Way back in 1974, as a 22-year-old in Louisville, I started a small electronics business called Cybertronic Systems to help fund my growing microprocessor addiction and begin my escape from the employment treadmill that was already looming as a dangerous life habit. Within about a year, I was doing enough sales out of my apartment…

This Feghoot has been languishing in my old paper HUMOR file for decades, copied from a mid-70s issue of The Isolated M, a little ‘zine published for remote Mensa members by the late Harper Fowley of Louisville. (I proudly wore my fan club badge above to the occasional meeting, back when I was a pup.) I…

My favorite correspondent back in the Olden Days was my old friend Steve Orr, whom I met during my brief sojourn to Rose Polytechnic Institute in 1969. The file folders that we both kept all these years have yielded some interesting historical documents. This one is slightly silly, but revealing…   Letter to Steve Orr by Steven…

I’m very fond of this piece from an obscure magazine published in Louisville in 1975-76. I believe only two issues were ever produced, and it was founded by Ernest Johnson, David Caudill, and friends. What I find fun about this is that it captured a glimpse of my life long before the bike, and even…

When I was 23, I began the second year of my mail-order electronics parts business, operating out of a 2-bedroom apartment in Louisville. This was profoundly liberating, especially as I had just taken the huge leap of quitting my job as a field engineer for Singer Business Machines. My own work was much more exciting; I…

This is a minor bit of history – about a month after my 8008 first came online, I added a rudimentary hand-assembled editor to CYMON (Cybertronics Monitor) and used it to send a letter to my friend Steve Orr in Cincinnati (who scanned this document in 2018). The teletype hardware interface was described in my Electronics…

Roberts October 31, 1974 Below are the original schematics of the homebrew computer I built long, long ago… an 8008-based machine that resides in the Computer History Museum (that link will open in a new window and show you four professionally done, zoomable photos). The six…

by Steven K. Roberts January 9, 1974 It is hard to put into words the blazing intensity of my obsession with microprocessors in late 1973. I close my eyes a half-century later and can still FEEL them, little gold/ceramic dual-inline packages exponentially more capable than the simple logic devices that had become my creative toolkit.…

Looking at these ancient photos now, I can see why I often got “written up” after room inspections. My bed, not shown here, was a crawl-in cave behind the workbench, and I had a cat named Bolivar living with me. The tall equipment rack was a homebrew HF transmitter with a pair of Eimac 100TH…

I had an oddly contentious relationship with my superiors in the Air Force, long ago, when I was 19 and obsessively building a lab into my dorm room. In the middle of all that, a friend bought a new motorcycle and invited me to go for a ride… an adventure that led to a broken…
