Yves,
I'm not an experienced programmer, but I do own the IIgs Firmware
manual. I'll try to see if there is something there about accessing the
slots. Through, I don't doubt that there are people who read this list
who can answer your question off the top of their heads.

Hello Apple 2 fans,
I'm an experienced Apple ][+, //e programmer but a newbie when it comes
to Apple 2GS 16-bit mode. I whish to experiment with a sprite card
based on TI's TMS9918A chip. I'd like to use Orca PASCAL for this
instead of fiddling with PEEKs and POKES and their negative decimal
addresses and data or using assembler which is tedious to use for a
first try. I'll use assembler later on to write a more efficient device
driver. Anyway, here's my question: is there a PASCAL programming trick
to access memory space dedicated to slot 1-7? On the same line of
thought, are there online reference on GS hardware architecture? I
have the Toolbox reference books vol. 1 and 2 but I miss the rest of
official Apple 2gs book collection.
Thanks,
Yves
