Hi Duke, I'm going through a MUPID BASIC book to see if there is usable hardware information. MUPID apps ("telesoftware") could be transferred as BTX page payloads, and the book has this to say:
"BTX is a slow medium with its transmission speed of 1200 Baud. Even with "normal" pages which only contain text or graphic information, this can lead to nervous traits like drumming your fingers, chewing your fingernails or a change in smoking habits. This is also true for telesoftware. As tsw is loaded into RAM and there is no visible action on the screen, a phlegmatic character is needed to survive the loading time of a long program unscathedly."
