Best practices for direct hardware programming ?

[Quranei]

Hi,

when I programmed the Amiga the first time around, I always had been using it with the operating system turned on. I was now interested into poking into the hardware registers directly. Since I often read about that you have to deactivate the operating system, I was wondering what would be the best approach to do that so I can still do something like starting the program from DOS, work directly on the hardware and after exiting, I can continue using the system again. Do I really have to deactivate everything (e.g. Exec and DOS) or only parts ?

And I'm looking for a monitor stand can support a 34" curved monitor at the bottom and have a second 24" at the top, over it. If it has a discrete base or a desk clamp, doesn't really matter. But base is preferable. A base in the lines of Ergotech WSGF Edition Monitor Stand.

Thanks

I am not exactly sure what you mean, but hope this helps:

- I think, in DOS you had some access to some registers ... at least I remember accessing registers when using for example serial port. But it was long time ago.

- In higher operating systems (e.g. Windows, Linux) you can not access hardware directly, however you have some access through drivers (if you know how to write drivers).

- If you would like to play with registers directly, I would recommend a microcontroller e.g. Arduino

- or have a look at FPGA stuff - there you can play with even lower levels (you can create registers)
