    Wow, I love it :!!)! Especially the chicken scratch on the "APCO Air Valve Computer"!

    You should have turned the Casio over for the second photo :biggrin:.

    I threw away all of my old computers and handhelds, well, most were destroyed in a flood. I had a Cassiopeia, way back when. In my last move my old Sun Microsystems computers got "lost".

    I'd love to have an old Sun. When I dug out my 6 digit computer (Casio), that had been in a box of junk for probably >35 years, still had 2 AA batteries in it and when I switched it on, several of the blue number segment lit up.

    I still have one of those 100% metal computers. I lost my 100% bamboo one some time ago. The bamboo one was of course better.

    I also have some parts from Symbolics machine #2. Non-functional, but still rather symbolic of the AI phase of my career.

    I have my old sliderules still, both bamboo, both LogLog DeciTrig with one 12" a long rule and the other a pocket rule. I also have an addiator and a Concise circular sliderule with a tiny scientific cheatsheet pullout with a bunch of facts, conversion factors and a complete periodic table.

    For electronic stuff, an early HP handheld and a TI SR-50 that works really slow by todays standard.

    As a teen I had a Digicomp, a mechanical 3 bit computer, but I think my Mom sold it in one of her legendary garage sales. Now on ebay they can be had for $200 or more depending on the quality.

    dlgoff, I can't see the images. How old is your computer collection? Are you planning to sell it?

    Maybe they're theoretical. No images seem to have survived in this thread.

    dlgof is here almost daily, maybe we can get him to fix the images :)

    Wow, that brings back memories! I had one of those too, but I think I was a bit younger, maybe junior high school (middle school). I remember being intrigued by it, but I don't think I actually learned anything about bit-level computer logic from it. I think that didn't happen until I actually had to teach some of that material (the different kinds of gates, etc.), after more than ten years of experience in Fortran programming.

    The images were uploaded to ImageShack.us as a free service but now they want a monthly membership fee and have hide them unless I pay. I'll try to upload them to my new image hosting site. I'll have to find them first.

    @ jmneutr0nn3. These computers probably aren't the kinds you're thinking of though. :)

    So that explains other images that are missing from other threads. I think I saw a lot of them on flower and animal lovers threads. They don't appear no matter how many times I refresh the page.

    I was going through some of my old boxes and found my first computer. It came with a speech synthesis kit that Bell Labs was handing out to those interested. They had set up a booth at our little towns annual carnival. Thanks Bell Labs.

    My first computer was a Commodore Vic-20. My mom bought it for me in 1982, I think, when I was 14. I remember thinking, what the hell am I going to do with this? I don't think "hello world" was around then, but I followed the manual and ran a goto loop and printed something on my TV through the RF receiver, and, of course, I was hooked instantly. I bought a book entitled, "Programming the 6502," which came with a handy schematic of the processor, and learned that computer from the inside out.

    I even breadboarded a memory expansion to it. It only came with a few kilobytes, and to get a few more you had to buy this cartridge that plugged into the back for something like 30-40 bucks. It was a long time ago, but I think I just bought a few static ram chips at radio shack and got the same amount of ram for about 5 or 6 bucks. Me and a buddy of mine were going to go into the memory business after discovering this but got sidetracked with adolescent issues.

    I don't still have the Vic-20, but I have the original breadboard memory expansion prototype and a few photoetched circuit boards in storage somewhere. Lol.

    Was there there some kind of Einsteinian "Power-Energy equivalence theorem" back then that you old guys have since covered up?

    Awesome. Love it. I'm guessing the language was BASIC? Do you still have the book?
