Last updated on 3rd February April 2012 Compulink does not sell any computer hardware, however, we can offer the below guidelines as to what you will need. Because each store is different, you might consult with a local computer dealer to determine your particular needs. You can get computers mail order or from a local shop that builds them. The Jewelry Shopkeeper software will work on almost any PC running Windows 7, XP or Vista but if you do not have a computer, or you plan on buying a new one, we would recommend a more up-to-date computer such as ne with the following specifications: The "processor" should be a Core i3 to i7 or AMD equivalent; The hard drive should be  500GB or larger, and the RAM should be 4GB or more. You can use either a flat (LCD) monitor are usual now.  If possible see if the computer can include a parallel printer port. Most of your backups will be done with USB Flash drive or onto CD's and DVD's so a special backup system is not usualy required. Windows 7, XP Professional or Windows Vista are compatible (32-bit preferred over 64-bit versions). If you select a low $300 to $400 priced computer it will usually come with Windows Home - but you can usually pay the extra $90 and request the Windows Professional upgrade. Expect a price range of $300 to $800 for a computer without a monitor. For best customer support from Compulink, we highly recommend you have an internet e-mail account, a LogMeIn account and a fax machine. A UPS (Uninterruptible Power Supply) is recommended for each computer. This is a battery and surge protector in one which keeps your computer running in power outages or disturbances. A small $100 one is usually sufficient to keep your computer up for 10 minutes or so but check with the seller on UPS capacity requirements. Note that UPS’s are unreliable after 2 - 3 years. If you plan on point-of-sale use you probably need a network of computers (one or more for sales registers, one or more for bookkeeping or inventory processing.) Note that registers require actual computers, not just screens. If your Shopkeeper is a single-computer version you may want to consider a network version to allow simultaneous access to Shopkeeper from more than one computer. For point-of-sale, you will want reasonably fast computers to speed the customer's transactions. (sometimes people think to put slow computers thinking "It's only a register") This doesn't mean you need to buy a particularly fast computer but it does mean you might not want to use your 6-year old computer as the register.   The network features built in to Windows 7, XP Pro or Vista are sufficient for a small network of 2 to 8 stations. Don't get a special Server version of Windows  unless you have a large network or special applications that require a  Server version. Where possible avoid wireless networks - use cabled gigabit ethernet cables and equipment to connect computers. Where you really need wireless, use the faster “N” type. For price-tags you use specialty barcode tag printers such as a Citizen CLS-631 or Datamax E4205A O’Neil Mark III.  Note that barcode tag printers print tags ONLY (nothing else). Standard laser and inkjet printers do NOT print price tags.) Hardware & Equipment Click Here for Examples of Hardware: Brands, Model Numbers and Suppliers
