How to open CD drive tray from the OS? 8.1


Recommended Posts

Hi all,

 

I upgraded the 2x speed caddy drive in my 840av with a Plextor PX-40TSi. Working great with a patched Apple driver (https://www.macintoshrepository.org/23007-apple-cd-rom-software-5-3-2-5-4-2-)

 

But of course, the old drive didn't need to be opened as it was a caddy system. Once I put the case back on the system it covers the cd tray open button. I looked for various solutions but they all seem to be for system 9+ and ppc only. Does anyone have suggestions for my system? 840av on System 8.1.

 

Thank you,

Will that work on 68k Macs? Or with OS 8?

 

The real 1993 solution to this would have been to replace the CD bezel with one that had a button for trayload CD drives. (or run with the CD-ROM bezel removed.) Such a bezel should exist, although you may end up with one from an 8100/8200/8500/9500, just depending.

I recompiled the Eject code I linked above under CW Pro 4 for 68k.  I don't have a 68k mac with a CD ROM drive to test it on but I mean it didn't crash my emulator or my currently accessible 68k mac.  So this comes with all the caveats about running random code off the Internet, but might be worth a try?

This works in my Quadra 950 with an Apple tray loader (OS 8.1) The tray does need to be closed by hand, but it will eject regardless of whether there is a disc inserted. Nifty!

Cool!  I'll do a version with the proper icons and stuff in, then :-)

Very cool, glad to see it already on macintoshgarden too. Thanks for doing this!

You are very welcome!  It really was about 15-20 mins work once I'd remembered how to use CodeWarrior.

This is a neat modern convenience that I'm glad to see has finally been backported to 68k!

I honestly don't know why the "stock" build isn't 68k/FAT, there weren't any actual code changes needed at all!
