I'd like to try some unusual set-ups with GS/OS. I've ordered the GS/OS
Tech Ref, and I should have it in 2 weeks. For programming, I have Orca/C
and Orca/M (updated).

A couple of questions regarding GS/OS :

Q1 : What is the minimum configuration for GS/OS (list files) ? Assume
     that I have some application (S16 ?) which takes care of needed tools,
     graphics, I/O, and uses GS/OS MLI calls. For ProDOS8, it would be :
     Files: /PRODOS, /the_program.SYSTEM (Filetype: SYS)

Q2 : What Toolbox dependencies does the GS/OS Kernel have ?

Q3 : How do I make an S16 file ? Is it as simple as changing the filetype
     from EXE to S16 ? Is the GS/OS MLI Quit good enough for a "clean" exit
     from the program ? Is there anything special that my program needs to
     do at startup ? Assume that I'm using direct screen writes in 40 columns
     and reading the keyboard at $E1/C000 to keep things _reeeeeal_ simple.

.. and since there's so much talk ...

Q4 : Did anyone buy/get an Apple IIgs because he needed _MULTI-TASKING_ ?
     Personally, background printing and background X-Modem are all I would
     have much use for.

Hmmm .... Maybe someone could write a CDA that could initiate an X-Modem
transfer with just interrupts. Intercept the ProDOS8 MLI as soon as the
transfer begins, force any call to wait until X-Modem is ready to write its
buffer (or read, ... keep an eye on close commands) Once the transfer starts,
you could leave the CDA and play with Applesloth (or some other stuff). WHY
I THINK I'LL WRITE IT TODAY !!! :> =sorry, I guess I'm teasing= Even though
I have started work on an interrupt based dumb terminal CDA. Serial IRQ
handler ... crude but it works. Sound IRQ handler ... it's Ok. Main CDA
program segment ... looks good for a couple of diagrams and some notes. :>
