SCSI: DB-25 Serial Ports: 2 Sound Output: stereo 8 bit. ADB: 2 Ethernet: none Machine Gestalt ID: 83 PRAM Battery: 3.6V lithium (Maxell ER3S, Radio Shack 23-026) Minutiae: The Color Classic II is only sold in Japan. Most of Apple's newer computers are capable of using either symmetric or asymmetric 16Mb chips. However, the Color Classic II requires symmetric memory. This is only an issue when dealing with SIMMs which use 16Mb chips. SIMMs built with Symmetric chips are indicated by an "L" suffix on the part number. Serial Port with the phone icon supports synchronous modems, however full handshaking is supported on the output, and not the input. Has 1MB ROM and a 1.44MB SuperDrive. Contains an 32-bit 030 LC Processor Direct Slot (PDS).
