<DIV><FONT face=Arial size=2>Well, I think I identified one problem. I took what
should be valid 6809 code and ran it through an assembler (with emulator) that I
found. I believe that I have the correct approach (similar to what you did) but
my loaded code wasn't correct. Actually, that's probably a good thing because
that is easy enough for me to fix. I was hoping to lift a RAM test routine right
from Qix, but it's not so hard that I couldn't just re-write it
myself.</FONT></DIV>

<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Has anyone done this before? Building a
compiled program, loading it byte by byte into memory, and then doing Run
UUT? I was playing around with this last night, but I couldn't get it to
work. (6809E based system). Could be lots of things at this point, and I'm
going to review the Troubleshooter documentation, but I thought I'd ask.
Talk of testing RAMs made me think to try a few tests to see how easy it
would be to build a "fast RAM" tester. I just took a snippet of code from
the Qix self-test and wanted to run a modified version of that. However,
even a simple test where I'm writing to a specific address did not seem to
work. Been a looong time since I wrote assembly, and I've never had to
bother looking at the generated op codes! The code was relocatable
code.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>On a related note, it appears that it's
possible to write some z80 code that could be executed by the 9010A base
unit. You can't use the Fluke compiler, however, because you'd need to have
a slightly different record structure for the program. This is part of the
reason that I was asking about interest level in a new compiler. That, and
the fact that there are gaps in the programming language that might be easy
to fill.</FONT></DIV>
