I understand that it's the developer and pre-release machines.
I wonder if the units sold to video game manufacturers have the same
problems?  Hmmm.

Commodore could provide a number I'm sure.  It's easier 
for you to just check your machine.  Program follows.

If you have extra memory on your computer you will have two times.
One normal (in your extra memory) and one with the memory removed,
or a "noFASTmem" type program run.  (noFASTmem is on the A500/A2000
Workbench disk).
If the second time is greater than 10:31:00 you have a bad machine.
The first time depends on your RAM board.  Send the times to
the address below to be added or averaged into the summary. (I don't
need times for the extra memory that plugs into the A500's bottom
compartment)

Be sure that you are displaying the standard 642*200 workbench.  Make sure
that this program loads into the type of memory under test.

When started the power LED will dim.  In 2 seconds the LED will go bright
again; start your stopwatch now!  Go away for 9 1/2 minuites.  After that
observe the LED.  Within 90 seconds or so it will go dim.  Two seconds later it
will go bright as the signal to stop the watch.  The machine is locked up
for the duration.

This program uses direct hardware writes and will break on future Amigas.
Ok for the A1000,A500 and A2000.

Record the time with noFASTmem, without, computer type, and
the manufactuer and model of RAM under test.  Send them to:
