Hi to all.
I joined recently after rediscovering all my computer stuff that had been largely forgotten in the corner of my basement.
That's what living in the same house for over 36 years and then moving to a new home will do.
I am an ex DEC field service engineer (1979-2007) in the Milwaukee area.
Unfortunately, I did not discover VCF soon enough as I threw out a lot of what I thought at the time was just junk. So sad.
My profile picture is of the first and to this date, the only home brew system I built, from the late 1970's.
It is loosely based on a Motorola development kit from the tech school I went to, but I used a 6802 instead of 6800 since it had 128 bytes of on-board RAM !
It is very basic and all wire wrap.
The less populated board contains the CPU, static 2114 RAM, serial IO 6850 and parallel ports 6820.
The other board is video, basically built directly from the TV Typewriter Cookbook.
The EPROM contained a self-authored simple interface that allowed the input, output and running of machine code via the keyboard and TV screen.
I had no real long term plans for it. It was just a hobby.
I did buy a cheapo acoustic modem kit and actually was able to login to sites with a simple send/recv program thru the 6850 UART chip.
I have to laugh every time I see this picture since I only used wire wrap gauge wire for the power supply connections !
Anyway, hope to contribute a little here and there along the way, but mostly looking forward to enjoying the various discussions, DEC subjects in particular.
