I don't recall there being any extensions that were CD related. Would
they have come with the default OS install?
And how does an extension affect the ability to boot from the CD? I
would have thought that the boot ROM code would have to know about
the CD without the aid of an extension...

Yes, I'm using the funny Apple SCSI cable. It is the same cable/setup
that works fine with the PB 150. Perhaps the 600e is just too new for
the 540c, but the PB 150 came out in 1994 and the PB 540c was certainly
in about that same time frame. The AppleCD 600e came out in 1995, so
maybe that is the problem. I guess I should pick up an AppleCD 300
to see if that works better.

One 540c came with 7.5 installed and the other with 8.0. I have not
upgraded either OS, primarily because of the lack of 600e support.

How does the working CD solve my problem? I realize that I will be
able to write a large file on my PCs CD-RW, but will the MacOS be
able to read the file structure? And if it does, will it handle
the file type problem correctly? The new FreeMidi version is a .hqx
file. Will the OS know what to do with that or will I have to get
some Stuffit type thing to take it apart?
This is exceedingly frustrating, especially as Macs are touted as
being straight forward. I have to admit that in my experience over
the years, they have never lived up to that name, but then I guess
I try to do things which are less than mainstream.
Thanks for your help!
