cc65/ip65

IP65 - a TCP/IP stack for 6502 based computers

IP65 consists of three parts:

• A TCP/IP library to be used by 6502 asm programmers using the ca65 macro assembler
• A TCP/IP library to be used by C programmers using the cc65 6502 C cross compiler
• Several ready-to-run TCP/IP programs using one of the libraries

All three parts are available for three 6502 based target systems:

• The C64
• The Apple II
• The ATARI (XL)

IP65 requires Ethernet hardware. There's no support for TCP/IP over serial connections whatsoever.

On the C64 there are two supported Ethernet devices:

• The RR-Net - emulated by VICE
• The ETH64

On the Apple II there are three supported Ethernet cards:

• The Uthernet - emulated by AppleWin and GSport
• The Uthernet II - emulated by AppleWin
• The LANceGS

On the ATARI (XL) there is one supported Ethernet device:

• The Dragon Cart - emulated by Altirra
