tipps for hardware issues:
Remember to use only 80-wire ata cables (not only for hd but also for cdrom).
Best if buying Ram at your Pegasos dealer (he knows the best types)
Read the specs of the interanl connector carefully. Cabling the internal usb connector:
At the mobo there are four panels near the memory slots present. Two of
them (the both neigbouring to th ecpu slot) are for IDE, then there
are two more left one for the floppy (well noone needs this..) and one
26 pin connector (just neighbouring the memory slot) for multiple
purpose. If you look at that connector there are two rows of pins. If
you look to the mobo that the front panel of the Peg (i.e. the
external ports like parallel, usb, ps/2) are on your left hand you
have to count the pins of that connector from the top on. The
right pin row starts from the top with one not used pin and then
4 pins for usb connectivity starting with (counting from top
downwards!!)
- gnd
- usb signal D+
- usb signal D-
- usb 5 volts
your case should offer four cables per usb connector on the front.
These cables should be taged somehow like usb1 gnd, usb1 D+, usb1 D-,
usb1 5V and the same set with usb2 gnd, usb2 D-, ... Choose the 4
cables according to one connector and plug them into the connector.
Take care that you dont mess up one of the cables, your Peg would not
thank you that!
Again all pins on the right row of the connector
1 - not used
2 - usb gnd
3 - usb D+
4 - usb D-
5 - usb 5V
6 - KCLK
7 - KDATA
8 - -SCLK
9 - SDATA
10 - HDD LED +
11 - Power LED +
12 - Reset (pin A)
13 - Power on (pin A)
The left row is
1 - PC speaker Pin A
2 - not used
3 - not used
4 - PC speaker Pin B
5 - IRDA power supply
6 - IRDa RX2
7 - IRDA RX
8 - IRDA GND
9 - IRDA TX
10 - HDD LED -
11 - Power LED -
12 - Reset pin B
13 - power on pin B
Do not hesitate to ask for further details...

Whenever you're sad just remember the world is 4.543 billion years old and you somehow managed to exist at the same time as David Bowie.
