Here is the promised walk-through—
The files in VOL1.DSK and their functions follow:
CFMGR <--E/A5 CF Manager program (1st memory image file)
CFMGR/O <--E/A3 CF Manager program (object file)
CATALOG <--TIB/XB program to catalog a disk
CFMGS <--2nd memory image file for E/A5 program CFMGR
EXAMPLE <--TIB example program
LOAD <--XB autoload file to load SLOAD, which loads CFMGR
SLOAD <--E/A5 load utility(?) loaded by LOAD
VCATALOG <--TIB/XB program to catalog a volume
As you can see, CATALOG, VCATALOG and EXAMPLE should all have loaded successfully in TI Basic (TIB).
LOAD will autoload and start with the Extended Basic (XB) cartridge present. It may also run in TIB, but you would need the Editor/Assembler cartridge (see below) and you would need to load it by hand because it will not autoload with TIB. (I am actually not sure it will run in TIB, but I cannot check until I get home in a few weeks.)
If you have loaded the available startup program pack into the FlashROM99, you should have Editor/Assembler II (E/AII), which is functionally the same as the E/A cartridge but written in TMS9900 Assembly Language by Fred Kaal instead of the GPL of the E/A cartridge, the binary for which will not run in the FlashROM99. You should be able to find E/AII in the FlashROM99 menu. Once selected, you can choose Option 5 (“RUN PROGRAM FILE”) to start CFMGR by supplying “DSK1.CFMGR” (without the quotes) at the “FILE NAME?” prompt.
CFMGR/O is the same program as CFMGR but is an object file rather than a memory image. If you really want to go to the trouble of loading and running it, you can choose Option 3 (“LOAD AND RUN”) to load CFMGR/O by supplying “DSK1.CFMGR/O” (without the quotes) at the “FILE NAME?” prompt, <Enter> (with no name) at the next “FILE NAME?” prompt and “SLOAD” (no quotes) at the “PROGRAM NAME?” prompt.
