@Groepaz: I doubt that, since it probably wouldn't pass his "install by girlfriend test" which prevented an internal ACA500 for example. And this most likely wouldn't be any easier to install for said girlfriend...

Ugh, phrasing. My wife's at least as capable as I am at installing hardware.

We've both dismembered various tightly packed laptops and small formfactor PCs to replace drives etc, and her soldering's a hell of a lot cleaner than mine is.

@ChristopherJam: you said wife, AmiDog was talking about girlfriend. Probably you wounldn't have married her if she did not pass the girlfriend test.

AmiDog: a much more important reason is that it will not work the same on different board revisions, and require soldering with some of them. ie: support nightmare.

"Is there anywhere a list of releases using VSP?"
ugh, no. that'd be a huge list =) however, the problem even exists for programs that dont actually use VSP, but simply switch $d011 without synchronizing to the beam - which may or may not trigger the bug (with a roughly 1:312 chance)


I never took a while to think about it but you are obviously right. Anyway I still wonder how many releases are being hit by VSP issue. In case of demos I doubt there is a lot of software not synchronizing with beam.

you can almost bet on that a random program that uses raster irq does a non synced write to $d011 somewhere at the beginning :)
