I have tested the DOS RAMDISK driver that comes with the PCPI
disk. Works just fine. FID reports about 123K of free memory.
Just 5K for the overhead is not bad. I have the 128K memory
installed.
So the card development is done 100%. I have added an option to
switch the common bank area between 8 and 16K. Since I needed
to change the board a bit I have added an extra touch. A place to
add extension. As an example a tiny USB plug-in board that will
provide an extremely fast connection with a PC/MAC/Linux box.
