Rob O'Donnell writes "Distributed by Pace Microsystems (Bradford, UK) for use with their 'Nightingale' modems. (So not sure I can provide source or anything, but might be able to check.) Was inspired by TBBS, for the Tandy, which was used by most of the BBSs I called at the time, but optionally provided 40 column Colour and block Graphics using the videotext graphics capabilities of the BBC micros. Used to run my own BBS on this, of course, but was used by many others in the UK, and in turn inspired a number of copy cats, including NBBS (Jon Freeman). Was partially compiled and compressed, and ran completely in memory on the BBC (about 20-odd K) and used floppy discs for data access only."
