Most of the TECH buls use 8 bit graphics. To make your own diagram here are
some tips.
TEXT EDITORS
The keyboard only does a few of the 128 extended code graphic characters, the
full set are normally entered by holding down the ALT key & entering the 3
digit number into the number keypad, this works in most text (not document)
editors. (MS OS, Other OS platforms are different!) Also don't use justify or
variable spacing in the editor / viewer!
Try these for yourself.
Ú¿
[] = ÀÙ, | = ³, - = Ä, Ts = Â ´Ã Á, + = Å Ohm = ê, Degree = ø, +/- = ñ
ALT 218 191 179 196 194 180 195 193 197 234 248 241
KEY 192 217 (not all Code/Pages)
In a good editor you will find a list of all the characters in the help screen.
Print these out if you can. Some editors also have block cut & past (not
paragraphs) & this is a very useful feature for moving & copying.
GRAPHICS & CHARACTERS
Here are some Characters & 8th bit Graphics mixed & how they look together.
ALT
045 - (Hyphen) Do not join up --³-³
095 _ (Underline) Only partly joins ___³_ (can't use space above!)
196 Ä (Graphic) Joins up OK ÄÄ´ (OK to underside of undeline)
124 | (Bar) Do not join up | (some Fonts have broken bar)
186 º (Graphic) Joins up own set ĺÄ
061 = (Equals) Do not join up == ³=Ä
095_046.044,045-039' Rising graphic '-,.__.,-' (eg detailed Graphs, Circles)
How viewable the results are of mixing them, will depend on your font & to some
extent the video card to.

Often there is not enough detail for precise component graphic symbols, but to
a good engineer these graphics are good enough. (clearer than bought Photo-
copied Diagram!)
As with any text composing this may take a while, so do save it as an ASCII
(.ASC or .TXT) file often (possibly as a .BAK file as well!).
Try to can make the diagram size less than 79 characters wide by 23 lines high,
as this fits most viewers with room for their control bars etc. & should stop
auto wrapping of carefully spaced diagram when sent over packet. This size
restriction may mean splitting the diagram up into functional blocks, giving
you the option to describe each part as you go. Not normally possible with
other drawing systems!
Once you have finished drawing your diagram, go down the right hand side &
remove all the added spaces at the end of line as these are not needed.
If you are describing the circuit then use component Numbers, not values & make
a component value table....

3 2R 22n 1mH
4 220K 3n3
5 100K
6 1M
If it is for a BBS bulletin, I use .BUL as a file name extension & also add
standard headers & tails etc.
The result should be a VERY compact ASCII file ideal for Packet & easy for your
SYSOP to check & vet before releasing. And it will be quick & easy to read on
many system platforms & in any language....
