There was a multitude of plans for homemade computer desks for the various computer systems back in the day. Over the decades things have gotten smaller, some things on average are no longer used while other new specialty items might require a 'special location' in a modern design.
If you were going to design a custom TI-99/4A computer center, what would you include in the design? Would you add a cork bulletin board type backing, LED strip lighting, built in power strip, a place to put manuals or speakers? How big or small would you make it, what kind of materials would you use? Would it be to house a full blown PEB system or a 'lean and clean' design to support TIPI.
I bet if enough people come in with ideas, we could end up with a couple of totally awesome designs than many of us could benefit from. Please, feel free to come in, toss around ideas, designs or even pictures. Let's see what we can end up with!
