Boards should be available already assembled in a couple of weeks.
I'll let you know as soon as I have more details

I had considered the LPC1768 in place of the STM32F103 when I started
to design Lisa. I chose the STM32 because of the nice peripheral lib
and also because it's available in numerous packages (for QFN36, to
BGA64, BGA100 up to huge QFP 144). For exemple I am designing a servo
driver board based on the same STM32 but in a QFP48 package and a
small version of Lisa using the BGA64.

At the moment, the Booz code is happily running on Lisa/L in the STM32
and the poor MCU  is very bored.
