In my other life, I run the Low End Mac site <http://lowendmac.com/>. One
of my favorite sections, although not well received by some, is the Road
Apples section. Here I take a hard look at some dumb Apple designs. The
LC, LC II, Classic II, and Color Classic are traditional favorites in
this category for:
1. The 10MB RAM ceiling.
2. The 16-bit memory bus with a 32-bit CPU.
3. And a 16-bit PDS.
To add insult to injury, the Classic II is missing the PDS.
Okay, back to BSD.
