I have manuals for the Tecmar PC-Mate Floppy 5/8 and also the SASI 
adapter that was part of the PC-Mate system.  Not sure if this is the 
same Tecmar floppy adapter it is a full length 8 bit ISA card with a 50 
pin connector at the rear of the card and two 34 pin edge connectors at 
the top near the back for 5.25 drives. The floppy controller chip on it 
is a UPD 765.

There is also a manual for the Xebec S1410 SASI to ST-406 controller.
