Wanna have an idea how happy the last posts about floppy drives and this lightpen upgrade makes me feel?
It puts a smile on my face as big as Dr. Phlox shows here: http://images3.wikia.nocookie.net/memoryalpha/en/images/b/bf/Phlox_grinning.jpg
Thanx soo much for doing this
Peter.

Thanks all for the kind words and encouragement!

So far it looks like there is interest in 10 units total (including 2 for my own use :-). I'll get a few extra boards.

I'm making some changes to the layout for the next rev of the PCB. This is mainly to correct a few errors in rev 1, but also to add an RCA jack for a simple composite video output. (Those 5-pin Cannon connectors are expensive!)

I am planning on also doing a version for adapting USB keyboards to the I/II/IIx (and CVI), and for emulating the Series III keyboard and G-pad.

I'd also like to thank my friend Joe Sleator for his invaluable help brainstorming via email during the development of the adapter! :-D
