Z80.
This is a Sol-20 personal computer made by Processor Technology. First released in 1976, it utilized the Intel 8080 8-bit microprocessor chip, running at 2 MHz. It was notable for being the first personal computer for including a built in video driver so users were not limited to serial port based terminal systems.Show Image(https://dl-web.dropbox.com/get/Camera%20Uploads/2013-11-11%2021.06.39.jpg?w=AAAWnWRZ8uixP0oQNz7VwMylmrCoVhYrUjw4Nc-QHx6CfQ)
This photograph was taken last Monday at a reunion of the Homebrew Computer Club which I was fortunate enough to attend. The paper taped to the front reads "pull out the guts & screw with the brains"
Does anyone else keep vintage computers around and have photographs of them?

ha! mine had a 3.5mhz cpu! and a ****en plenty of 48kb ram!My first computer had a 1.79MHz CPU.

Can't see the pic, but that's awesome. Was Lee Felsenstein there? Did Woz show up?
Always wanted an Altair, always too expensive. I think there are a few replica kits out there now, but they are also quite costly! And all so I can experience computing at its worst - flip switches and blinking LEDs. There's just something really geeky-cool about that to me.

My first computer used a 16-bit TI TMS9900 processor @ 3.0MHz, with 256 Bytes of "scratch pad" RAM and 16 KB VDP (graphics RAM).

I recently bought one on eBay, but I don't plan to use it as-is. My plan was to use it as a housing/keyboard for a Raspberry Pi. :)

TRS-80?
Lee Felsenstein was there and moderating the discussion. Woz was there and spoke briefly about the social mission he felt behind the personal computer.
Did know any other GH'ers were going to be there- HaaTa and I were also there!

One of these days I'll get enough working to organize a retro hack day.

I'd actually met Woz previously at a similar function some years back and didn't feel up to making my way through the gaggle of people around him. If you ever do meet him don't be shy. He's a phenomenally friendly person!
Toggling data into a computer is novel for about 40 switches, then you lose track and get over it. When I first saw cookie clicker it actually kinda reminded me of toggling switches only brainlessly.
If you ever make it to the San Francisco bay area the Computer History Museum in Mountain View has a pretty fantastic setup. Make sure you go on a Saturday so you can see the Babbage Difference Engine in use!

Man, that meetup sounds like it was awesome. Don't suppose you have any more pics? Thanks for the share!
I'm actually around the bay area but haven't gone to the Computer History Museum in years. I should really go. There's also the Living Computer Museum in Washington that looks way cool.

Just this other crappy cell phone picture I sent to my coworkers to make them jealous.Show Image(http://dl.dropboxusercontent.com/s/kc0rw50p2u8fdd1/2013-11-20%20at%209.45%20PM.png)
When the professionally shot photographs make it on Flickr I'll link them back here.

My first comp too! TI-94...Did you ever connect a tape player to load software? lol...If you remember that, then you know.
Of course! I had a tape recorder and the little cable to connect it. Then you had to type LOAD "PROGRAM_NAME" at the prompt to load it and then RUN to execute it once loaded. :)oh yeah.
