Note that the sources you mention do not have a real working CDTV driver in them. They dont actually talk to the CDTV hardware but create a CDTV shim layer for a cd.device which wasnt for the original CDTV. It was for the CDTV-II.dalek wrote: 23 Jul 2019 15:40 EDIT: those "commonly available" files also have a cdtv.i version for people to find which would probably do the job.

DO NOT USE MOBILE / CGNAT DEVICES WHERE THE IP CHANGES CONSTANTLY!
At this time, it is unfortunately not possible to whitelist users when your IP changes constantly.
You may inadvertently get banned because a previous attack may have used the IP you are now on.
So I suggest people only use fixed IP address devices until I can think of a solution for this problem!

Re: CDTV Resourced Project
If the source/header-files available was for the CDTV-II, could it perhaps be modified to work on a CDTV upgraded with an internal SCSI-CDROM drive?
I personally think it would make good sense to try and code a driver for the CDTV where we finally can get rid of the old drive and upgrade them with newer and better alternatives. The CDTV-II could be using a newer version of the custom CD-ROM interface, only all too common in the early stages of consumer CDROM's
A CDTV with a 12x SCSI CD-ROM and upgraded processor board. Now, wouldn't that be something?

Re: CDTV Resourced Project
Really that just needs you to implement the API published in the CDTV.H which has been public for 30 years. Im sure if it was easy it would have been done.

Re: CDTV Resourced Project
It would make most sense to implement a cd.device for IDE cd's (or find/modify one if it already exists) and then marshall requests via cdtv.device to the new device.
Personally I think Amiga device drivers are nasty over complex things. Not a fan.

Re: CDTV Resourced Project
Agreed. However, we should just all keep in mind how unique the OS was for the time (start 80ies), and the original developers did a good job in my opinion, with limited hardware resources and not a lot of reference platforms/systems from which to seek inspiration. Same goes with the CD, which for many was a real first. Around the same time, I bought a Sony CDU-33a drive with pop-sled for my developer Am386 PC, complete with custom ISA interface board. Piece of c... it was.

Re: CDTV Resourced Project
I don't know any other attempt to fix problems. I think that it is because sources are lost?

Re: CDTV Resourced Project
Ok so to be clear i never tried to update the driver code. I got my CPU card to patch rom locations on the CDTV.utri007 wrote: 03 Dec 2019 18:49 I don't know any other attempt to fix problems. I think that it is because sources are lost?
The code is supposed to produce an exact binary until every single part of the driver is understood and decoded.

Re: CDTV Resourced Project
Don't worry. Could you write summary, what prevents Amiga accelerators work with CDTV.Ok so to be clear i never tried to update the driver code. I got my CPU card to patch rom locations on the CDTV.
The code is supposed to produce an exact binary until every single part of the driver is understood and decoded.
If I have understand right, CD.device thinks that all memory all DMA capable? And tried to read / write with physical CD-drive? Same with SCSI hard drive?
