No, he wrote it for the MITS Altair he bought. Roger said so, in a panel
at VCF-East some years ago. You may be confusing "TDL" with "TEI".
For TEI docs, I only have docs for the mainframe.

Your Web page is a good examination. It notes even board-trace
similarities. It's likely TEI copied the IMSAI and then added their own
features. Lots of copying went on in the S-100 era, down to replicating
boards completely. If it's that similar, then producing a schematic may
be a matter of verifying the board with ohmmeter following (and
correcting) the MPU-A schematic.
