I'd use a HTML link to www.digital.com except that redirects to www.compaq.com which then redirects to thenew.hp.com; that, in my opinion, is just wrong. So I use the DEC Alumni organization which fulfills the spirit of the link.
I joined Digital a little after I turned twenty and spent nearly fifteen years. It shouldn't be a surpise to anyone that during my employment at Digital that I held several positions doing different things. However there were three distinct stages.
