Close, but no cigar. Every line of the rainbow should be solid with no
flicker.

I finally broke down and ran this on my IIe, and all I can say is:

ROY G. BIV !!!

Well, actually, more like ROY G. BI or maybe ROY G. BV, but it was
cool to see in HGR mode!

So,

I've refactorized the timing component in OpenEmulator, and thinks
seem to be much nicer now :-).

http://openemulator.googlecode.com/files/rainbow.png

There is still a problem with two bars that flicker at the beginning
(I posted the worst case)... does that happen on an Apple II as well?

With the best wishes,

Marc.-

That is almost correct, but not quite.

Every bar of the rainbow should be of uniform length. There should not be
any flickering at all.

Hello D Finnigan:

thanks a lot for your help! By "uniform length", do you mean that the
LORES lines do not have the same length as the HIRES lines, or
something else? Would it be a lot of trouble to post a picture of the
output on a real Apple II?

I emphasize this, because I feel this is an excellent test of the
timing emulation. It not only tests horizontal but also vertical
timing.

I must also confess that I still have to go into the code further to
fully understand what is going on :-).

With the best wishes,

Marc.-

In the screenshot that you posted, not all of the lines of the rainbow were
the same length.

On a real Apple II Plus, all lines should be the same length.

I will take a picture and have it online tomorrow.

Some 16-leggedy creatures congregated in my Apple II Plus, and this is what
they made:

Virtual ][ v6.5 for OS X was just released and it supports this
floating bus test now-no more flickering of the red and yellow lines.

I also tried this program on a ROM 255 Apple IIc and an unenhanced Apple
IIe.

Results:

The screen from the Apple IIc matches that from the II Plus (save for the
color tint).

However!

The Apple IIe showed a funny little "glitch" right at the right end of the
blue bar. The blue bar appeared to be slightly longer than the other bars,
and just the right end of it appeared to be flickering very slightly.

That's an interesting usage of "cleaned up".

Well, I was too lazy to bust out ADTPro, so entering this manually on the //c forced me to "compact" it.

Yeah, your probably right, should of said "compressed/optimized for manual entry." :-)
