If General Computer hadn't bought every low-profile test clip available, Levco would have used them too. The Levco chip-clip is a kludge of the first magnitude: the connectors that "bite" into the 68000's pins weren't made to do that -- they are wire-wrap pins and their sharp ends were never meant to be used as either permanent contacts or mechanical supports. No wonder they give out after one or two assemblies. Which is too bad, since in all other respects the Levco accelerator is/was an awesome product. -Zigurd
