Can you really offer these at $15, with *plated edge connectors*, all
drilled out - and still cover your costs? Maybe you can make some
boards (of my design) for ME on those terms! We can talk privately
about stuff like that (after the upcoming VCF show).
The only downside to your vertical runs of chips is that it limits
chip count. Some protos are horizontal runs, some are perforated at .1
centers on the whole board. I'd prefer the whole-board perforated
design, and run my own grounds and power, for maximum flexibility. But
for a simple design using a dozen to 20 small chips, or a few large
chips, your board will do the job.
So good luck on your project! Keep me posted.
