Charles C. Childress, a doctorate of biochemistry, founded the company as a way to market his data acquisition and processing interfaces based on programmable calculators for medical, scientific, and industrial uses. After an after-market floppy drive system for the SWTPC 6800 proved a hot-seller for Midwest in 1976, the company began products for general-purpose computers like the SWTPC. In 1977, they released their own microcomputer, the MSI 6800—a clone of the SWTPC 6800. Their sales tripled that year, and the company thrived well into the '80s before shutting down. \u003cimg class=\"alignnone size-full wp-image-608\" src=\"https:\/\/psyne.com\/wp-content\/uploads\/2025\/11\/ebay-spacer-1.png\" alt=\"\" width=\"1275\" height=\"16\"\u003e \u003cstrong\u003eProduct Details\u003c\/strong\u003e\n\n\u003chr\u003e\n\nLike all our designs, this one is treated with our signature ‘relic-ing’ process which includes our own secret recipe of hand-painted chipping, cracking, fading, and just the right touch of yellowing to ensure that it looks the part of a true vintage imprint.** We lay these works of art down on premium Bella+Canvas 3001 Unisex Jersey Short Sleeve Tees, one of the softest, best-wearing t-shirts available today, via state of the art direct to garment (DTG) printing which allows us to create a vintage effect that simply can’t be accomplished with other printing methods.

We recommend taking one of your current t-shirts, laying it flat and measuring it. The measurements in the chart below are taken with the shirt laying on a flat surface. To get the length, measure from the high shoulder point down to the bottom of the shirt. To get the width, measure approximately 1-inch below the armhole, across the chest, from seam to seam. While our tees are all made using premium, pre-shrunk, ring-spun cotton, there can be some shrinkage depending on your personal wash and dry cycles. With that said, if you’re on the fence, we always suggest going up a size. \u003cstrong\u003e\u003cimg class=\"alignnone size-full wp-image-608\" src=\"https:\/\/psyne.com\/wp-content\/uploads\/2025\/11\/ebay-spacer-1.png\" alt=\"\" width=\"1275\" height=\"16\"\u003e\u003c\/strong\u003e\u003cimg class=\"alignnone size-full wp-image-606\" src=\"https:\/\/psyne.com\/wp-content\/uploads\/2025\/11\/ebay-size-chart.png\" alt=\"\" width=\"1275\" height=\"220\"\u003e \u003cem\u003e\u003cstrong\u003e\u003cimg class=\"alignnone size-full wp-image-608\" src=\"https:\/\/psyne.com\/wp-content\/uploads\/2025\/11\/ebay-spacer-1.png\" alt=\"\" width=\"1275\" height=\"16\"\u003e\u003c\/strong\u003eAll sizes are provided in inches!
