YDL install on pismo fails

[Rich Simpson]

I posted before about a failed install on a G3 firewire laptop 500mhz 
(pismo), It has the original dvd-rom module in the media-bay, 256MB ram 
(apple installed) and 12GB HD. I have tried a text install as well as 
the gui install, and it does the same thing, it starts installing and 
then just stops, no errors it just sits there for ever. I used the same 
disks to install on an emac and it worked fine, so I assume my disks 
are good. Any ideas about what is wrong here?
