When upgrading a TRS-80 to double-sided (or just commercial standard) disk drives, you need not buy a new cable. Just buy the 34-pin female edge sockets off the wall at the local Shack ($4.95 each) and use a vise to clamp on to your existing RS cable. Put the new connectors next to, or halfway between, the old ones or wherever works out for you physically. The controller end of the cable has all the wires connected, so this works. Use the old sockets (keep using them) for your RS drives. Using the side-select lead for the 4th drive is still done on the Color Computer. When you upgrade to double-sided software, you can use only 3 drives. PS: Be glad you have Radio Shack. Most other home computers use screwy disk interfaces, so Atari, Commo, and Apple users can't go out & buy those neat Tandons, TEACs, etc the way we can! Thank God for standards, an Tandy for sticking to them.... mike k
