Terak page updates

[John Foust]

It's been a decade, and with a recent request for scans from Al, and
hearing of others who've found Teraks, I thought I'd refresh my page.

Notable additions include:

 - Pictures from inside the Terak building circa 1980
 - Terak user group newsletters
 - Terak user group software lists

I think I have a few items up there that Bitsavers doesn't have,
so feel free to grab a copy.
