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.

Ah, thank you! It seems I was a bit more aggressive in kicking out RS-232 related stuff.

One thing I kept intact that if you try to access device# 1 or 2 you get an "device not present" error message.
Perhaps I lost a lot there.

Flashed it to my EF3 as a kernal and it will be my prime choice for most SD2IEC operations from now on. It's a great kernal!

Humble requests: I would like an auto run feature from the browser so I don't have to type RUN. A simple wedge would not be wrong either. Also, an auto-detect of active device or even just a tool generate a kernal starting with your device number.. I know.. probably just one byte to change (I'm lazy). Or just give me the address and I will make the tool (I'm not that lazy after all). @%@#%.. I can hack it!

Awesome kernal!

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

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...
