XORTRAN: A FORTRAN IV Neural Network for IBM 1130 and PDP-11 Computers

Summary

XORTRAN is a multilayer perceptron neural network written in FORTRAN IV that runs on vintage IBM 1130 (1965) and PDP-11 (1970-1980) computers. The project implements the classic XOR problem on historical hardware, with the IBM 1130 version expected to take around 30 minutes to train on actual hardware, though this couldn't be measured due to the available IBM 1130 not being fully operational. The project is hosted on GitHub as an open-source implementation of neural networks on retro computing platforms.

XORTRAN is a multilayer perceptron (MLP) neural network written in FORTRAN IV, compiled and executed for both the IBM 1130 (1965) and the PDP-11 (1970~1980).
For the IBM 1130, the code is written in IBM 1130 FORTRAN language from 1965, the manual for which can be consulted online.
Training the network on the real hardware is expected to take probably around 30 minutes, however, this couldn't be measured, as the only IBM 1130 available to me is not fully operational.
