This does not look like much, but my operating system is now able to do console I/O via a character device:

  • A device manager registers available devices
  • stdio init calls open on the console device, which allocates a file structure and returns a file descriptor,
  • then console_puts calls write() on the returned file descriptor to emit the string.

The calling convention makes maximum use of registers and is not that bad.

All of this was written in hc11 .

@Wintermute_BBS thanks :)

@Wintermute_BBS like this? I will use the hc11 system to test more peripheral boards, because the bootstram rom and integrated peripherals are very easy to use.
I really need more uarts and compactflash.

First of all I need a readline() and shell, and a few api tweaks.

@gilesgoat @Wintermute_BBS i note that, thanks :)

@Wintermute_BBS it seems to be broken on the real hardware :|

@Wintermute_BBS no idea, I just dont get any serial display. Will investigate this evening. The bootstrap loader is ok and the previous monitor I wrote is also ok. So it's specific to this new code.

@f4grx@chaos.social avatar

@Wintermute_BBS could have been, since it's running at 16mhz, not the usual 8. Old monitor runs as expected.

@gilesgoat @AMS @Wintermute_BBS yep 128 bytes buffers is perfect, I have a total memory of 56k, so 1k buffers are overkill. I will hopefully have a filesystem! Homegrown to keep the memory requirements low, but extensible!

    The .zip TLD sucks, and it needs to be immediately revoked. My take: it doesn't matter these days despite having a valid concern.

    @nixCraft We can still build link honeypots with kilobytes of random words and hyperlinks.

    I just got access to Google’s new MusicLM and…

    Wow.

    No exaggeration when I say this will change the music industry. Thanks https://twitter.com/zackhargett/status/1656812761324875776 for the HT.

    @jskists @Wintermute_BBS ask them to lay a toslink cable in the bundle, we could multiplex several 9600bps links on just one.

    Imagine calling external /bin/ls just to check the file listing on your Linux, macOS, FreeBSD or Unix-like systems. Just use printf https://bash.cyberciti.biz/guide/Printf_command or echo https://bash.cyberciti.biz/guide/Echo_Command :P Avoid bloat.

    Despite hating having to type on glass, why isn't there at least one telnet terminal app for that does ANSI just like or do? And why do the few apps that support ANSI suck so fucking epically at displaying it properly?

    I just scored an apparently-working Z80 CP/M system (Xerox 820) at an estate sale. The computer lives inside the monitor, plus there's a keyboard & HUGE two 8" disk drives. One of the floppies will boot it to an "A>" CP/M command prompt. What in the world will I do with it?

    Day 108 of - Couldn't post this last night, but Mastodon is working again, so here goes.

    This is a front panel for a four-channel level meter, with two control buttons per channel. This connects into a larger system that I'm building.

    @ve7fim Thats very pretty!
