I would like to hear from anyone with first (or second) hand information
regarding 68020 boards for the 1000. There seem to be 3 boards available:
Sapphire (Gemstone Group), Hurricane (Finally Tech.), and the CSA
chassis/board (which I probably can't afford). Anyone know anything about
the Sapphire or Hurricane boards?
Thanks.

Except that it's a real SOB to install. Mine is still the 7 mhz version but I plan on upgrading it to 14 megs RSN. I got it to do a 68881 version of Galileo. -- *** mike (Cyberpunk in training) smithwick *** "live long and multi-task" [discalimer : nope, I don't work for NASA, I take full blame for my ideas]

The most notable of these is that the system seemed to behave somewhat flakey after I installed the '020 card. Software that used to function flawlessly (like VD0) started failing sporadically. It turns out that you *must* have the PALs in your 1000 firmly grounded in order to get anything approaching reliable operation. Also, the PALs on the '020 card itself are a bit noisy, and grounding them won't hurt. Once things are grounded, then the things runs like a champ. Also, the first pass on the PALs on the Hurricane card had some minor errors in their equations, so be sure you get the latest revision of the PALs if you decide to order one. Other than that, it is a welcome addition to my Amiga, and the speed-up in some operations is downright *scary*. N.B: If you're marginal with a soldering iron, like I am, don't try to ground your system by yourself; you might screw it up (like I did). Invest in peace of mind, and pay someone you trust to do it. Few things feel worse than the realization that you have just accidentally murdered your Amy... _-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_ Leo L.
