calculator circuits either designed for Texas Instruments' proprietary applications or developed for OEM manufacturers, available documentation of their features is rather scarce and we are committed to provide as much information as possible to the calculator enthusiasts and we document our observations and findings here.
The Technology Section of the Datamath Calculator Museum features under Calculator Chips "Datasheets" of the mentioned product families.
Characterization of Single-chip Calculator Circuits
Work-In-Process.
