Solar Program, SID Equipment
Note: Some of the following articles written by Cap Hossfield include references to Radio Shack part numbers. These were commonly available at the time of his writing but may no longer be so today. Cap also includes offers to sell some of the circuits he describes to interested parties and to supply tuning services to those that do not have the proper equipment to do so. Sadly Cap is no longer with us and therefore these offers are no longer valid.
