I had exactly the same problem trying to boot 9sscpu on a
SparcStation 2.

read()/write() to #c/key etc. requires the global variable cpuserver
set to 1. mk 'CONF=sscpu' generates /sys/src/9//ss/sscpu.c, which
has the line
	int cpuserver = 1;
near the end. This is shadowed (somehow) by /sys/src/9/ss/main.c:15
	int	cpuserver;
here, cpuserver is implicitly initialized to 0.

My fix:
term% diff /n/cd/sys/src/9/ss/main.c /sys/src/9/ss/main.c
15d14
< int cpuserver;

I guess the same fix has to be applied to /sys/src/9/ss10/main.c,
but I don't have a machine to verify it.
