Hi, No criticism of you effort intended, but I am working on a semi-automatic punch. If it works to my satisfaction by then, I'll have it with me at VCF East ...
Thanks Bill! Are you offering your punch as a kit or for sale? I think it would be very handy for those of us with old hard sector minidisk computers like...
