I'm a computer guy. I've been fascinated by them since I was a little kid back in the 60's (that's the 1960's, for you Millenials who are math challenged). It only makes sense. I grew up in the glorious era of American achievements in science and engineering. We were racing to the Moon. The astronauts and the engineers building the systems that sent the astronauts into space were our heroes. And computers were everywhere. We kids were made to understand that American prowess in raw computing power, along with American drive and excellence in aerospace engineering, were what was pushing us forward in the race to beat the damned Russkies - at anything.
But in the 1960s a computer would quite literally fill a room. Or two. Computers were fascinating in concept, but unachievable in reality unless you attended a well-heeled school that provided access to a computer (usually via a time sharing system), or were one of the lucky few who's parents or relatives worked in a job that provided access to a computer. My first direct access to a computer didn't come until the mid-1970s when, in college, I had to run some insect-borne disease infection models on the university's IBM mainframe system. You'd go to the computer room window and tell the geeks what simulation you needed to run. They assigned you to a terminal while they pulled the card deck, ran it through the card reader, gave the computer time to compile the program and then sent you a notice through the terminal that the program was ready to run. These terminals were nothing more than a teletype-like keyboard and printer - no CRT interfaces for us low-life undergrads. You knew the program had successfully compiled and was ready to run when the teletype gave you two dings and chugged out a 'READY' line of text on the fanfold paper. But it was glorious! The entire resources of that behemoth behind the window were at your disposal. You could change variables on the fly, run looped simulations to test exponential increases or decreases in vector transmissions, and watched as your test populations of disease victims either survived or died based on various insect control measures. The experience sticks with me today, not because I couldn't kill enough mosquitos and repeatedly wiped out over half the population of some notional West African country, but because those sessions gave me direct access to a computer program that allowed me to control the multiple related variables and provide real-time feedback. I was hooked!
Unknown to me at the time, there were forces at work in places like Silicon Valley that would upend the computing paradigm and create the concept of the 'personal' computer. When I became aware of this sometime in the late 1970s I became fascinated with the concept but could only participate on the margins - most of these 'personal' computers like the early Apples or CP/M systems cost almost as much as a new car. My first computer was the $99 dollar (that's 1981 dollars) Timex/Sinclair 1000. Oh, and the additional 16k memory module was an additional $99. That's almost $600 in today's inflation adjusted money. But hey, it was real computer! A somewhat crippled computer, yes, but at least it had a real CPU, a video driver, could load and save data and programs on a tape drive, and had built-in BASIC.
Although I was not a computer science major, my professional career with the US Army Corps of Engineers kept me in close contact with computer developments. We transitioned through a wide variety of computers and operating systems as our software applications matured. The list of systems I worked with reads like a pantheon of personal computer and workstation development - Commodore 64 & Amiga, Apple IIe & MacIntosh, DEC VAX (various models), SGI Indigo, HP/UX (various hardware platforms), Wang, Sun Microsystems, GRID and of course the various iterations of IBM PCs and clones - Kay, Compaq, Gateway, Dell, Heath/Zenith, HP, you name it. I have lived the arc of personal computer development, and it's been a fascinating journey.
A year or two ago I became aware of a museum here in the Atlanta area titled the 'Computer Museum of America'. It appears the museum is an extension of the collection of Lonnie Mimms, a commercial real estate developer and avid life-long computer collector. I suspect much of what's in the museum came straight out of Lonnie's garage. So yesterday the XYL and I took a few hours to drive up to Roswell, GA to visit the museum. Suffice to say, I had a great time and was delighted to visit with some 'old friends'.
