I've been slowly making new models of my VCS portables since 2000. Granted, most of them appeared in 2001, specifically revisions 2-5, but every so often something new comes along. For this strange and unique Atari portable I decided to slap a 7 on it. Why not?
I had a concept of a folding screen portable long ago, back in 2001 if I remember correctly. (Sorry folks, Nintendo didn't invent the hinge along with the DS) Above is a sketch I did on a PDA (and still have in my Outlook notes) Originally it was going to have fold-up "joystick handles" with a D-pad on the left and a trigger on the right. Cut to 2006 and I get the urge to build one again, for a person wanting an Atari portable.
The first step was to cut down an Atari 2600 motherboard into a small shape that still worked, as seen below. The resulting piece is the same width as the standard 4" x 4" I cut them into but is about 1/2" shorter in height. This required me to attach all the cartridge wiring to the data and address bus locations on the chips. I used thin, solid-strand Ultra ATA hard drive wire for this, though for the power and ground connections I had to double up the wires to provide enough current (learned that from the old Vagabond 2000)
Strangely enough, though I've tried at least 3 times, I've never been able to wire an Atari 2600 "by hand". That is to say, starting with the 3 chips and connecting them on a breadboard so as to "build" an Atari 2600 circuit. If I had a normal job and normal free time I'd definitely try it again, but alas...
Next came the design. 2006 will go down for me as the "Year of Hinges" Originally I wanted to make this thing look very old, using wood grain, the color yellow and silver knobs. Spent a few hours browsing online TV museums looking for 1970's era inspiration (though I'm typically more interested in the post World War I mechanical television) Finally I said "screw it" and made this thing white like every other piece of electronics these days. But I did slap on some text reading "Solid State Transistorized" since I am old enough to remember when things actually advertised that.
Aesthetics aside, I did have some trouble positioning everything and keeping it small. The d-pad and trigger had to fit inside the upper portion when closed, the cartridge of course takes up way to much space and there still had to be room for (4) AA batteries and an auxiliary power port. I came up with the idea of having the Atari guts themselves in the lid along with the 3.5" LCD screen and audio controls. The ribbon cable would connect the two halves for not just the cartridge, but also power and game controls.
I cut the case out of black acrylic with engraving plastic plates. All the text was laser-etched into the surface in my continuing move away from decals. Above you can see the control portion with the hollow D-pad in place. The tact switches (see below) fit inside the D-pad and buttons rather than below them. This makes the unit thinner (or rather, less thick)
Below is shown a control module. It has the tact switches and one of the battery packs.
This next photo shows how the rebuilt cartridge slot fits into the base of the unit. Since the older Atari cartridges had little "doors" that have to be pushed open with tabs, I used 2" long screws to both hold the cartridge connector in place and poke open the doors.
Another view of this, with the main Atari board tucked below.
Top of the unit before the lid is screwed on. The thing in the upper left is a tint control knob. This unit also has a headphone jack along with an amplified internal speaker.
Here's an end view before the 2 pieces of the base were screwed together. I designed the case in such a way that little doors slide over the batteries. The battery holders keep them in place just fine, but it looks better to hide them.
Some photos of the finished unit:
OK so that about covers the construction of this unit. Remember you can check out my book to learn a lot of these techniques. Now let's get down to brass tacks, because I know what a lot of you old-time followers of Benheck.com REALLY want to see. So without further ado I present...
