gdm2k
The Geneve DiskManager 2000 is a very handy file manager program. It makes it a lot easier to copy, move and rename entire directory hierarchies, which is most useful to me.
There’s also a video on YouTube which shows the program in action.
Archiver III
The myriad of “ARK” files you might find in the TI99 space are actually compressed archives made with a program called Archiver III, by Barry Boone.
Note: this is one of those programs that needs to be EXEC’d (you need to run
EXEC ARC303G instead of ARC303G directly)
qde
Clint Pulley’s qde is probably the most straightforward and useful text
editor for the platform. In my opinion, it offers a good balance between
simplicity and usability when it comes to manipulating plain text.
qde is better than MY-WORD for plain text because MY-WORD is really for
honest-to-goodness word processing. MY-WORD documents are not plain text;
they have all manner of binary formatting commands interspersed throughout
them.
qde is also better than the traditional Editor/Assembler (EDIT) because
it is really optimized for writing code in assembly language. The default
tab situation alone makes it annoying to use for drafting natural language
text.
QDE is available in the Full Geneve Package
inside the MDOS dir inside the the MAIN.CHD hard disk image, but you
can also download the standalone floppy image. The floppy image
represents a 360k disk – if you’re using MAME, that means you should tell
MAME it’s a 525dd type instead of 35dd, something like:
-peb:slot8 hfdc -peb:slot8:hfdc:f1 525dd -flop1 disks/qde33.dsk
