Bill of Materials for
"Getting Started"
Parts 1 and 2.

I recommend buying parts from recognized electronics suppliers. If you are lucky enough to still have an electronics parts store in your town (most have been shut down), please consider patronizing them. If not, I recommend any of the following companies:

You can find incredibly cheap parts on EBay. Unfortuantely, counterfeit chips have become a real problem. If you decide to purchase parts on EBay, always purchase from vendors who have a long track record and high consumer satisfaction ratings. Amazon parts also have some issues.

I provide links/part numbers for the places I purchased these parts from. Please do not feel any obligation to order from the same place. I have no business relationship with any of these, other than as a satisfied customer.

In some cases, the number of parts I used are fewer than the minimum order required by the vendors. These are typically for low cost parts costing a few pennies each, so it shouldn't be a problem. You can always use a few extra resistors or LEDs.

The breadboards I recommend are relatively costly as breadboards go. It has been my experience that they are worth it. We may purchase several breadboards as the computer evolves, so you can save money on less expensive ones. In my experience, the cheaper breadboards are not reliable, however.
