Robert,
First of all, Welcome to the "G". Congrats on your first post!
Wally gave great advice.
We no longer have our Wizard 8000, but upgraded the computer at least 4 times over the years. We used to retire the front counter POS computer to serve as the Wizard computer, every 2 or 3 years, and get a new one for the front counter.
I suggest using a computer with the latest Windows 10, 64 bit version. 8-16gb memory and a 512tb or higher hard drive are good goals. It doesn't have to be an expensive PC.
Wizard upgraded the drivers, so even the older (tan) driver packs will work fine with Windows 8, 8.1, and Windows 10. (I only suggest Windows 10!)
You will need to get a current version of the software from Wizard, as well. Mat Designer was actually retired several years ago, and replaced with a completely re-written product. The FrameShop software initially only ran on the newer Wizard CMCs, but now they are upgrading older CMCs that used Mat Designer. MatDesigner and FrameShop both require activation codes when installed on a new computer (a string of letters and numbers), which are good for one time use. You'll need to contact Wizard for advice, support, activation code, and to make a decision if you want the final MatDesigner release, or the newer product that is improved regularly.
They will advise, but one thing that always worked well for me in the past was to copy the Wizard program folder over FIRST. This way it preserved all of the previously saved job files and imported the board calibrations from the old computer to the new. If you otherwise start with a clean copy, you'll have to "dial it back in" with a bunch of adjustments for each type of cut. Every cmc is unique in how it is calibrated for perfect cuts.
Another tip, if you bought it outright and aren't on a corner/leasing program, is to keep the old computer as a "backup". In the event of a system failure, we always had the option to plug the old computer in to be back online in a few minutes. (with older software) It gave peace of mind to have a backup plan.
Best of luck!
