The Windows partition still doesn't work (reboots when I try) but Ubuntu Wily (15.10) is still there. I had to look a little bit around in order to find a mirror that still had Wily files but then "apt update" worked (except for some ubuntu-security stuff) and I launched "apt dist-upgrade". That's going to keep it busy for a while.
The only thing that doesn't work right now (in addition to Windows) is the mouse (still a ps/2 ball mouse). I need to recycle that thing.
- /dev/sda seems to be a single-partition linux disk (mounted at /home) of size 300G, by Seagate
 - /dev/sdb is smaller (160 Gb Hitachi) and partitioned as follows:
 - sdb1 12 Gb= Windows recovery
 - sdb2 80 Gb= Windows (broken), may still contain some data
 - sdb3 4,2 Gb= swap
 - sdb4 38 Gb= Linux (root)
 - CPU is a E2140 @ 1.60 Ghz
 - There are 3 free PCI slots
 - There's an (unused) IDE interface on the motherboard
 - There are USB slots available, looks like 4 USB1 controllers and 1 USB2 controller
 - The Realtek Ethernet controller claims Gigabit ethernet compatibility
 - There is no built-in graphics card, but an AMD/ATI Radeon is on the PCIe slot
