If you want to see a Mimeo in the flesh, my son and I have lent one to MARCH/InfoAge for an extended period. While I will still be showing another one at my VCF East exhibit, I brought this one over early so that it can be part of the normal exhibits at the Museum for a while 
For directions an Museum hours if you can't make it to VCF directions to MARCH/InfoAge is here.
