Imm trying to get system 7.6 on my 8x cdrom drive on a powerbook 1400cs but i cant burn the cds at 8x using my macbook air. How can i burn cds at a lower speed?

You could try to use an external cd burner that writes at 8X, or use another Mac that has a 8X CD burner installed.

Burn at whatever. Your 1400 will only read at 8x, whatever speed it was written at. The better the dye, the more likely the Teac drive in the 1400 will read it, so avoid bargain basement discs. Use Roxio Toast and you can select the burning speed right down to 1x.

As long as you aren't running Catalina, you can use older versions of Toast.

What about burning with Windows and IMGBurn?
If your PBs CD drive is already degrading, burn at slowest possible speed.
CD blanks today of are of not so good quality regardless whats printed on the box.
Mostly from CMC on my side, useless for AIFF CD-ROM already.
If possible look for some pristine Kodak Gold Ultima, as those do still are good to burn after all the years and can be read by troublesome hardware, if the laser diode is not totally dead.

I dont really know if its dead since theres no OS on the powerbook 1400. The performa 6116cd is 2x cdrom

Burn/write speed has nothing to do with read speed.
You can burn at 16X with one computer and read at 2X on an old Mac external CD-ROM.

Sort of... I used to have to write at a slower speed to make discs that would be readable on older 2x CD-ROM drives. Once the write speed went past a certain threshhold, the older drives would fail to differentiate between the pits and the surface. This is both drive and media dependent though.

How did you burn your System CDs? Do they work (boot) with other devices?
When not a single CD-R is working in the PB, the CD-ROM´s laser diode may be worn out.
I would really give the Kodak CD-R Utimate a go. If any CD-R is still read, thats the one.

The PowerBooks CD drive itself should be replaceable, Apple seems to have used TEAC drives back in the days.

If you wish, send a picture of your CD drive´s connector and I´ll have a look in my crap box.

Do you have the floppy drive plug in as well? Does your PB boot from floppy?
As a last stand, you might remove the PBs HDD and connect it to another Mac (emulator) to install System 7.5.3 (for every Mac) onto the internal hard disk.

You will know that you have to press Command-Opt-Shift-Del keys to boot from CD. Wink

Just hold the "C" key down at startup on most Macs to boot from CD.

If you replace the 1400's CD drive you need to make sure it is set as master IIRR. I understand that a lot on eBay are factory set as slave. That isn't necessarily straightforward and might need getting the soldering iron out.

Also, the azimuth setting on the 1400 was forever going out of alignment, so for a quick fix before junking the drive, you can try adjusting the screw on the laser arm up to a quarter turn up or down and see if that improves matters. If it reads pressed but not burnt CDs then you probably have a clapped out laser.

Exactly what I was thinking Troyd, any replacement drive will have to be set to Master with the oldies.
Had the same issue with a Toshiba Portégé recently.
Too bad soldering Pin47 to ground (Pin45) is not always that easy as there may be SMD stuff very close to the ATAPI-50 connector. In such cases fumbling in a tiny copper wire on the back of the connector may be the way to go.
The procedure is described here in German, but the pictures show the idea good enough.

I do have a working TEAC drive in my crap box, which I would gladly donate to papichulo if his CD ROM already has the ATAPI-50 connector.

For burning HFS CD images to CD-R on a Mac (up to Mojave) LiquidCD is a possibility.
(Simply burning from macOS Finder should be as good, though.)
I feel that IMGBurn with Windows does the better job, but some here will not own a Windows rig and dislike the idea of setting up a virtual machine e.g. for Windows XP.

I believe the 7.6 CD has a complete floppy set on it if you have a way of making floppies.
I could burn you a set. I assume you have the 1400 Floppy drive?
Note: The 7.6 Drive Setup was bad. When you get things running the hard disk driver should be updated with the 7.6.1 Drive Setup.
Don't forget the 1400 has SCSI if you can get access to an external CD drive.
I've got three or four lying around.
