Hi Readers, (Updated Sep 17)
Here is the current list of the ever expanding TECH bull collection.
Not all 404 bulls (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").
