Back in 1993 or 1994 I wrote a hypertext browser for the TBBS system. I advertised in Boardwatch and sold maybe two copies. It used a subset of HTML, and spoke to both ANSI/VT-100 and RIP systems.
Anyway, here's the source code, without warranty or support. If you can use it, that's great. I'll help where I can, but it's been literally years since I've looked at it. Have fun!
