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. Channel logs: https://freenode.irclog.whitequark.org/~h~yamahasynths
<m4t>
got the chip removed. tried chipquik + hot air from the backside, couldn't get it to budge
<m4t>
got it from the front. but man that stuff is a pain to clear from the holes
<m4t>
keeps clogging my sucker
<whitequark>
yeah

What a strange bug... literally typing anything in any GUI app caused it to stop responding, as if the keyboard driver was hung. Until I logged off...
<cr1901_modern>
I soldered for the first time since treatment began in May a few days ago (I wore a mask)... I think that's an important milestone
<cr1901_modern>
cc: ej5 ^^ Maybe soon I can build a Snark Barker lol
<ej5>
nice

place your bets...does it still work? :o
<m4t>
ugh the friggin chan3/chan4 switch just snapped off!
<m4t>
:(
* cr1901_modern
cringes
<cr1901_modern>
err winces*
<m4t>
im doin both!
<m4t>
i got sound but bad super staticky picture, i figure it is the lack of shielding
<m4t>
i guess super glue will hold it in place...but man!!!
<m4t>
i think it *was* on ch4 tho
<m4t>
heh :/
<m4t>
works fine!
<cr1901_modern>
Well if it's any consolation, I just lost hours combing through the source to a program trying to add a feature, only to find out it's actually supported and documented in the man page.
<cr1901_modern>
that was my night
<m4t>
lol ;(
<m4t>
it's not wasted if you learned more about the program
<cr1901_modern>
yes, but that was _really_ hidden
<m4t>
hmm maybe i broke it when i was moving the board around
<m4t>
leaning it on the edge...i figured it was resting on the connectors
<m4t>
think superglue would hold enough for it to be usable?
<m4t>
anyways, i dont think i broke it by leaning it. it doesnt protude further than the other connectors
<cr1901_modern>
I wouldn't know whether superglue would be okay here
<m4t>
superglue is hit or miss ime
<m4t>
normally miss
<whitequark>
i guess they never miss huh

cr1901_modern: you asked if the opcode studio 128x will work on a modern computer
<andlabs>
it probably could, but I would need a RS232 to USB converter
<andlabs>
and some drivers
<andlabs>
it is possible, because someone on youtube did show it working, but they lost the source code in a drive crash
<andlabs>
I plan on just reverse engineering the official drivers >:3
<andlabs>
and I just bought said converter cable
<andlabs>
I also just got a great deal on a steinberg USB audio interface, some recent version of cubase, and steinberg sequel 3
<andlabs>
and a mic
<andlabs>
GOING ALL DAY
<andlabs>
*GOING ALL IN
<andlabs>
[15:11:06] <+andlabs>bought two things from that the_shareware guy (synthCart 64 and recreation geoRam module)
<andlabs>
[15:11:06] <+andlabs>ebay was dumb and split them into separate packages
<andlabs>
[15:11:06] <+andlabs>the guy noticed and combined the shipping and refunded the difference
<andlabs>
[15:11:06] <+andlabs>paypal says I got a refund of £6.00
<andlabs>
[15:11:06] <+andlabs>ebay says I got a refund of £0.52
<andlabs>
[15:11:06] <+andlabs>?????
<andlabs>
[15:11:39] <+andlabs>a computer to use these with will have to wait but I might as well get them now while they're still being made
<Lord_Nightmare>
i couldn't find my usb serial adapter and didn't want to get burned with a fake/nerfed prolific or ftdi adapetr, so i ended up buying one of those ftdi-branded evaluation adapters they sell as an 'example reference part' to prospective customers
<Lord_Nightmare>
its expensive, but its pretty much 100% guaranteed to be a legit working part
<Lord_Nightmare>
whitequark: generic usb serial stuff, interfacing old things
<Lord_Nightmare>
the prolific adapter i had was not only a clone but also buggy, the auto-fifo-cts-rts stuff was broken
<Lord_Nightmare>
the ftdi adapter i had was PROBABLY legit but i can't find the damn thing after hours of searching
<cr1901_modern>
I use a keyspan adapter whose 64 bit driver is known to BSOD occassionally
<whitequark>
i'd probably just got an ftdi board from adafruit or something
<cr1901_modern>
Do they make 12-v compatible RS232 to USB adapters? Not that I have any hardware that actually requires that voltage swing
<whitequark>
oh sorry RS232
<whitequark>
nevermind then
<cr1901_modern>
Oh Idk what Lord_Nightmare has in mind; just an idle thought
<cr1901_modern>
Oh TIL it's actually up to 15V
<Lord_Nightmare>
iirc (and i may be wrong) original rs232 was +-24v?
<Lord_Nightmare>
but almost nothing supports that
<Lord_Nightmare>
+-12v is most common, or +-7v
<cr1901_modern>
If wiki is to be believed, 25v is the maximum swing the equipment must support
<cr1901_modern>
without being destroyed
<Lord_Nightmare>
so +-12.5v
<Lord_Nightmare>
i guess i was wrong, and +-15v must have been the original spec which was later amended, but i still am not sure, i don't have the spec in front of me nor wikipedia
<andlabs>
so is my pruchase one to regret
<whitequark>
i think the dangers of counterfeit FTDIs are overblown
<cr1901_modern>
Probably not unless you have one of those old acoustic coupling modems
<whitequark>
the actual silicon works better than FTDIs anyway
<whitequark>
if you're stuck using them in windows i guess that's a downside
<andlabs>
I'm using this for an Opcode System 128X
<andlabs>
which is a 1U rack mount MIDI interface
<m4t>
this ym2612 i bought a few yrs ago works :-)
<m4t>
a few weeks ago i replaced the counterfeit ft232rl chips on these adapters i bought several yrs ago
<m4t>
the fakes have issues w/bit bang
<whitequark>
dont the real ones also have issues with bitbang
<whitequark>
marcan has shown that fakes work better
