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.

<Lord_Nightmare> ej5: the kensington smart mouse has a motorola microcontroller in it
<Lord_Nightmare> i'm 95% sure it is an MC68HC05C9A
<ej5> neat!
<Lord_Nightmare> try dumping it in a bpmicro programmer as an MC68HC705C9A and it should dump
<Lord_Nightmare> Mc68HC05C8 and C9 series parts were very popular in the late 80s/early-mid 90s
<Lord_Nightmare> they were the cmos evolution of the old NMOS MC6805Px series
<Lord_Nightmare> SC417834P is just a motorola custom part label
<Lord_Nightmare> inside i'm guessing is a plain old MC68HC05 series part
<Lord_Nightmare> compare the pinout and where the crystal and power pins are vs the mc68hc05c9 datasheet
<Lord_Nightmare> is the 8 pin din connector meant to connect to the serial port of a mac?

<Foone> I seem to remember that some of those have a generic connector because they can take two cables, one that goes to a mac and one that goes to a PC
<Foone> presumably one cable or the other shorts two pins out and tells the microcontroller to switch protocols
<Sarayan> thermal sensor to detect the shorting?
<Foone> I hope not!
<Sarayan> Relevant: https://xkcd.com/1172/
<Foone> someone quoted that at me yesterday because I was talking about wanting a heated keyboard
<Sarayan> (hopefully, *not* a projet)
<Sarayan> Ah yeah, saw that
<Sarayan> incidentally, the cat is against the laptop hot air output, and does not seem to be melted more than usual
<Foone> I would hope your cat wouldn't melt
<Foone> that would be way too hot
<Sarayan> Well, she's rather in blob mode when she's sleeping against, or worse on, me, so the default melting level is high already
<Foone> good point. cats are usually a liquid
<Sarayan> indeed
<sorear> probably the temperature affects the viscosity
<Sarayan> nah, they're always both clingy and slippery at the same time
<sorear> ~viscoelasticity~
<andlabs> https://en.wikipedia.org/wiki/Professional_Graphics_Controller "Clones: - Matrox PG-640, PG-1280 and QG-640 (for the DEC MicroVAX)[2]" hmmm
<andlabs> [10:18:00] <Foone>I would hope your cat wouldn't melt
<balrog> Sarayan: cats hate Apple M1 computers :p
<Sarayan> balrog: Not enough heat?
<andlabs> oh balrog I'm still curious what items your father wants to give away
<balrog> andlabs: I don't have a comprehensive list yet
<balrog> Sarayan: correct :p
<andlabs> ok
<balrog> andlabs: if you or others are interested, I'll try to dig up a list
<balrog> I thought I had a partial one
<andlabs> sure
<andlabs> mostly out of curiosity at the moment though
<cr1901_modern> I am very sorry your acct got locked for "fuckign stupid shit" Foone

<Sarayan> Hey cr, did you trace the lfo of the 2151 or you never reached that?
<cr1901_modern> Never reached it: nukeykt did it afaik and shared his notes w/ jotego
<cr1901_modern> Maybe I'll get to it at some point.
<Sarayan> Aaron is not really convinced of his implementation
<cr1901_modern> Aaron?
<balrog> Aaron Giles just rewrote the FM emulation in MAME
<cr1901_modern> Ooooh right
<cr1901_modern> Any chance he could idle in here? (I think I asked this before)
<cr1901_modern> Also semi-related, I've been _considering_ making a discord bridge, since lots of MAME ppl are on discord rather than IRC (and I've no plans to retire the channel)
<Sarayan> I've never seen him on irc
<balrog> which discord would you bridge to?
<balrog> 1bitsquared?

<cr1901_modern> balrog: I don't know. Prob not on topic for 1bitsquared
<andlabs> I can never remember if aaron giles is supposed to be a good person or not
<cr1901_modern> There is already a discord dedicated to composing w/ yamaha chips. The main reason I don't want to bridge to that (beyond the fact that I don't even know if they're intereted) >>
<cr1901_modern> is that there is not much overlap in communities and I want to be able to filter ppl who would cause trouble (read between the lines here)
