Good news:

I went to see the servers this evening, after a trip to Fry's. I bought a new hard drive (36 Gig U320 SCSI 80-pin) for Pliny's DB and 1 more Gig of RAM for Larousse (that's the best Fry's could do).

Bad news:

Only the RAM got installed. It turns out that the setup in Pliny (unlike every other server in our cage) uses 68-pin SCSI drives. So, my purchase was incorrect.

Summary:

Larousse has 2 Gig of RAM (PC133 SDRAM), 1 Gig more than before.

Pliny is the same old machine.
