Are there any #MC68000 #mc68k gurus in the audience?
If a program running in usermode accesses the vectors via a data access instruction - what does the 68010 indicate on the function code pins?
Are vector reads escalated to being supervisor code/data reads, even though the code which triggered them is user-mode?

I'm trying to figure out why dereferencing a null pointer is 'fine' on a real #UnixPC but causes problems with the FreeBee emulator (if I disable vector access promotion).

I cannot explain how much euphoria this is giving me. I've just had a happy cry!!!

I love and want to be The Dark Knight more than anything <3333

Baby boy.

The euphoria I get thinking about being The Dark Knight is so good and makes me smile every day. I feel amazing, wonderful, incredible, it gives me so much joy! <3

This is the thing I am most passionate about! <3

Sneak peeks! I might reopen a few slots here pretty soon :3 either on the 7th or 8th

(If you don't know this is my alt art style, it's bolder and even more vibrant than the regular one)

Prices! If you have forgotten (shaded only)

Headshot : $10
Halfbody : $25
Fullbody : $40

I might not be reopening comms in this style again for some time, unless a lot of people show interest, that is. I'll be tagging those who asked to be tagged when the time comes ^^

Condolences.

Mike Karels of Berkeley Unix/BSDi died of a heart attack on his way home from BSDCon.

Karels was responsible for implementing TCP/IP on BSD, which was later ported to Linux. Since you're reading this, you are benefitting directly from his work.

RIP, Mike. We won't forget you.

okay so this is badass

one of my most cherished and irreplaceable retrocomputing devices is my peerless Roland SC-55.

while the MT-32 has been emulated quite well, the SC-55 always lagged behind in emulation - most attempts at it sounded pretty terrible, even using good soundfonts.

(and hauling around my SC-55 + midi & 3.5mm & usb cables just to play games in dosbox was painful)

in comes Nuked-SC55: it is a chip-level emulation project that just *nails* it.

it took about 30 seconds to build with cmake. i'm now going to try integrating it with dosbox, so i can finally play 90s DOS general midi games! (ultima viii pagan, here i come)

demo songs with the LCD screen (which is also accurately emulated!)

nuked-sc55 source:

fwiw to compile (requires cmake):
mkdir build
cd build
cmake ..
make
