In about twenty four hours eleven people have signed up for 13 PC boards.
This is far more than I ever expected, and I'm glad to see so many people
interested in PDP-8s and the SBC6120. I plan to keep taking sign ups until
Monday, or we get to 20, which ever is first.
BTW, the number of people signed up for our cooperative so far is enough
to guarantee a PCB price somewhere in the low $30 range.
Thanks again,
Bob Armstrong
