An original Compaq "portable"

Nadeau's book gives a range of $20 - $75, but I wouldn't give $20 for the hardware alone. Original documentation and software, on the other hand, is likely much harder to find and would be worth some extra $$$s. It's hard to quantify value if you have all the extras, which are often almost impossible to accumulate. I think most collectors know that documentation is far more difficult to find than machines. I have an IBM 5100, which is somewhat rare, but what is really rare is the full set of documentation I have, including the original sales invoice and factory build sheet. For example, I have a Texas Instruments Portable Professional Computer (actually I have three of them) which in terms of hardware, is not worth much ($15 to $40 according to Nadeau). But, I also have virtually every piece of software and documentation that ever went with it (all in those hideous orange TI boxes), as well as a big box full of development boards of every variety that I got from a retired TI guy that worked on the project in the early 80s. I also have stacks of preliminary production documentation and schematics from the same sorce. Now that's history -- and as they say in the Master Card commercials -- "priceless." By the way, one of my three TIPPCs has an upgraded 286-10 Soyo MB and is IBM compatible (and therefore won't run the bulk of the specialize TI software). Anyone ever see one of these before? -W
