I've got another Quickstart module in the works which incorporates a PS2 connection.
Did some testing to determine if it was possible to power typical PC keyboards at 3v.
I thought I'd share my results.
{Test unit was a Quickstart with QuickAdapter to PP Proto Module with breadboarded PS2 jack.}
{Standard PS2 demoboard type circuit used.}
Success rate with PS2 keyboards appears to be around 50%
The successful keyboards were the more common (for me) PS2 keyboards.
