Hallo Spiro,

I can generate a COM when org = $0100. But then all JMPs and CALLs are
So I have to set the org of the file to $8000 as it is a 32 KB ROM. Then
EXE2BIN says it cannot create a COM because of the wrong address. Telling it
to create a BIN instead, it says it has insufficient memory ????

> An EXE file should not have this behaviour, DEBUG should load it

It does indeed. After "debug PC20.EXE" and "d" after the "-" prompt, it
neatly starts with:
 182C:8000  EB 02 ....
which is absolutely correct. But for one or another reason it saves from
182C:0100 on in this case. So I changed CS to 201C in this case and now it
saves the right part.

I still encounter one small problem: I loose the very last two bytes
somewhere in the proces. But I can live with that.
