SebRmv Posted February 19, 2008 Share Posted February 19, 2008 (edited) Hello, I can't remember how to boot a CD on a Developper console equiped with the Jag CD developper kit. Can anyone here recall me what to do? Should I plug the interface cable? Is there something special to do? (press C at boot time...) Thanks! PS: for the moment I get the picture indicating to plug the power cord of the CD unit whereas it is already plugged!

Plug the interface cable (grey connector into black plug) Then boot while pressing C And this works Quote Link to comment Share on other sites More sharing options...

And hold 'A' down if you want the stub to load in DRAM instead of on the Alpine. Quote Link to comment Share on other sites More sharing options...

Symmetry of TNG Posted February 20, 2008 Share Posted February 20, 2008 hmm.. do you own a cd dev kit? with the rainbowribbon & falcon converter?...cool =) cant remember i read anyone having such... but if someone do I hope he will help you sorry i cant be of any help :/ And i hope it didnt just break... that'd be a bummer /Sym Quote Link to comment Share on other sites More sharing options...

belboz Posted February 20, 2008 Share Posted February 20, 2008 I have a full developers unit from an ex-atari developer. The CD unit has a gray cable coming out of it that goes to a little PCB that has 3 connectors on it. You have to have it plugged into one specific connector when you just want to use the JagCD as a normal JagCD (obviously it still has the dev bios in it so it will boot unencrypted cd's). Without this cable being plugged in you get the power issue your seeing. The pcb has two connectors going straight up and one at a right angle. The right angle is for connecting to the Falcon. The straight up connector on the other end is for normal JagCD usage. The middle straight up connector is for when you have the Falcon connected to the other cable.

I didn't know these. that's basically what I did yesterday by pure coincidence I don't understand why it does not work anymore today.

atarifan49 Posted February 21, 2008 Share Posted February 21, 2008 And that connection to the Falcon must go thru a DSP interface board and not straight to the Falcon. The small adapter board provides loopback connections to allow the CD unit to function. Glenn Quote Link to comment Share on other sites More sharing options...
SebRmv Posted February 21, 2008 Author Share Posted February 21, 2008 (edited) Do you have the pinout of the small PCB board so that I check why it does not work in JagCD mode? Edited February 21, 2008 by SebRmv Quote Link to comment Share on other sites More sharing options...
Symmetry of TNG Posted February 26, 2008 Share Posted February 26, 2008 Seb> Sweet! =) And that connection to the Falcon must go thru a DSP interface board and not straight to the Falcon. The small adapter board provides loopback connections to allow the CD unit to function.Glenn hmm.. when skipping through this info in the devmanual some 5 years ago I got the feeling you just plugget that "rainbow coloured" cable to that "2-connectors in straight angle to pcb" and that Into the DSP port on the falcon... I reconed the dsp is powerful enough to handle the data and emulate a 2x cd stream from a scsi drive... Do you mean there have to be yet another DSP board inbetween cable & dsp port on falcon? Actually if anyone have a picture of such a setup (complete on jaguar side & perhapps without the falcon, but with the dsp connector in the end of some cable?) I for one would be interested to see it, to see what parts were actually needed.. cheers /Sym Quote Link to comment Share on other sites More sharing options...
SebRmv Posted March 2, 2008 Author Share Posted March 2, 2008 Could it be one of the engine of the CD mechanism? Quote Link to comment Share on other sites More sharing options...
SebRmv Posted March 8, 2008 Author Share Posted March 8, 2008 (edited) Could it be one of the engine of the CD mechanism? Hi, I finally changed the CD mechanism because I suspected one of the engine. Unfortunately, it has not changed anything. However, while unmounting the JagCD, I noticed that two wires of the multicolor cable going out from the CD unit were hanging (not soldered anywhere). Is it normal? Has anyone have the wiring of this multicolor cable so that I can check that? Thanks Edited March 8, 2008 by SebRmv Quote Link to comment Share on other sites More sharing options...
