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
<natarii> probably a long shot, but i figure this is a decent place to ask: anyone know if the program eprom from this has ever been dumped/made available? https://www.cryptomuseum.com/spy/owvl/32620/index.htm
<natarii> the voice roms are on that page, but there's no code in them
<cr1901_modern> Well this would be a good place to ask. But I'm afraid I don't know offhand.
<natarii> the site has a contact address which i'll probably end up emailing. no idea what will come of that

<andlabs> maybe??? I don't imagine that being the soundtrack of Muscle Bikes
<andlabs> =P
<andlabs> but yes, it is the soundtrack of motorcycles
<Lord_Nightmare> *sigh*
* Lord_Nightmare adds a chalk mark to the board
<Lord_Nightmare> https://xkcd.com/927/
<cr1901_modern> Why sigh?
<Lord_Nightmare> yet another flux imaging device
<cr1901_modern> What's the harm as long as you're not locking libraries into a contract?
<Lord_Nightmare> Foone: add it to 'the list(TM)'
<cr1901_modern> Multiple impls is good IMO
<cr1901_modern> And I certainly hope you don't sigh if/when I get _my_ device done :P
<Lord_Nightmare> nah, i'm not upset, i'm just a little jaded that there's more and more of these devices. for all i know that one is a good one
<Lord_Nightmare> I personally prefer the open source/design ones
<cr1901_modern> Well, I can't promise mine will be good, but it'll be foss
<Lord_Nightmare> if you want to talk design issues etc, chat with philpem
<Lord_Nightmare> the discferret was designed that it could also talk to MFM/RLL disks, but ran into speed issues on certain disk types
<cr1901_modern> Sure, will do. Note that discferret has much more noble goals than I do
<Lord_Nightmare> the MFMulator, which uses a beaglebone board, doesn't have those issues, i don't think?
<Lord_Nightmare> although even that may not be fast enough for RLL and similar disks
<Lord_Nightmare> and ESDI is right out
<cr1901_modern> >but ran into speed issues on certain disk types
<cr1901_modern> Well, at minimum an MFM drive spins 10 times faster than floppy
<Lord_Nightmare> ESDI is an abomination
<Lord_Nightmare> its trying to do IDE-style data streams over a two cable MFM/RLL interface
<cr1901_modern> actually not sure that matters
<Lord_Nightmare> its grotesque
<cr1901_modern> 250kbps vs 8Mbps
<Lord_Nightmare> cr1901_modern: it does, you want your signaling path clean with as little analog interference as possible
<cr1901_modern> What I was getting at is that, for a given RPM, the write clock is what matters for determining reading speed.
<cr1901_modern> if you banged out bits on a floppy interface at 3600 RPM
<Lord_Nightmare> it might not be 100% necessary if all you're doing is floppy stuff, but better to overdesign the analog signal path with a big error margin, than to underdesign it and have major issues reading
<cr1901_modern> reading at 3600 RPM would still be 250kbps
<Lord_Nightmare> also overdesigning it means component drift is less of an issue
<Lord_Nightmare> caps going out of spec etc

<Lord_Nightmare> making an ESDI device emulator using CF or SD cards would be a huge boon for people with machines which only had an ESDI interface
<Lord_Nightmare> certain lisp machines, and some other obscure stuff
<Lord_Nightmare> IDE took over hard as soon as it was available
<Lord_Nightmare> because ESDI was bullcrap
<andlabs> can we have a fully open SCSI SD card interface that has full compatibility
<andlabs> also ti seems this thing is specific to the HxD emulator?

<mrspicy002288> So do you know about the SWL01?
<mrspicy002288> I doubt the actual wave ROM is serial audio though
