[Coco] Drivewire and ADOS...

Chris, have you done any work in MS Visual C++?

I do most of my code in C, actually.  At other times, C++, Objective C (there's 
a bit of a theme here I guess), Java, Forth, Scheme, Perl, Python, and -- well, 
some others. :)  What assembly I've done is often inlined into C code, actually.  
Last time because I wanted to take command-line arguments and convert them into 
an arbitrary function call to an arbitrary dynamically loaded library.  C 
doesn't have a built-in facility for doing that but it's easy to arbitrarily 
construct a standard call on the stack with a few assembly operations. ... but 
as for Java, I have done a few personal projects with it and worked on probably 
two projects for a small commercial software house that used it.

No, it's not really a language for the CoCo, though there are possibilities.  
Google tells me the CLDC requires only about 160k of memory at a minimum.  There 
are some assumptions built in about the code-size of the interpreter, so you 
could perhaps get by with less.  It also "requires" a 16 bit processor, but I 
suspect what they really mean is that you must be able to perform 16 bit numeric 
operations.  It seems feasible to cram a CLDC/MIDP1.0 (I say 1.0 because they 
didn't add floating point math until 2.0, though if it did support 2.0 you could 
run Angry Birds) system in 512k of RAM on an upgraded CoCo 3, emulating the 
16-bit numerics and using drivewire for its required network connection.  Of 
course this would be a huge project of limited usefulness, and probably isn't 
the right way to get anything on the CoCo, but it would be hilarious if it could 
run Java code. :)
