  <DIV><FONT face=Arial size=2>There are samples of&nbsp;loading &amp; running
  UUT code&nbsp;in the Vector test scripts for Asteroids based on the CAT Box
  trick to draw a "+" to the screen.&nbsp; To make the Vector test work you must
  disable the WD RESET.</FONT></DIV>
  <DIV><FONT face=Arial size=2></FONT>&nbsp;</DIV>
  <DIV><FONT face=Arial size=2>Any program of length is going to need to service
  the WD RESET or depend on it to be disabled.</FONT></DIV>
  <DIV><FONT face=Arial size=2></FONT>&nbsp;</DIV>
  <DIV><FONT face=Arial size=2>You might want to read up more on the "Quick
  Test" or "Hyper Test" pods as they use a similar method of RAM
  testing.</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>&nbsp;</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>
