I hope I'm not in trouble for double posting. After I posted this to a thread in "First Boot Problems" I thought it might be better to put it here. I'm just found the site because I had a problem with my latest build and Googled for a forum that might help. There are lots of good tips in this forum. Here is what I posted in the other thread:
My first build was in 1977 0r 1978. In those days a build consisted of soldering the chips onto PCBs, building the PSU, the "slots" on the mobo, etc. The CPU was a Motorola 6800, 8 bit processor. The basic "kit" came with 4K of RAM that I upgraded to 32K. That was the max because the IO was memory mapped and started at the 32K boundary. At first SW and data were stored on a cassette tapes. A few months latter I bought an 8" floppy disk drive that set me back $1500 at a time when gasoline had just sky rocketed to $.50/gal. There was no OS, the few apps ran as stand alone programs. That were written in interpretive BASIC. I had a Xerox daisy wheel printer with a KB that I used as a terminal. Later I got a Adam-3 ASCII terminal. It displayed 80 char/line and no graphics.
