NBD is fairly simple. I wrote a minimal server in Python[0]. It is just a few lines. 0. https://github.com/rvalles/pyamigadebug/blob/master/NBDServe...

I have used DAA recently, in my "load option ROM in RAM floppy tool"[0]. Specifically, I use it for printing numbers as hexadecimal[1], as unfortunately the ASCII standard is not arranged in a way as to facilitate this. 0. https:

I have played with HAM conversion myself[0], but my approach has been to deliberately avoid brute-force. That's not just because it'd be less fun, but also as I'd like to get these algorithms working on the Amiga itself at so

I learned the FPGA ropes by making (from scratch, reinventing many wheels) a fast interface between dbus (TI calculator link port) and a standard serial port in Verilog. It is dramatically faster than every other "link cable" avai

Author here. Optromloader made front page somehow. I will read your comments, and try to answer questions if any.

Did re-read your comment, and thought I'd point you to some code so you can quickly see how it works. Regarding trackdisk.device, you might want to take a look at: https://github.com/rvalles/pyamigadebug/blob&

While fast, PiStorm is still similar to a 030, and not anywhere near fast enough for 060 demoscene. Workbench is what it is.

I had never heard about this one. Neat. re: Amiga, it is sad that, with 256KB of ROM, they couldn't fit a key combination to call exec's Debug() in the strap module. I understand that, somehow, nobody thought about it.

Me neither, until relatively recently I found documentation for romwack. It lives in the "Amiga ROM Kernel Reference Manual: Exec"[0] book. My pyamigadebug[1] is backed by this debugger and the newer SAD that replaces it in AmigaO

Least Significant Bit, there. Tiny question, tiniest bit answer :-D To add some context, these RomTag structures reside in ROM, so they can't be edited. The table of residents is, however, in RAM. It should be possible to add RomTags t

Hey, you're not doing so bad yourself with your Amiga OSHW either! There's much work to be done with the Amiga in the OSHW front, thus this is very welcome. I intend to read your mem68k-like board's Verilog at some point in t

I can confirm something's wrong by using an incognito windows. It might have something to do with my user being new. Who knows what secret rules are in place for that. I'm hopeful this will change soon, but who knows.

Author here. I am amazed it made frontpage. openbsd's httpd seems to be handling the load well. I will read your comments if any :)
