Erik Klein at the 6th Vintage Computer Festival

Hello all,

Back in the late 1970s I was a fairly typical Jr. High School kid with probably a bit more knowledge about computers then most. My father was an Engineer for IBM and, eventually, other companies and always had a ready supply of Byte, Microcomputing, Creative Computing and Datamation magazines lying around for me to read. This ability to at least "talk the talk" had an impact on the kids I associated with and the activities I ended up involved in.

Then, in 1978, after spending hours at card punches and 3278s at dad’s office, I bumped into the first computer I could relate to. The school district had purchased a Commodore Pet for the younger kids to play spelling and word games on. I managed to get a little after-hours access and I was hooked.

In subsequent years I took a variety of computer classes, attended a "computer camp" hosted by NY State University and continued to putter around with whatever machines I could get my hands on. The school district had a PDP-8 as well as the Pet and, eventually, they purchased some other machines.

By 1980 I had established myself as a full-fledged, card-carrying geek and I was pushing hard to get my own computer. Of course, at 14 you can't expect much but I saved my pennies and looked for opportunities. By the summer of 1981 I was close to being able to afford my "dream machine" of the day: An Atari 800. I felt that it was a better machine then the Apple ][ and I could probably get a better deal on it.

When the time came to empty my piggy bank and actually buy the machine my dad intervened and offered to buy us both the just recently introduced IBM Personal Computer. I reluctantly accepted this deal but then suffered the months in waiting for that box to arrive. Finally by December 1981 the machine was set up and running a variety of little games that I’d written to amuse myself and my brothers.

In early 1982 I became one of the founding members of the Long Island PC Users Group (a SIG of the Long Island Computer Association) and, by default, one of the club officers. I contributed to the club newsletter pretty much every month and eventually ran the clubs BBS until I started college and was forced to turn it over to another. I later ran another general purpose BBS for a time.

When IBM introduced DOS 2.0 the club offered a seminar to the community to raise some funds. I ran a couple of sessions including the introduction to BASIC 2.00 and the new features added to the language. That seminar got me my first “real” computer job and lost me my paper route. I then spent the next six years or so trying to convince myself that I didn’t want to work in computers because that would ruin the fun for me. While I wasn’t too far from the truth, I did fail to convince myself and, after paying my way through college with various programming jobs I started a career in software that still pays the bills.

During my career I’ve programmed in a variety of languages including Visual BASIC, COBOL, FORTRAN, C and C++, BASIC, PowerBuilder, Clarion and Gupta SQLWindows. Projects have ranged from simple word processors to vehicle tracking systems to a variety of medical applications.

A few years ago I bumped into eBay and started nostalgically browsing around their vintage computer category. The end result is the functional equivalent of a heroin addiction that costs less but takes up more space. I started collecting old computers. Specifically I collect old PCs. First just the machines that had a particular history with me (the Atari 800 I once coveted, the Apple ][ Plus I learned BASIC on, the IBM PC I first owned, etc.) and then it became any machine I remembered reading about, playing with or regarding as cool at one point.

Today my still modest collection numbers over 50 machines; most of which work well and have original documentation, software and, in some cases, original packaging. Most of these machines are proudly displayed on this site. The ones that aren’t eventually will be.

I am also using the website to host The Vintage Computer Forum, a discussion board to help foster the community of computer collectors worldwide and the Vintage Computer and Gaming Marketplace, an auction site for vintage computing enthusiasts.

Thanks for visiting!

Hi Erik,

Erik, Well done on all counts with the site and your collection. We are about the same age and my story is similar to yours, I wanted an Atari 800 but dad got me the Apple IIe. I also used to progam on Texas Instruments using Logo at school (great softwre tool that). I have total respect for what you have done here.

Like you, not only does programming pay the bills, there is still nostalgia about it. Based on what I have read on your site I am going to go find me that Atari 800 on eBay!

Cheers, Charlie

Greetings Erik (my middle name too): Very nice and very helpful site, eBay should take a cue from you and list the obvious questions and answers any struggling newbie would be begging to learn regarding old collectible pieces of iron. I'm so glad I stumbled over your nuggets of IBM 5150 information instead of leaving me to dangle on eBay from now to eternity. Thanks again dude, you're a hero as far as I'm concerned. You gotta very nice and easy-to-use site and a lot to be proud of.

Hi Erik. I am looking for the first ever advertisement for JD Edwards software. The company was founded in 1977, and their first packaged product was called Upstream Accounting, and geared towards the Oil & Gas Industry. I don't even know what magazines would publish such ads, but it would probably be in the same realm as SAP, Baan, Peoplesoft etc. I figured a geek of your caliber should be able to help us out.

You have a very nice collection Eric; the most complete I've seen. Two ideas: a) make a virtual tour of your computers, navigable from cyberspace, and free b) using a little startup money, rent some space in the Bay area and open a computer museum. Charge admission to cover your costs, and enough to pay for a staffer so you can continue your computing career with the museum being self-supporting. If you make it non-profit, and then you can accept (corporate) donations to keep admission prices low. Best of luck, Matthew (in Toronto)

Hi. I would like to know if I should trash this computer or try to find it a new home. It's a Motorola EXORset 100, still in working condition with two 5,25 drives and software.

Erik I noticed you have an 'unknown' under ROM size for your PETS. It's in 2k blocks, in 24 pin chips (you can't miss them!) I'm going from a long way back, but the 2000 and 3000 series had 4 roms (8k) and the 4000&8000 have 5 (10k) to handle the extra disc functions. The other spare sockets were for eprom tookits. 2 on the 4000/8000 and 3 on the 2/3000. By the look of it, you have the toolkits installed on your 2000 model.(no spare sockets) Chris

Thanks for taking the time and exerting the effort to build your interesting and educational website. I retired from programming in 1998 after 34 years, so it was particularly nostalgic and entertaining for me.
