A friend of mine who likes old computers came over and we played with
the OS9 on my new board. Everything we tried for a couple of hours
worked fine, including assembling an example file using ASM command from
the disk made from the image "microwarea.dsk" made available by Antoine.
The board appears to be a lot more stable than one could fear knowing
about the imperfections of the DMA timing for the Apple 2e explained on
my web page.
Interestingly the command "TMODE TYPE=3" did switch to 80 col mode. I
didn't expect it to work at all as the manual only claims support for
Videx. One little issue with the 80 col mode: the cursor disappeared and
"OS9:" prompt became "O`9:". Probably could be corrected with a software
patch?
I declare the board operational :) Will ship soon as I get CPUs.
