Hi all, recently i just restored a 2008-66M T60 and i'm planning it to use for some flash games, basic programming and maybe watching youtube.
I was thinking if the Broadcom Crystal HD is a worthwhile purchase for the T60? especially nowadays? most posts I find are during 2011-2015ish or am I better off
just buying T7200 without the broadcom chip?

Many thanks in advance!

My friend has a Broadcom Crystal HD on his X61. From what I remember, it doesn't work on Windows 10.

In case you plan to use the crystalhd card in a recent Linux, here are up to date sources for the required kernel module:

github.com/dbason/crystalhd

I was just able to successfully compile and install the module with the current 5.10.0-7-amd64 kernel in Debian/unstable.

Also, remember that on T/R/X60 and Z61 series, you have to use the Broadcom Crystal HD in the WLAN slot (and use a USB WLAN in the WWAN slot or an external WLAN). That is because the WWAN slot lacks PCIe lanes.

Nice find! I remember this module got removed from the mainline kernel due to a lack of people wanting to maintain it.
I wonder if Broadcom would consider making a new version of this chip, but with H.265 / HEVC support. :D
