Must have books for Vintage Computing

I'm building my personal library for vintage computing. I need to probe the collective wisdom of the list in what books must a "wannabe" collector (like me) should have on his/her bookshelf. Although I collect primarily DEC stuff, I don't want my knowledge to be just restricted to what DEC had to offer. p.s. Don Lancaster's books are the first on my list. :-) /wai-sun Lancaster's TTL Cookbook is a great place to start. The most indispensible book in my collection is _Bowker's 1985 Complete Sourcebook of Personal Computing_. This 1050-page (2.25" thick) buyer's guide is just loaded with information about the state of personal computing for that year. (I used to have the 1984 edition too, but I gave it away long ago). If you can get your hands on any of thier sourcebooks you will be very happy with it. A couple of other suggestions also come to mind. If you're at all interested in CP/M, then you should have The Waite Group's _CP/M Bible_ and it's companion book _The Soul of CP/M_. --T Jam the computer...trash every lethal machine in the land! --Timothy Leary
