I/O Error generally means the drive is not being seen on the serial port. Does the serial port on the machine work? Can you check it out make sure it is working? Link to a PC and use TELECOM to a terminal program or try the new mcomm out.
Could be a bad TPDD cable I had problems with mine it was not making good contact into the drive, I had to have it just in the right position to work. I stopped using it after that :) ________________________________ From: M100 <m100-boun...@lists.bitchin100.com> on behalf of Chris Kmiec <ckmi...@gmail.com> Sent: Saturday, March 24, 2018 23:46 To: m...@bitchin100.com Subject: Re: [M100] Tandy Portable Disk Drive... Well, I have REX, with TS-DOS, and also tried the installation/bootup procedure from the manual. Didn't work either way - I/O Error. I looked over the board, and don't see anything obvious. Everything cleaned, etc. My "big score" with a DVI, TPDD, and M100 has had an issue with every single component... At least it came with a ton of cables, manuals, and disks! Unless somebody can suggest anything else I can try, I'm giving up on the TPDD for now, too many things I'm working on, including getting the drive in the DVI to work.

There is at least one or two programs just for loading and unloading the dvi dos and a tpdd dos so you can switch between them without actually wiping and reinstalling each time. There is (on p. 7 of the TPDD2 Manual) a cryptic related reference that the utility disk can’t be used with a computer in conjunction with the DVI, so maybe these can’t all be used at once, -- bkw
