[snip] Not that the machines of the time really ever kept up with the mouse anyway! I've got a Mac 512Ke. It keeps up with mouse movement no worries. The very early Macs had the mouse trip a CPU interrupt directly in case you're wondering how they managed it. I know exactly how the macs did it, pretty well the same way everything did, but i was refering to the suns workstations. If you meant Suns only, why refer to `machines' in the general sense as you did? A mistake. Although as pointed out - the mac cursor fell apart when reading the disk anyway. Not really, no. It could get a little jerky sometimes, but it was still perfectly usable. It got jerky to the point that you couldn't use it to any reasonable level. At least all the macs with floppies I used did, maybe yours was better. It was worse on the original (1984) 400k floppies, not so bad on the 800k drives (1985 onwards), and not really noticeable on the 1.44 MB Superdrives (1987 ?). I don't recall the mouse ever being unusable with any of them, although I seem to remember that formatting a floppy was the worst for mouse jerkiness. It was pretty unusable when formatting, but as you said, it got better.

Wasn't there something different about the way the original Mac controlled the floppy drive using a spare pin or something? It might have been different enough to steal interrupts from the mouse. Or am I thinking of the sound hardware? Cheers, Chris

The original Mac used variable speed drives, as I recall. Was that it? It also packed in more information by using variable bit density.

I can't think of a 'better' solution though, so I can only sit on the sidelines and criticise. You know how Omniweb and SafariStand display tabs as mini-pages? Might that be a better solution? Click the minimise button and the window becomes a tab, easily recognisable and easily accessed.
