Hi Readers,                               (Update Jan 19)
        Here is the current list of the ever expanding TECH bull collection.
Not all 409 buls (inc this 1) will be on your local BBS yet, but they will be
soon. Three bulletins are sent each day, so the whole set is repeated about 3
times a year. Some files are large & not split up. Most BBSs use a bulletin
timeout of 1-3 months, so you may have less than 100 bulls on it.

The files are often updated, as I Rx feedback on them etc. The date of the last
significant update is on 1st text line of each bull, so it can easily be
compared (download & abort "A") with your own file to see if you need the
update. The collection is not numbered as this would complicate new files in
the subjects etc.

Most of the files use the very efficient 8 Bit ASCII graphics set, (code page
437 or 850, "Terminal Font").

If you like reading these buls please reply, any comments/updates welcome.

Copyright is waved for all my bulls, as they are for the benefit for all, but
please leave the callsign on the work if you publish it elsewhere.

Most of these buls, have been repeated on club websites (e.g. in Spanish) in
far less efficient formats like PDF, BMP, PCX, GIF, JPG. (not really suited to
packet) see www.theskywaves.net or do a search on G8MNY. But the purpose of
them is to improve the content of Packet Radio!

Try writing your own buls & make packet radio more interesting! See my "Making
ASCII diagrams" bul on how to do it.

If you have problems viewing or printing the 8 bit ASCII Graphics, see my bul
"Y Extended ASCII Graphics" for compatibility solutions on most platforms.


Why Don't U send an interesting bul?
