Firstly I do realize that there are newer/better UARTs available than the 8250
but a 8250 is all I have available right now to experiment with. :-)
I need an URL to locate a schematic on how to hookup a 8250, 1488 and 1489.
I've spent the last couple of days searching the net but can't seem to turn up
anything except for one schematic that shows the UART but not the 1488 and 1489
BTW, this schematic shows the timing crystal directly connected (via R/C
components) to the 8250. Is this correct? Is there no oscillator (eg 555
timing) or binary counter IC (eg 74HC6040) needed for this UART?
Any information would be much appreciated..........thanks! :-)
