I go back to the Sinclar 8k. I have been fixing and building systems for friends and family members. The hardware part is still easy but when it comes to software problems I find myself being befuddled over things I know I have fixed in the past. I still am able to find and fix most problem after taking many unnecessary steps. While you are still in control of all your marbals make a simple leger of problems you enconter and the steps that fix it. It will save you from pulling all you hair out at a later date.
