Arduino MEGA 2560 ISA Slot Shield > under development <

There is considerable interest in retro computing including the early Industry Standard Architecture cards.

This shield implements an ISA slot with the following features:

I/O ports are memory mapped into the Arduino MEGA address space.
On card memory is mapped into a window in Arduino MEGA address space.
Interrupts are mapped to Arduino MEGA input pins to generate real hardware interrupts.
The ISA DMA engine and refresh controller are emulated.

The success critera for this project include correct operation of the AdLib, SoundBlaster, Gravis UltraSound, and CGA/EGA/VGA cards.
