Hi,
As you might know, I am writing some programs for joynet. While I was
testing something I found out about some problems which are quite
important to other people who want to make programs for it.
The MSX BIOS (at least that of the philips NMS8250 and NMS8245) changes
the values of the joystick connections. Probably it will nopt change if
the strobes are 0 and the A and B outputs are 1, but I am not sure about
this. It is quite important if there is a situation where you can have the
interrupts switched on, so it will be possible to have disk-access. So
please, if anybody knows what the BIOS does with the ports, and if there
are any guaratees about what it doesn't do?
Bye,
shevek
PS: I have some software ready for using the joynet with an asynchronous
protocol. I will put it on my homepage soon. It is freeware.
