DUAL(ID:4664/dua002)

autocoder with emulated floating point 

alternate simple view
Country: United States
Designed 1953
Genus: Low-level Autocoders
Sammet category: Numerical Scientific

for Dual coding ability

Schlesinger UC Los Alamos Scientific Lab 1953

Dual coding system - interpreted autocoder with emulated floating point system that also had machine language components. Based on 607 system subset that was compatible with IBM SO2, to ensure portability and security.

One of languages describe by Backus 1979 as creating a "synthetic computer"
