- No, you are not correct on this. The Super Denise just enables the use
- of several other screenmodes, it does nothing for the flicker in Laced
- modes. The only way to solve the flicker problem is with a flicker
- fixer. For 2000s, that involves either the C= A2320 or Microway
- flicker fixers. For 500s, I believe the Microway flicker fixer can be

- the Denise chip and the motherboard. You'd probably have to cut a hole
- in the case for the monitor connection (but I'm not sure on that part)
- and the fit may be a bit on the tight side if you have any other
- expansions inside the case, but I do seem to remember several
- acquaintances having installed one.
