Thomas CherryhomesNot only has the Frob #Atari2600 #Gamedev System for #Apple2 been #reveng, Golden Child from #MAMEDEV has emulated it in MAME!

#Apple2 #Atari2600 Frob #RevEng status: mostly done. a few nets not 100% certain, so i'm pinging them out on my actual board using a multimeter in continuity mode. Thanks to Bradley Bell and Curt Sampson.
stateful beingalright i just did a badass darkwavey jungle loop on the thing and it crashed and rebooted :(
the other funny thing about the #mc303 is that the #datasheet for its #cpu (#motorola iirc?) is nowhere to be found
but the datasheet for sibling models are available. one of the things i'd like to do one day is piece together that datasheet and instruction set and #reveng the mc303...
Code of Amor 💘Reverse engineering designs from crappy pictures and experience... I was curious as to how this PWM fan for Pi worked and whether it would use a similar approach that I would have done. The answer: yep, pretty much. I might make it a bit more energy efficient by using a tiny mosfet instead, though. Maybe.

scySooo … I ditched the logic analyzer and pulled out my scope and … I'm afraid I have to peel off that label again.
Because I don't know if that looks like #WS2812 to you, but it sure doesn't to me. Apparently there's a short pulse, followed by a another pulse that's either short or long. I guess that's the binary encoding.
I'm open to suggestions which #LED protocol that is.
Alt text has some more details and timings.

Strange electronic devices that you have partially reverse engineered should have a label explaining why they are strange electronic devices and what you have reverse engineered.

One idea to explore further from today's Sustain Together meeting:
A legal defense fund and team to fight against take-downs of legal reverse engineering discoveries.

It is *always* worth searching around to see if someone, somewhere has already done just what you describe - especially after a device goes EOL.
I think we're going to see a lot more citizen-level reverse engineering projects bare fruit, as the #enshittification epidemic spreads like #covid.
We're fed up, and those of us who have the skills and time to do these kinds of projects, *are*.
I know I am.
I just saw a guy #reveng his Phillips electric toothbrush. Another replaced the controller board of an otherwise unusable video router with his own microcontroller and code. Tip of the iceberg.
#ColecoAdam A few weeks ago, I posted how to use #MAME's castool utility to generate a .WAV file containing the formatting tracks for a center directory DDP.
When recorded to an actual data pack, e.g. in an audio tape deck, this can rejuvinate a degraded tape (it will however delete any existing data) WITHOUT THE NEED FOR A DONOR TAPE.
I will be recording a video shortly showing the entire process of constructing the blank DDP image, the WAV file, and recording the WAV file using a USB enabled audio cassette player.
Hopefully this will be a great preservation boost for data packs, both factory and third-party alike.
I feel horrible even attempting to pull every string I may or may not have, but...
I have a #GRiDCASE 1537 that was govt surplus. It malfunctioned, and Curt Vendel offered to fix it. After almost 5 years, I got it back, but it's in pieces, and am looking for some1 to fix it.
This is a tall order, because the schematics for this thing are classified, and will require someone versed in hardware #reveng to do it.
