Bobbi's Fork of IP65

I have made the following changes:

DATE65

• Load timezone information from TZONE.TXT configuration file, rather than hard-coding.
• Automatically determine if it is DST or not (using North American rules) and choose timezone accordingly.
• Support for ProDOS 2.5 extended date format.

The following programs are completely new:

• POP65 is a Post Office Protocol version 3 (POP3) client for the Apple II with Uthernet-II card.
• EMAIL is a simple user interface for reading and managing email. It works together with POP65.
• SMTP65 - not started this yet!

The original README.md follows ...

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 LANceGS
• The Uthernet II

On the ATARI (XL) there are two supported Ethernet devices:

• The Dragon Cart - emulated by Altirra
• The Dracarys
