Btw, when compiling in large memory model via
fpc -Wmlarge
the pointer errors when compiling keyb are gone. There are some 20
remaining compile errors. Perhaps these can be solved.

For something like this "FarPointer(@Buffer)" I get the following
error message:
"Error: Illegal type conversion: "Pointer" to "FarPointer""
My opinion is that this should be supported by the compiler, because
it is well defined for the small memory model I am working in.
I looked into the keyb source code and tried to compile it with
FreePascal. One problematic line is for example:
PWord ( ptr(m-1,1) )^ := m; { make it self-parented }
Here, Ptr emits a far pointer, and PWord would cast this to a near
pointer. FreePascal complains about it.
BUT the following at least gets accepted by the compiler:
type PFarWord = ^Word; far;
PFarWord ( ptr(m-1,1) )^ := m; { make it self-parented }
This converts it to a typed FAR pointer, which than can be de-referenced.
What is more concerning are error messages like:
"Warning: Use of +offset(%ebp) is not compatible with regcall
convention", since there is not a trace of 32 bit instructions in the
code.
