Sorry guys, but I'm jumping up on the soap box for this one. I'm quite stunned by this email. First, there is the official protocol put out by Tandy "Software Manual For Portable Disk Drive" 26-3808 http://manx-docs.org/mirror/harte/Radio%20Shack/TRS-80%20Model%20100%20Portable%20Disk.pdfThere is a full writeup on bitchin100.com http://bitchin100.com/wiki/index.php?title=TPDD_Base_ProtocolAnd if that's not enough there is the TPDD2 sector access protocol writeup www.club100.org/memfiles/index.php?action=downloadfile&filename=TPDD2- Sector%20Access.txt&directory=Kurt%20McCullum/TPDD%20Client& To suggest that somehow those of us who have created TPDD emulators are somehow hiding that information is silly. Ken and John have done a huge amount of work and documentation and that has been for the 'benefit' of the Model-T community. LaddieAlpha/mComm/Desklink and more are freely available for the 'benefit' of the Model-T community. If others want to create a low cost TPDD emulator, I'm all for it. We are not hiding any secrets here. Stepping down from the soap box now. Kurt
