Simulators of the Macchina Ridotta (MR), the very first Italian computer,
designed and built at the University of Pisa from 1955 to 1958.

This package contains the MR simulators developed by HMR.

The simulator of the 1956 MR is based on Java.
The simulator of the 1957 MR is based on C++ and WxWidgets, 
this binary distribution is for Linux, tested on Ubuntu 12.04.

The MR simulators are beta releases, development is still in progress.
They work fine, however some features are not fully implemented.
For the 1957 MR lot of documentation is still missed: research is ongoing 
to understand the details needed to correctly simulate the machine.

Brief MR chronology:
- 1955 March, start of the University project
- 1956 July, first complete design of the MR
- 1957 July, MR completed and running
- 1958 March, MR user manual, MR succesfully used for computation services
- 1959 MR dismantled to reuse materials for a second computer, the CEP
- 1961 CEP completed and running, memory of the MR begin to vanish

Brief HMR chronology:
- 2006 start of the HMR project, to rediscover and rebuild the MR
- 2008 first seminar about the MR, celebrating 50 years of the MR Manual
- 2009 first simulator of the MR based on the 1956 first design
