*ALL RAM* BBS for Arduino
by Allen C. Huffman ([email protected] / www.appleause.com)
This is an experiment to see how easy it is to translate Microsoft BASIC to
Arduino C. The translated C code is incredibly ugly and will be disturbing
to most modern programmers. It was done just to see if it could be done, and
what better thing to translate than a program that was also originally done
just to see if it could be done -- a cassette based BBS package from 1983!
About the *ALL RAM* BBS:
The *ALL RAM* BBS System was writtin in 1983 for the Radio Shack TRS-80
Color Computer ("CoCo"). At this time, existing BBS packages for the CoCo
required "2-4 disk drives" to operate, so *ALL RAM* was created to prove
a BBS could run from a cassette-based computer. Instead of using floppy
disks to store the userlog and message base, they were contained entirely
in RAM. The in-memory databases could be saved to cassette tape and
reloaded later.
The original BASIC source code is included in comments, followed by a very
literal line-by-line translation to Arduino C. Remember, it's not a rewrite
in C -- it's BASIC code done in C.
Be warned. There be "gotos" ahead!

2013-04-02 0.0 allenh - Initial version with working userlog.
2013-04-03 1.0 allenh - Message base working. Core system fully functional.
Preliminary support for Arduino Ethernet added.
2013-04-04 1.1 allenh - SD card support for loading/saving.
2013-04-05 1.2 allenh - Ethernet (telnet) support.
2013-04-06 1.3 allenh - Cleanup for posting to www.appleause.com
2013-04-09 1.4 allenh - Fixed a bug with INPUT_SIZE and input.
2013-04-12 1.5 allenh - Integration with new Telnet server code, misc fixes.
2015-02-14 1.6 allenh - Adding some "const" to make it build with 1.6.0.
