Assuming that the 8808 you mention is in fact the 8088 in the P.C. etc.
then there do exist programs for changing 8080 code into 8088 code (That's
how Micropro got a version of Wordstar out so damn fast: it's just the
8080 version in drag). The only risk using it on 8085 code is those two
odd instructions 'rim' & 'sim' (hex 30 & 20, I can't remember which is
which). Other than that the 8085 is code compatible with the 8080. I'd
start by getting hold of the people at Microsoft. Alternatively if you
can get hold of an 8088 assembler with macroing capabilities comparable
with RMAC by Digital Research you should be able to do it with macros.
(Believe it or not, I've seen a full 8080 assembler written using macros
on a 68K box) As for writing your own, it takes about six weeks to get
an assembler going from a cold start, all you have to do is to directly
translate the 8080 mneumonics into the appropriate 8088 byte values.
