The Sinclair QL Forum

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 not the
point of the exercise, its the fact that you can run QDOS 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.

Great experiment.

I've run a Jupiter Ace emulator for SAM Coupé, running as the SIMCoupe emulator...!

There's also a VIC-20 emulator for ZX Spectrum that can run on an emulated ZX Spectrum, e.g. with Spectator on QDOS on Q-emuLator on Wine on Debian...!

Emulation is fascinating, and recursive emulation is almost philosophical

This is awesome!
Shame iDOS was pulled by Apple

Looks like iDOS is coming back! http://www.appscout.com/2011/01/idos_do ... s_to_t.php

Yep, if and when it does appear, you have to be quick
