Release id #152591 : SD2IEC Kernal 1.0

(Moving the discussion of wedge to a forum post)

If feasible, it would be nice to get the Big Three DOS wedge commands:

@ (command channel)
/ (load ,8)
% (load ,8,1)

The browser is a nice option, but the direct route is handy as well if both can be supported.

Thanks a lot, CRT! The address to patch for the start device number of the browser is $f422 (or byte $1422 in the .rom file). I actually expect this to stay the same no matter what I change in the kernal.

Let's see how much is left when the monitor is in, maybe the auto-run can be added (might be smaller than the wedge or function keys).

Comment on sd2iec-devices blocking the tape port; yes, this is probably the case with most external SD2IECs, but a lot of people are also installing these inside the machine, and then all the ports are free.

I think DOS Wedge is a good idea despite the file browser. You can make use of the command channel for other things apart from browsing the directories / disk images, too.

Although, if you need the command channel shortcuts only occasionally for, let's say, configuring the sd2iec for example, you can always use the software DOS Wedge that came with 1541 demo disk.

Great idea with this KERNAL, though I haven't tried it yet :)

Using the command channel to set up a swap list (@XS) is pretty important and a fairly frequent task. (Or does the browser support the XS function?)

Oh, I have never used that (always use autoswap.lst). Hm, I am nearly finished with the monitor and like a quite a bit. Only 41 bytes left now, let's see what can fit into that... :/. A tiny tiny wedge with @ command channel support might be feasible.

Some update: I meanwhile decided against the memory monitor, as this is probably rarely useful and could be loaded from a file for the few occasions where it is needed.

Instead I was able to include a wedge, for now including

@ for printing the error channel
@[command] for sending commands to the drive
@#[num] for selecting the device number

I will try to include selecting swap lists in the browser, too.

Adding load&run is also on my list: do you think this could simply replace the "load ,8" in the browser? Or does anyone feel the need to load programs ,8 and not execute them right away?

Can be optional, like on Action Replays:
F1-load & run
F2-load

At the moment, you can press Return in the browser to load,8,1 or Shift-Return to do load,8. Adding a third option would require a new key unfortunately...

Guess WITHIN browser everything's fine, my wish for F-Keys referred to mere KERNAL outside browser

CRT had the request for the auto-run from the browser, and it seems like a nice idea to me. I just added it and it even did not cost a single byte (I still had the load/run string in which proved to be useful now, unbelievable how wasteful I was with memory :-)).

BTW: I did remove the possibility to use the wedge commands in Basic programs and saved some bytes by doing so. It seems utterly wrong to me to rely on a modified kernal or a loaded wedge in a Basic program.

Function keys and .lst file support are next on the list.

The classic convention for load-and-run is ^ (up-arrow). Is that too costly in terms of bytespace so you can leave / as a standard ,8 load?
