Hi Readers, (Update Feb 22)
Here is the current list of the ever expanding TECH bul collection. Not
all 427 buls (inc this 1) will be on your local BBS yet, but they will be soon.
Three buls are sent each day, so the whole set is sent nearly 3 times a year.
Some files are large & not split up. Most BBSs use a buletin timeout of 1-3
months, so you may have less than 100 of these buls on the one you use.
The files are often updated, as I Rx feedback, improve the content or spot
errors on them etc. The date of the last significant update is on 1st text line
of each bul, so it can easily be compared (download & abort "A") with your own
kept file to see if you want the update. The collection is not numbered as this
would complicate new files in the subjects etc.
Most of the files use the very data efficient old 8 Bit ASCII graphic set,
(code page 437 or 850, "Terminal Font").

If you like reading these buls please send a reply, any comments/updates
welcome.
Copyright is waved for all my buls, as they are for the benefit for all, but
please leave the callsign on the work if you publish or refure it elsewhere.
Many 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) For PDFs 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?
