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.

...why doesn't this thing play through the TV speakers wtf
<andlabs>
...wtf why is this still not producing any sound
<andlabs>
oh wait no, it's my TV being super quiet for some reason
<andlabs>
I don't get it
<andlabs>
the TV I have is super quiet with the MSX
<andlabs>
super loud with everything else
<Lord_Nightmare>
ej5 afaik the character ROM is a messy aluminum custom ibm packaged thing on one of the 5100 boards
<Lord_Nightmare>
and properly dumping it by desoldering would require schematics and stuff which we don't necessarily have
<ej5>
oh geeze
<ej5>
yeah there's not that many of these machines left operating which makes it hard to reverse engineer
<ej5>
hmm although if the video is slow enough you could run the video out + h/v sync into a Saleae and digitize it that way
* whitequark
whispers "glasgow"
<whitequark>
there's an example of capturing rgb video in realtime, with frontend softare even
<andlabs>
I'm still not fully sure what glasgow is or whether I can make direct use of it somehow
<whitequark>
andlabs: have you ever played with python code in a REPL?
<whitequark>
just plug in a few different things together and see what happens
<andlabs>
well yeah =P
<whitequark>
imagine being able to do that but with hardware
<whitequark>
that's what glasgow is for
<andlabs>
heh
<andlabs>
all right
<whitequark>
digital hardware mostly, though it's not completely restricted to that
<whitequark>
i can go from "gee i wonder if i can interface with this floppy drive i have on my desk?" to captured data in a few hours, a few days for a finished applet that can be checked in
<Lord_Nightmare>
someone had a youtube video of the 5100 running one of its self tests which prints all of the characters to the screen
<Lord_Nightmare>
and i used that to manually digitize them
<Lord_Nightmare>
which is where that fontstruct font came from
