I actually had one of these, http://www.ebay.com/sch/i.html?_sacat=0&_from=R40&_nkw=alpha... but the first edition that ran off of AA which looks a little rare (good thing because the keyboard started to stick, oh and dump the contents as everything is stored in RAM).
That, in my mind, would be a programmer's computer. (Or a writer's computer.)
