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.

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

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?

So do you know about the SWL01?

I doubt the actual wave ROM is serial audio though
