Por supuesto el resultado es lentísimo, como el autor comenta en su mensaje:
The iPad with the iDOS app incorporating the DOS BOX emulation (now
removed by Apple) running in DOS a program called QLAY which itself
emulates the operating system QDOS
You will see from the video that QDOS runs really slow, however that is the
point of the exercise, its the fact that is does run on a modern day piece
of kit (iPad).
The whole thing was filmed in stages using the iPhone and edited together
using the iMovie app before uploading to YouTube.
Because of the various emulations going on the whole boot up sequence
takes over 10 minutes so this has been edited down for aesthetic purposes.
Esto me recuerda el emulador de Jupiter Ace para SAM Coupé y el emulador de VIC-20 para ZX Spectrum... Sistemas que a su vez que podrían ejecutarse con emuladores sobre otros emuladores...
