Re: Is it possilble to use timer interrupt in Apple II?

[bluebird <mildstorm@gmail.com>]

Dear Albert,

I tried to make Super Serial Card communication with PC.
At first, I implemented it with status machine method which checks SSC
status and tx/rx the data.
The method I applied is the same with what you talked to me.
=> There is no execution blocking while sending/receiving.

But I thought it will be more simple with interrupt handling.
I don't know whether SSC generates interrupt in relation with RX/TX.
=> Currently, I am going to try it with BRK interrupt.
     (Actually, I am novice in Apple II S/W, H/W)

------------------------------------------------------
I wanted to know whether setting timer interrupt is possible not.
If setting timer interrupt is not possible, making RTOS(which is
preemptive as you know) is impossible.

Thanks for your kind explanation again.
