Would that be fairly similar to the one I put at
http://www.imladris.demon.co.uk/pcsp/

last week?

Mine's based on PCSP-1.3, though - there were a few bugs fixed, and Michael
updated it to 2.1.circa88. His 1.3 is on ftp.dgroup.de I think.

If you're interested in making it acceptable to Linus, it needs to be modified
not to share interrupts with the timer. Probably by shifting the system timer
onto the RTC, and using irq0 for the PCSP alone. (RTC can only do up to 8KHz,
so can't be used for the PCSP)

I'd like to have a look at it, but I'm fairly snowed under ATM.
