Hi there,

I know, I am very adventurous... I have tried to use a different font than 
computer modern :) (actually I have used some standard-postscript fonts 
with context before...)

So I have tried to use the installed times-roman (the urw variant) and the 
vf's that come with the tetex distribution in T1 AKA ec encoding. So there 
should be a simple mapping between times-roman and ptmr8t. The rest should 
be done in the dvi driver. 

That is what I have tried: (I am using times here, because I know everybody 
has it).
-----------type-t1times.tex--------
\usetypescriptfile [type-buy]

\starttypescript [serif][t1times][ec]
 \definefontsynonym [Times-Roman]      [ptmr8t]  [encoding=ec]
 \definefontsynonym [Times-Italic]     [ptmri8t] [encoding=ec]
 \definefontsynonym [Times-Bold]       [ptmb8t]  [encoding=ec]
 \definefontsynonym [Times-BoldItalic] [ptmbi8t] [encoding=ec]
 \definefontsynonym [Times-Slanted]    [ptmro8t] [encoding=ec]
 \definefontsynonym [Times-BoldSlanted][ptmbo8t] [encoding=ec]
 \definefontsynonym [Times] [Times-Roman]
\stoptypescript

\starttypescript      [serif][t1times][name]
   \usetypescript     [serif][fallback]
   \definefontsynonym [Serif]    [Times-Roman]
   \definefontsynonym [SerifBold][Times-Bold]
\stoptypescript

\starttypescript [MyTimes]
  \definetypeface [mytimes] [rm] [serif] [t1times] [default] [encoding=ec]
\stoptypescript
---------end type-t1times.tex------------

------------timestest.tex ---------
% output=pdf
\mainlanguage[de]
%\enableregime[il1]
\setupencoding[default=ec]
\usetypescriptfile[type-t1times]

\usetypescript[MyTimes]
\setupbodyfont[mytimes]
\starttext
ä\"a "a ß \"s 
%\showfont
\showcharacters
\stoptext
-----------------timestest.tex

Here is a description of my output:
first line: äa a SS s (both a and last s with a bar in the middle, but the 
"a-bar is a bit lower than the "s .)

then there is a line 'default ptmr8t at 12.0pt: composed bottom char raw'

after that a lot of very weird accents and Chars and black rules...

There is obviously something going wrong. But what? There is for example 
'textgrave' mentioned in the first position, which is in texnansi pos 18 
(decimal). And in the pos 18 in ec encoding, there is quotedblleft, which 
is shown in the \showcharacters output. So this seems to be a bit 'correct'

Don't dare to uncomment \enableregime[il1] -- the first line gets even 
worse :)

And - don't uncomment \showfont! You can't say you haven't been warned :)

BTW: I am using:

This is pdfeTeX, Version 3.14159-14h-released-20010417-2.1 (Web2C 7.3.3.1)
entering extended mode
(./timestest.tex{/usr/share/texmf/pdftex/config/pdftex.cfg}
