Manuel mentioned yesterday that it's not possible to hook up a cd-writer to an MSX.
Is there ever made an atempt to code cd writer software?

the CDRW as minimun writes a 4x....

that iirc is 1200KB/s.... and you needs to give that speed without any slowdown.... it is impossible in a msx . Include if you has all pre-loaded in RAM you needs a looooooot of RAM that isn't .....

offcourse you can try to find and OLD, very OLD CDRW drive that still works!... good luck!

I think moving all your MSX thingies on a big CF to PC, or via a network (think Obsonet) and then burn @ 48x on PC is faster anyway

But it wouldn't be more FUN!

NO, if you want to have fun... and want to try that yourself! waits for MNBIOS... then makes a driver egg... MNBIOs will saveyou a lot of redundant work.

and it is not FUNNY to programming a driver..... overall a CDR driver..... it is the more booooring thing that you can do!

What about sending sound analogically to an external device able to digitise it and burn a CD on the fly? Sounds a bit freak, I know

Why not just hook up a CD write with Burn Proof technology and let a buffer-underrun occur every 8MB? Heck, half of the time you'd be writing less than 8MB anyhow. Still, I have to say, the CD-ROM format (or what little I understand of it) seems to be the most (needlessly) complex format I've ever seen...

Why not use the same technic as used in printer. A simple buffer, an extra memory device, let's say 786MB. First you fill the device with the data you want to burn on cd and give a trigger when the actual writing process can start.

Correction 4x speed is 4x150 kb/s = 600 kb/s
Also some older drives can burn at single speed my (old plextor 24/10/40. for instance)

600KB/s that must be both read and written.

I doubt if single speed is even attainable by MSX. Maybe if done from memory, but otherwise...

I must say though, apart from the cool factor, I don't see the point...

Fortunately, it's a little less: 4 x 150 = 600kB/s. But it's probably still too much. Iirc MegaSCSI can reach that amount of data traffic (in burst mode) on an MSX turboR. But one would surely wish for a buffer-underrun protection service then

[edit]Sorry, I just saw the other replies -- ignore this one [/edit]

Webmouse: you mean there must be an external interface for that? You could fill the write buffer of the CDRW, but I don't think that'll suffice

Would be cool to have, yes, but I think it's a pretty expensive solution, I suggest utilising the buffer underrun protection would be the best choice.

if you have a TR and a mega SCSI then you come close to 512 KB per sec or 800KB per sec
its just to less speed to burn cd's.
but why you need a cd burner @ your MSX?
i have a SCSI interface with 2GB hd around 64 partitions of 32MB thats my msx Mass storage device....
and i use only 1GB.
but ince i have CF from sunrise MY hd is stored save in my closset

Exactly, it wil be a costly device. But for the 'real' MSX die hards price is not an issue .
I was just wondering if it could be/has been done.
