Can't beat Alice's shopping list, but I would add Peter Anderson's Logic Probe/Pulse Generator for $5. You can get many of your parts from him also. http://www.phanderson.com/ordering.html Good luck and have fun, - Nick - Alice Campbell wrote: > > Subject: Re: Questions from a beginner... > Date sent: Fri, 10 Dec 1999 09:38:39 -8, PST > > Challenge: can anyone do this cheaper than me? > > Shopping list for absolute minimal beginner entry--many > substitutions are of course possible: > > Computer: old computer running DOS-- even old 8086 compaq > portable running off 2 floppies with no hard drive will actually work. > About 10 floppies.
