       | Really enjoyed this writeup. I'd come across Don Tarbell's name
       | before, but didn't realize how influential he was in the pre-
       | Altair era--and even in setting the stage for the Apple I.
       | Fascinating stuff.
       | 
       | I also wasn't aware of this site--some really well-researched
       | essays on early computing. Great work, and thanks for putting
       | this together!

         | I've always been fascinated by the history and technology of
         | microcomputers. It's similar to how enthusiasts feel about
         | classic muscle cars. With microcomputers, you can understand
         | every aspect of the technology, from the transistors and gates
         | on the silicon to the components on the board, and all the way
         | up to computer languages and the user interface. It feels like
         | I could work on any part of it with just a bit of time. My
         | daily driver is an M4, and I find any new trend in computing
         | worth exploring. However, my retro computers always keep me
         | company.

       | A recent (2014) and intriguing concept for making a small
       | computer that feels like it was made in the past is the
       | PDP-11/Hack, which only uses a DEC J-11 microprocessor, some RAM,
       | and a common UART.
       | 
       | The original concept By Brent Hilpert:

           | I bought a DEC J-11 for $45 on eBay, the maximum price I saw

         | This being the PDP-11, even if you don't have any RAM, I'm sure
         | the registers are mapped into memory somewhere contiguous where
         | you can still run code from them :)

       | Probably deserves it's own post.

       | What an exciting time for the industry. Most of the companies are
       | run by 20 or 30 somethings. Nobody has a plan for success.
       | Everything is poised to explode once someone, anyone, figures out
       | how to deliver product at scale. This also makes it clear how the
       | software guys got so big so fast: making new copies of software
       | is trivial compared to hardware manufacturing.

       | Brings back memories. My first computer was a Heathkit-branded
       | PDP-11 kit my dad assembled, with a dumb terminal, paper-type
       | I/O, and no operating system. Later we had dual 8" floppies and a
       | version of DEC's RT-11 OS, which was similar to CP/M. Read Byte
       | magazine, and grew familiar with the names Altair, MITS, SWTPC,
       | Imsai, etc., etc. Good times.
