Here's another really uncommon item, the manual for the TI BASIC Support Module, which appears to be the genesis of the BASIC Support Routines in both the MiniMemory and the E/A cartridges. The cartridge also had a RM option, so it had a bit more of the Minimem in it. . .
I took the scan I had and cleaned it up by typing the entire thing in (the original was too poor in quality to do an OCR scan of it). It includes the source code for the BSM, a debug version of the EA, the EA BASIC Support Routines, and the EA Save routine.
The file is much better size-wise too--535K instead of 6.1M
I have one of the cartridges as well. This manual just completes the set.
