The original Apple CD-ROM Player 300e. In good
optical and technical condition - a collectors
item!
The 300e CD player from Apple sets the standard
for others to aim at with its double-speed technology,
a speed select switch, a reasonable list price
of $599 (back in the 1990s), and support for multi-session PhotoCDs
along with three other formats I'm unfamiliar
with, CD-ROM XA (which apparently requires some
extra hardware to play compressed audio), CD+G,
and CD+MIDI. It of course reads all the ISO 9660/High
Sierra and Macintosh HFS discs that the old (and
still available) AppleCD 150 can read. The drive
has an average access time of 295 milliseconds
in double-speed mode, in which it can also transfer
300 KB of data per second.
Interestingly the AppleCD 300 appears to have
two modes. In mode 1 the drive can read 656 MB
per disc, and transfer data at either 150 KB/second
or 300 KB/second (working at normal or double
speed). That jives with the little I know about
CDs. In mode 2 the drive can read 748 MB per disc,
and transfer data at either 171 KB/second or 342
KB/second. That's weird. It turns out that these
modes are standards and almost all drives support
both modes. Mode 2 discs store more and read faster
because it has less error correction (not a problem
for audio and fast animation, where a missed bit
wouldn't matter), but almost no discs use the
mode 2 format. Many thanks to Cary Lu, who solved
this mystery by quoting from the fourth edition
of his excellent book, "The Apple Macintosh
Book," (ISBN 1-55615-278-7, $24.95 from Microsoft
Press).
