I had the instructions from an old post on FIDOnet, and was also given a sheet from Commodore with the chip (in fact, that's ALL I got; it was wrapped in thin foil and NO other packaging! I finally managed to get some used bubble wrap out of the salesman, but it's really amazing why they don't even have boxes). Anyway, I'm sure the actual instructions have been/will be posted to the net so I won't duplicate it, but I can give some per sonal experience notes: One, the jumpers are a LOT more durable than one would expect; I had a sharp X-acto knife and had to spend several seconds really sawing before I cut through. Second, a tip: be sure not to have any static charges on you while working inside the machine. A good way to assure this is to spray some anti-static monitor spray on your fingers first. Also, I didn't at the time have a soldering iron and so I just taped a little big of foil over the jumper; it worked fine! For about 8 hours... then the pretty green "hardware failure" GURU. After that, I got a friend to solder it for me, and have had no troubles since. Note that you must use Setpatch r if you want the RAD: device to reboot, and this in turn causes problems with VirusX 4.0 until you use the r option of it as well. Note that the old chip is VERY difficult to remove, and the new one is almost as hard to insert afterwards as well. If you can, get a tool for it. I damaged my old chip on removal; you really have to use a lot of force. . <<<>>>
