I have an old S-100 bus floppy controller board made by Texas
Instruments (TEI). Model FDC-3, uses a Fujitsu MB8876A (clone of
controller. It supports both 5-1/4" and 8" drives.
I'm now writing the disk drivers to be used with CP/M 2.2
The skimpy manual mentions that the board was sold as part of the
TEI computer system (about 1984) and was run under the TEI T/DOS
operating system.
It would save me some work if someone has the source code for the
FDC-3 disk routines, or even the code for the T/DOS CBIOS.
