[sdiy] how you got started with your current µC?

[Dave Brown]

I started programming on a PDP-8 in assembly language.  My first micro was
an 8008 in 1974.  The system was an Omron terminal that had a debugging mode
so I could use a DEC-like ODT to create machine language programs.  We had
some 6800 development boards in the lab that I could do the same with.  Then
I got to design an 8080 system in 1976.  I had an Intel ICE unit for
development and wrote in assembler.  From that I went to the Z80, 8085, and
80186 with a variety of O/S but most was CP/M.  For the 80186 I wrote again
in assembler and some in PL/M.  There was a quick stint with the TI 9900 in
there and also a 2901.  Then I started doing more embedded programming with
the 8041, 8042, 8048, and 8051 variants, again in assembler.  Then 10 years
ago I decided to try the AVR Synth and needed to buy the development system.
So, for any of my smaller micro projects I have continued to use AVR.  It is
probably time to move on to some other core.

 

I always wanted to do an Intersil 6100 project so I could do PDP-8
programming again.  I thought about the PDP-8 recreation but realistically
what would I have done with it?  I do have a Big Board and a KIM-1.  Every
now and then I will key in a clock program into the KIM-1 and that lasts
until we have a power outage.  At the vintageTEK museum we have some systems
built around the Motorola 88K, 68K series, National 320XX, and some
bit-slice 2901s.  The latter should be one of my next repair projects.
