Awe! Jack Zylkin got back to me ASAP and emailed me the following:
"Thanks for your enthusiasm about my invention! Unfortunately, I don't think the kit will work on a Hermes, because the Hermes has a solid steel frame underneath it -- you can't access any of the mechanisms without taking apart the typewriter. Sorry!"
(That's okay, Jack. Thanks for letting me know. Thank goodness he let me know about it right away. Guess I better tell Gary. Man!
Only way I can get a USB Typewriter is by cheating on my Hermie. I can't do that! Can I? Is owning two Typewriters over-kill...because I do find underwoods attractive...? Sigh. I may just bid on one on eBay...and get the kit... blah. Why can't stuff be easy. Or am I making it complicated? Too bad OCR doesn't let you edit... I do have my Doxie coming...
