ChanServ changed the topic of ##yamahasynths to: Channel dedicated to questions and discussion of Yamaha FM Synthesizer internals and corresponding REing. Discussion of synthesis methods similar to the Yamaha line of chips, Sound Blasters + clones, PCM chips like RF5C68, and CD theory of operation are also on-topic.

<ej5> no idea if this is even going to work. i had to make guesses since i couldn't see some traces that were underneath ICs
<cr1901_modern> I would imagine this type of board is old enough that patching even long traces would work
<cr1901_modern> I've seen this done on MFM hard drives
<cr1901_modern> (in production)
<cr1901_modern> ej5: Basically I have faith in you :D!
<ej5> we'll see how it goes. i also have to reverse engineer PAL equations based on photos of the board :P
<cr1901_modern> ewwwwww
<cr1901_modern> I could RE PAL equations when I HAVE the damn board to something
<cr1901_modern> and the PAL was purely combinational too!
<cr1901_modern> couldn't*
<ej5> it's purely combinational, but the key is that i understand 90% how the board is supposed to work
<ej5> so i can infer what the PAL is supposed to do.
<ej5> ALSO some idiot had his 2600 games stolen. wonder if they've all been dumped.
<cr1901_modern> Why is he an idiot?
<cr1901_modern> (And even if he is, he didn't deserve to have his games stolen)
<ej5> if an individual game is worth $100k and you show it off on youtube, and your address is not hard to find...
<ej5> then it really ought to be in a bank vault with proper insurance
<cr1901_modern> He still didn't deserve to have it stolen
<ej5> of course not
<cr1901_modern> Although if some good comes out of it, I hope the person who stole it dumps it
<cr1901_modern> if it isn't dumped
<ej5> i have mixed feelings about that. he ought to have dumped them all.
<ej5> if someone stole them to dump them, then wtf
<cr1901_modern> Yea I'm not doing a good job explaining my feelings.
<ej5> i don't like it when people hoard a ROM/game when there's no dump available.
<cr1901_modern> First off, yes he should've dumped his games. Otherwise ppl rightfully so can be angry w/ him for hoarding
<cr1901_modern> '>(11:08:06 PM) cr1901_modern: He still didn't deserve to have it stolen
<cr1901_modern> ^This is a visceral reaction from me
<ej5> oh i totally agree
<cr1901_modern> Like, I don't believe someone carrying $5000 on their person _deserves_ to be robbed either.
<ej5> in fact, this is another good reason to dump everything you have
<ej5> if it gets stolen, then you want to be able to have a backup
<ej5> anyway that theft makes me suspicious, apparently they only stole the safe with the games
<cr1901_modern> We lost a very valuable NES prototype, even with crowdfunding, to a hoarder in May. Chances are it will bitrot before it's dumoed
<cr1901_modern> so I'm not exactly sympathetic to hoarding lately
<ej5> well at least the community made the hoarder quite a bit poorer.
<ej5> also one has to hope that the hoarder has some sort of will, so that after they die the game will go somewhere other than a landfill
<cr1901_modern> It's effectively worthless if it bitrots
<cr1901_modern> (Idk how long that'll be, but guessing 50 years is a ballpark MTBF estimate for something that trailing-edge?)
<cr1901_modern> And we're at ~30 now?
<ej5> hard to say
<ej5> is it an EPROM?
<cr1901_modern> I believe so
<ej5> oh, that's not so good then
<ej5> what did the game sell for?
<cr1901_modern> $12,000 thereabouts? Crowdfunding raised $7000 IIRC
<cr1901_modern> it's utterly ridiculous
<ej5> that's completely batshit insane
<cr1901_modern> Retro-gaming-prices dot txt
<cr1901_modern> Tbh, on a practical level, "actually makes a meaningful difference in improving ppl's lives" practical, I shouldn't be so sad.
<cr1901_modern> But I just get really sad when I see an opportunity to preserve knowledge that is at risk to be lost, esoteric or not.
<cr1901_modern> Bad enough that modern life is a ugly set of bootstrap problems where we've forgotten where we've come from (either due to apathy or lack of bandwidth to document it all. Or fires destorying records like Herostratus did.)
<cr1901_modern> Actually, scrap that last one. Herostratus destroyed a temple, not a library. My mistake
<ej5> one good typhoon or earthquake hitting taiwan would end the world's ability to manufacture high tech devices.
<ej5> i've talked to some folks from the Long Now foundation. we've got about 30 years left.
<cr1901_modern> I think the most frustrating thing is: it's not like we don't know ahead of time what can/will go wrong in cases like this.
<cr1901_modern> I suppose that's the one "beauty" of long term problems
<cr1901_modern> Is that we tend to know the "why", and "how" they happen. But we don't actually f***ing FIX them
<ej5> fundamental human flaw: we cannot plan long term. it's not possible for us.
<cr1901_modern> Ozone layer hole seems to be the one exception
<ej5> <soapbox> people like to say that global warming is our existential threat. i say that we are our own worst enemies.
<cr1901_modern> So I'm not going to deal in absolutes here :P
<cr1901_modern> Only a sith does- *taken off the stage by a hook*
<ej5> as a species we just can't deal with very slow moving, long term threats to our survival.
<cr1901_modern> I think degrowth is possible. I think energy austerity (which I maintain is different from degrowth) will cause society to collapse b/c it will NEVER be accepted willingly.
<ej5> sure, but you're an engineer thinking about engineering solutions
<ej5> the fundamental problem is that most people think/vote moment to moment
<cr1901_modern> Ppl have this wonderful habit of not being willing to give up modern conveniences once they have experienced them for long periods of time
* cr1901_modern nods
<cr1901_modern> Tbh, Idk how many of _my_ modern conveniences I'd be willing to give up
<cr1901_modern> I would genuinely rather be dead than give up electricity
<cr1901_modern> I already know I would be unable to adapt to that
<ej5> it's a challenging problem and even if you solve it, you'd have to convince everyone else on the planet to change their behaviors for something that is ~30 years out
<cr1901_modern> An implemented solution will be ugly and done by force (take that as you will) if it's done at all
<cr1901_modern> But people prefer an order filled with injustice to a chaos trying to fix injustic
<ej5> even that is challenging. sometimes i imagine what a dictatorship by an engineer would look like. it sounds easier
<ej5> but ultimately you (as a dictator) still have to convince some people to implement your plan
<cr1901_modern> I have no public comment about that, sorry :P
<ej5> tough nut to crack. it's not impossible, but it sure seems like it is.
<cr1901_modern> Potentially unpopular opinion re: engineers in leadership roles. A public forum doesn't allow me the nuance I want :P
<cr1901_modern> I will say that it is in vogue to shit on technical expertise lacking humanities training at all costs
<cr1901_modern> Which I think is oversimplifying. E.g. Ppl at Palantir have the humanities background. They don't give a shit.
<cr1901_modern> Btw, Idk if I announced this to the room yet, but I'm prepared to know. PET/CAT scans came back; I am cancer free. I still need to finish all 8 rounds of chemo tho (currently on round 5)
<cr1901_modern> I'm prepared to tell the room*
<ej5> whoah! that's really good news!
<cr1901_modern> Indeed :D. It gave me a motivation boost for sure.
<cr1901_modern> Just need to finish a bunch of contracts and set aside a chunk of time to go back on my Yamaha and ISA bullshit
<cr1901_modern> Oh and I still can't solder till prob November :(
<ej5> aw
<cr1901_modern> ej5: Well more specifically, I don't want to risk an infection if I burn myself.
<cr1901_modern> I already had to go back to the hospital for a fever, but there was NOTHING I could do about that one. Being careful around others wouldn't have prevented it.
<cr1901_modern> (Some bacteria in my colon got in my blood. B/c body was being a f***)
<cr1901_modern> I would... like to avoid a repeat of a hospital visit due to bacteria or infection.
<andlabs> microchannel adlib?
<andlabs> alert LGR
<andlabs> he'll probably try shoving it into his giant PS/2 tower
<andlabs> =P
<ej5> more likely, he'll be oblivious of its eventual release until some rando fabs it out and slaps his own logo on it, then LGR will tip his hat to said rando.

Stilett0 is now known as Stilett0-out
<cr1901_modern> ej5: To be clear, this is the stuff I mean by degrowth: https://twitter.com/laurentbercot/status/1162846626945339393 Maintenance mode should not be a dirty phrase.
<ej5> makes sense
