Thank you Wolfgang for the reply. If I compile your code then I get

! Undefined control sequence.
l.20 \defineconversionset
                          [frontpart:pagenumber][romannumerals][]

and if I comment this line, I get

! Missing number, treated as zero.

and if I comment   \setcounter[userpage][1]

then
- page 4 has a header line, which I don't like
- page 7 or 11 has not the marking Knuth respectively Zapf
- useless page 13 at the end of the document

I guess that's because I don't use the latest version. I use 
context_2012.05.30.2012061,
TeXExec | version 6.2.1 - 1997-2009 - PRAGMA ADE/POD


I finally came up with the following code, which does it for me.

\setuppagenumbering[alternative=doublesided,location=]

\setupheadertexts[]
\setupheadertexts[\setups{text a}][][][\setups{text b}]

\startsetups[text a]
     CHAPTER \getmarking[chapternumber]:
\expanded{\uppercase{\fetchmark[chapter][first]}}
   \stopsetups
\startsetups[text b]
     \getmarking[section]
   \stopsetups


\setupfootertexts[][pagenumber]

\setupheader[text][after=\hrule]

\setuphead[chapter][header=empty]

\setupsectionblock[frontpart][
before={\setuppagenumbering[conversion=romannumerals]},
after={\page[yes,header,right]}]
\setupsectionblock[bodypart][after={\page[yes,header,right]}]
\setupsectionblock[appendix][after={\page[yes,header,right]}]
\setupsectionblock[backpart][after={\page[yes,header,right]}]

\starttext

\startfrontmatter
\startstandardmakeup
\title{title}
\stopstandardmakeup
\completecontent
\stopfrontmatter

\startbodymatter
\setuppagenumber[number=1]
\chapter{body}
\dorecurse{10}{\input knuth}

\stopbodymatter

\startappendices
\chapter{appendix}
code
\input knuth
\stopappendices
\page[stop]
\stoptext
