IDE64 Peripherals

IDE64 and C64 peripherals

ETH64II the Ethernet card

ETH64II is a device for IDE64 which allows connect C64 into (TCP/IP) network. The device is based on LAN91C96 chip.
Unlike the CS8900a chip used in similar embedded Ethernet card solutions the LAN91C96
  • has greater internal RAM (6kB)
  • dynamic memory allocation
  • supports IRQ in 8bit mode
  • direct register addressing

DUART - dual port RS-232 interface for IDE64

DUART card is a data communication device based on 68C681 compatible chip that provides two fully independent full duplex asynchronous communication channels (RS-232). The card is industrial designed and allow user to select the 23 different standard bit rates from 50 to 115 200 bps. It can be used for all standard serial RS-232 devices. DUART is supported in the IDE-DOS to provide serial PC-Link.
