 Another datapoint: If I remove zstty1 from the RAMDISK kernel config 
 for sun3, then the RAMDISK kernel gets past this hang point...
 
 I note that in obio.sun3 we have:
 zsc0    at obio0 addr 0x000000
 zsc1    at obio0 addr 0x020000
 
 but the default config for tme says:
 zs0 at obio0 addr 0x020000 ipl 6: tme/machine/sun3/zs
 zs1 at obio0 addr 0x000000 ipl 6: tme/machine/sun3/zs
 
 which would swap around zstty0 and zstty1 ??
 
 Later...
