Bill, over at Prairie Point has provided me this little link for a very retro phone. The little black bundles of communication fun are not cheap - $399 for starters - gak. Readers will remember I posted a few days ago about such a non-working Ma Bell device here. Only ours is a tad bit older than the model shown at the SparkFun site.
The only thing missing from these babies is the dial tone and the anchoring tether to a wall jack.
