Hi again
It's hard to say which of this two systems is "more valid"... you'll find people who like FSBUS, and others who prefer IOCARDS....
In general, you can say, that
--> if you really like electronical stuff and if you are able to produce PCBs by yourself, AND you don't want to pay that much... choose FSBUS
--> if you don't like (or if you are not able to) produce your own PCBs or if you've, like, 'never soldered before' or something, AND you have some money left... IOCARDS may be the right thing to you.
Of course, this is not really true at all: you can also buy already assembled FSBUS-components (e.g.
http://www.cockpitsonic.de/) or you can make IOCARDS on your own....
So, it's your decision
best regards,
Chris
