C*Base v3.3.8+ updated by Holy Moses and Released on July 1st, 2020.  Here's a quick overview of the improvements:

- Up to 38400 bps
- ":" in bbs-list allowed for host-#´s
- Colored, more cooler directories
- Turbomode 48MHz supported by enablebit
- Directories/userlist with autopause
- Visible autopause "on" or "off"

This version of C*Base will run out of the box on the Ultimate64 with SwiftLink emulation and firmware v1.34 (and newer I assume).  Note the support for 48Mhz turbo mode!
