The Part-Time BBS was the longest running Atari 8 bit BBS in the 216 Cleveland Ohio area code. It was originally online from 1985 to early 2000.
On December 23, 2017, Part-Time returned online via telnet. The version that you can now telnet to was pieced together with backup floppy disks from 1990.
The BBS includes restored messages/message bases from 1988 through 1990, some restored file sections, and online games.
For best results, log in with an Atari 8-bit or a telnet client that supports ATASCII (Atari Mode). One such client is Syncterm. Syncterm is available for Windows, Linux, Mac OS/X, etc.
You can download Syncterm here.
Part-Time's telnet address is: ptbbs.ddns.net port 8000.
