As you will see in the manual the 880 can use either the OPC-478 or OPC-1529R cables. If you search the internet you can easily find the pinout for these serial cables and make your own if cost is a real issue. The cable is a very simple 3-wire hookup. Either cable will work with many USB to SERIAL adaptors. Some people have problems with the adaptors, but they are pretty cheap & I have used several without problem. You can buy a copy of the 478 cable on Ebay for about $7 delivered - pretty cheap. They work fine. The USB version runs around $12 delivered - but I have not tried these cables. The OPC-1529R is much more expensive - for reasons I can't understand. Demand maybe. However, it is the one you need if you want to to send data thru the radio. Anyway, I would get the 478 to start, and plan to build the 1579 yourself later - total parts cost is about $5.. 73 Ted W1GRI
