Didn't find firmware upgrade remaining available from Apple.
Firmware upgrade not necessary.

Replaced one of the 1066 MHz DDR3 SDRAM cards with a 2 GB or GiB card.

# hwinfo --memory
01: None 00.0: 10102 Main Memory
  [Created at memory.74]
  Unique ID: rdCR.CxwsZF jVASF
  Hardware Class: memory
  Model: "Main Memory"
  Memory Range: 0x00000000-0xa9c90fff (rw)
  Memory Size: 2 GB + 768 MB
  Config Status: cfg=new, avail=yes, need=no, active=unknown

Set up the HDD with GPT.  Installed including EFI booting.

Added firmware-b43-installer for the WiFi hardware.

No problems evident.  Useful system.

Thanks,                       ... P.
