French CII's Mitra-15 in SIMH. Work in Progress
A developer is building a simulator for the Mitra-15, a 1970s French minicomputer, using the SIMH framework. The project aims to preserve computing history by documenting and emulating hardware that lacks surviving technical resources.
Why it matters
Digital preservation of obsolete hardware is critical for maintaining the history of industrial and scientific computing.
https://ajovomultja.hu/mitra-15 A Mitra-15 Simulator for SIMH This is a preliminary version. For now, my code compiles, but it is still not a true Mitra-15 simulator; rather, it is a tentative effort. Many thanks to Pascal Chour for the very useful documentation available on his website: https://www.pascalchour.fr/ressources/cii/mitra15.htm
As my C is rusty (pun is intended) I started with an existing SDS 940 simulator for SIMH and slowly modified it towards Mitra-15's characteristics.
The Mitra-15 is a microcomputer that features interesting concepts, such as the ability to program input/output peripherals using microcode, instead of using an external mechanism such as DMA. https://en.wikipedia.org/wiki/Mitra_15
