I got MASM 5.0 to run and assemble properly on the OGO in text mode.
As my first test, I used INT 10 service 0 - change video mode, trying
to get the screen to be fully visible (right now, I can see only
40 of the 80 columns though the cursor does go into the other 40 while
editing, making it a pain to do any editing). I tried every text mode
I could, and none "cut" the screen to 80x25 visible all at once. Does
anyone know a solution to this, if there is one?
Meanwhile, I've been playing with a lot of assembler coding. It's
pretty neat on the OGO, but I haven't tried anything "adventurous"
such as TSR's or inserting one in an interrupt vector chain. I am
not sure if the OGO DOS supports any of those functions.
