Here is a list of vendors who are more or less active in selling Sinclair equipment, software or services. The list is presented as a service to the reader. It is difficult to keep up with the activities of vendors because their interests (and stock) are continually changing; however I have seen some indication of recent activity on the part of all the vendors listed this month. In some cases I have added a line after the address giving my impression of the principle equipment or service that the vendor offers.
If any reader knows of any other names that should be added to this list, please let me know. Also it might be helpful if, when you write any of them, that you mention that you saw their address in QZX and that it would be useful if they took out at least an unclassified ad to help people keep up with their offerings.
