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. |

reasonably quick fast loader plus easy to handle file browser. quite nice to have!
of course, my old combo "5" (JiffyDos KERNAL on my EF3) "↑FB*" (File Browser) + Return somehow is fixed in my brain (and not much harder than "6" (your KERNAL) "Shift+Run/Stop") but with this new solution it ain't a problem anymore to launch file browser without resetting SD2IEC - no matter whether FB is on currently mounted image or not.
Suggestion: Implement F-Keys for stuff like LOAD, DIR, LIST, RUN |

Just for completeness: Enthusi (obviously :-)) suggested to squeeze TurboTape in (which looks feasible). Is there anyone else who thinks that is a good idea? I am a bit in doubt, as an SD2IEC typically blocks the tape port, but it might make sense if people want to use one or the other without changing the kernal. Opinions? |

Blocking the cassport for a device to transfer data through the IEC port is a bad idea anyway :-) |

It's your project, but my feeling is if the premise is to be "a very useful kernel specifically for SD2IEC users", the fact that the vast majority of SD2IEC users have the tape port blocked means that any leftover space would be better used on optimizing outcomes for SD2IEC-specific use, and/or very general-purpose stuff like F-keys, rather than accounting for the narrower audience of people using external SD2IEC power, or using SD2IEC under emulation. |

I originally wrote this kernal to make my life easier when creating/testing cartridges (where you need mass storage, but do not have the module slot free). I meanwhile feel the need for a memory monitor in these cases, so I will investigate if I can fit a simple one in. Holding Run/Stop while resetting would then skip module start and directly enter the monitor. |

"fit a simple one in"
And a fast-loader and a file-browser.
Where did you find all that free space?
I made a Kernal once and without serial comm and tape functionality I only managed to squeeze SJ-load for the SD2IEC (no drive-code) and a few F-key commands in.
(anyway you'd publish the source, maybe? ;) ) |

:-) I decided on eload, because it is a pretty compact fastloader. The browser is the largest part with roughly 1.5 kb. Overall I was able to find 2565 bytes and I really used every available tiny segment (some are only 4 bytes) without wasting a single byte. When it is all done I am happy to share the source, although it is obviously a tad convoluted... |

I dont recall this but I posted the rs232 areas I used back then:

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. |
