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.

Foone: gives a whole new meaning to 'eurorack'

cr1901_modern: Erm ... sounds like somehow timing went wrong.

<ValleyBell>
I actually have no idea how this can happen.
<ValleyBell>
Sonic 3's speed shoe mode only allows for 200% speed, but I think this is more.
<ValleyBell>
It sounds more like it somehow ended up with an endless loop in the VBlank interrupt handler.
<ValleyBell>
The S3 proto driver was a bit buggy, but that was mostly related to the PSG glitching when any of the FM SFX ended.
<ValleyBell>
(due to incorrect/missing bank switch code)
<ValleyBell>
andlabs: Heh - you know what? This case is exactly where my current PC hardware resides in, except in black and not transparent at one side.
<ValleyBell>
Yes, I have 2017's mainboard + CPU + graphics card in an early 2000s case.
<cr1901_modern>
ValleyBell: Thanks for the feedback, and also why the early 00s case? Where are the front USB ports :P?
<cr1901_modern>
andlabs: Yea, I'm not sure what to think about that bright green case lol

cr1901_modern: I just reused a case that my father had. I also like how it's being pretty tall, thus allowing for lots of stuff to be packed inside.
<ValleyBell>
The front USB ports are below the floppy drive slots.
<cr1901_modern>
ahhh
<ValleyBell>
It's the small solid looking rectangle in the image.
<ValleyBell>
It's a lid you can open.
<ValleyBell>
(I don't have the lid anymore, but I don't need it anway.)
<cr1901_modern>
I don't have the space, so my next computer is likely to be a mini itx or something small that still has more compute power than my current laptop (which is showing its age). I need something fast for compiling, not for games
<cr1901_modern>
(oh and more RAM)
<ValleyBell>
The case originally had a floopy drive with a pretty strong spring and it was really funny how the disks get "spit" out upon pressing the eject button.
<ValleyBell>
It's too bad that modern motherboards don't have floppy connectors anymore
<cr1901_modern>
Foone made a 3d printed rig to catch floppies which get spit out
<ValleyBell>
lol
<cr1901_modern>
convert the floppy signals to USB :P. There's a USB storage class for 3.5in floppies.
<ValleyBell>
I actually tried one of those floppy -> USB adapters
<ValleyBell>
but it worked terribly.
<andlabs>
just get a FD-55PUB
<andlabs>
either an official TEAC one or one of the rebadged ones
<andlabs>
I have an IBM branded one
<cr1901_modern>
that part number returns nothing for me
<andlabs>
then you can use ufiformat on linux to format 720k DSDD and 720k, 1.2M, and 1.44M DSHD disks
<ValleyBell>
yeah, I can't seem to find anything related with that number either
<ValleyBell>
The slot of the former floopy drive is not occupied by a multi-card-reader thing that also has some additional USB ports.
<andlabs>
oh
<andlabs>
FD-05PUB
<cr1901_modern>
Ahhh I thought ValleyBell wanted one in the form factor that fits in a machine :P
<cr1901_modern>
Since a number of USB cards have at least one internal port you can connect stuff to
<ValleyBell>
Yeah, the initial plan was to just keep the original floppy drive reuseable.
<andlabs>
oh
<andlabs>
well in that case IDK
<ValleyBell>
I have an old Pentium II PC with 3.5 and 5.25 inch floppy drives.
<andlabs>
there is that one hting specifically for 5.25" disks
<ValleyBell>
so if I ever need to read/write floppies, I can use that one
<cr1901_modern>
The floppy part of the mass storage class has no provisions for 5.25" disks. Not sure if this affects a 5.25" floppy showing up as a small USB stick tho.
<Foone>
yeah. in theory you could make a generic mass storage device that's a 5.25" floppy (or a 3.5" floppy for that matter), but all USB floppy drives (except for maybe one) use the floppy-subclass which explicitly only supports 720k, 1.44mb, and 1.2mb 3.5"
<Foone>
the main difference between floppy-subclass and generic mass-storage is that you can format a floppy-subclass drive
<Foone>
so if you did a generic mass storage version you'd need special handling (and therefore special drivers) to do formatting
<whitequark>
couldn't you format an UMS drive too? i'm sure there's SCSI commands floppies support
<whitequark>
like, SCSI floppies
<Foone>
so... scsi formatting is weird.
<whitequark>
ok nevermind
<Foone>
it has formatting commands but a lot of times OSes only support the high level one, and if you want to use the low level ones you're supposed to use the SCSI BIOS
<whitequark>
um
<whitequark>
wait, what
<Foone>
when you boot a system with a SCSI card in it you'll often get a "press ctrl+a to enter SCSI BIOS" prompt, and it usually just gives you some settings, some diagnostics, and a low level formatting option
<Foone>
and because of that the SCSI drivers don't support it? at least on windows and out of box on linux.
<Foone>
on linux you can install sg_utils and send a manual low-level-format command, I think
