Re: Apple lle display

Show all headers | View raw

Thanks for the info Michael.  That does make some sense.  However the rnd 
"mode" you describe doesn't seem to fit.  When I randomize the string from 0 
to 1 and then multiply it to get the integer value on MS BASIC, the line 
command works fine.  However, I found that when I input the same line in the 
Apple, the command fails.  When I change the rnd value to a -1, and follow 
with the same multiplication for the integer value, the Apple accepts the 
line and the program continues with the exact same results.  I know it's no 
real big difference, but there are numerous little differences between MS 
BASIC and Apple BASIC.  It's these little differences I actually like about 
working on the two systems.

As for what's wrong with the monitor, at this point, I think it's something 
in the main power supply.  The fuse I replaced is in the power supply 
circuit.  As soon as the power switch is turned on, the fuse blows.  I don't 
really know much about electronics.  As far as equipment, I have a volt ohm 
meter to check circuits with.  It's good for tracing an electrical path of 
the lack thereof.  That is pretty much the extent of my electronics repair 
knowledge.

As far as the monitor goes,  I wouldn't mind upgrading to a color display. 
I know that Apple lle has built in support for color, but Apple decided to 
offer a monochrome display.  Probably to save on cost.  I haven't used the 
computer much simply because of the monitor issue.  I guess I could put the 
Apple on a rolling desk and connect it to the TV in my living room, but 
being wheelchair bound and only having one arm to do anything with makes 
even that a chore.  Still, I really want to use the computer.

Any way, thanks again.  I'll keep looking around and wait for my friend to 
come to Vegas so maybe he can see what's really going on with the display.

The +1 argument is only a "mode" argument, telling RND to deliver
the next pseudorandom number in the sequence.  Any positive number
has the same effect.  The number returned is always in the range
of 0 to 0.999999999 and this range is not changeable.

A zero argument returns the previous RND return, while a negative
argument re-seeds RND to start the sequence from a new point.

Just out of curiosity, what appears to be wrong with the Apple monitor?

Great!
