Re: [M100] Tandy Portable Disk Drive 2 service manual PDF now available.

Seek/Tell is a community extension to the TPDD file-access-mode protocol

            // Seek (Ken Pettit's proposal) for random access
            // file must have been opened in mode 2 or 4
            // ZZ, $09, $05, (type: Begin = 1, Current = 2, End = 3),
Little Endian 32-bit offset, checksum

The idea being random access disk images for use with CP/M

LaddieAlpha implements it. NADSBox since it was Ken's proposal.

Doesn't exist on TPDD 1 / 2.
