f-log

So the Saturn problem I was having was not what I feared, a knackered motherboard. A number forums were reporting that newer TVs could not cope with the badly designed Saturn SCART cables and suggesting convoluted workarounds using SCART switcher boxes, but, in fact it was a bent pin in the video connector.
Slowly applying pressure via a small screw driver restored the pin and it lives once again.
Sadly my favourite Saturn game Burning Rangers never survived the loan of the Saturn, but I can still have some retro gaming with the kids.

ISPY Raspberry Pi

Got 512MB Raspberry Pi model b) for Christmas.

I don't have a HDMI ready TV and it is not practical to try and hook up the RCA connector.
So my Raspberry y Pi is headless, no visual output (except the status LEDs).
The Raspberry Pi is up and running according to the status LEDs so how can I find which IP address it has been assigned ?
NMap to the rescue, it will check each IP address in a specific range and locate open ports, the Raspberry Pi Wheezy distribution has shh on by default.

-n for 'no name resolution' and the /24 is the bit mask to search from 0-255, that only affects the last number(octet).

In those results;
15 is the machine I am using
200 is the router
20 is the Wii
14 and 37 are IPhone/IPad devices (not mine) so that leaves
38 for the PI

-O is OS detection

Note that NMap is using the MAC address of the ethernet port to identify the Raspberry Pi
then its just

ssh pi@192.168.0.38

say yes and enter the default password "raspberry"

Although its unlikely, your DHCP server(the thing giving out the IP addresses) might give the Raspberry Pi a different address next time it is booted, in which case just repeat the above to find the new address.

next time ... PANIC! (in a good way)
