I have some firmware chips in a 21MX/E that I can't seem to identify from my docs, and some I think I know what they are but not sure. 13307-80036, 13307-80037, 13307-80038 I think these are DMI 5090-0589, 5090-0590, 5090-0591 I think these are FPP 92067-80001, 92067-80002, 92067-80003 I think these are EMA (used by RTE?) 93585-80006, 93585-80007, 93585-80008 No clue, may be proprietary ProVOX? 92084-80004, 92084-80005, 92084-80006 No clue, may be proprietary ProVOX? 92084-80007, 92084-80008, 92084-80009 No clue, may be proprietary ProVOX? Can anyone help and confirm or deny any of this? Jay West
