From 3ba2f6e5c7383c5d7a6f8a1c38b6b5403a8a5dcb Mon Sep 17 00:00:00 2001 From: Solomon Peachy Date: Fri, 23 Apr 2021 11:09:49 -0400 Subject: Nuke all TCC77x targets: iAudio 7, Sansa C100, M200(v1-3), Logik DAX They were never finished, never saw any release ever, and haven't compiled for the better part of a decade. Given their HW capabilities [1], they are not worth trying to fix.
