Yeah. We actually bought one, but the problem is that most modern plcc parts
require 3-3.6V to flash, and this programmer needs an additional voltage
adaptor to do that (it uses 5V if you hook it up to your PC power supply).

I don't suppose there is a manual in English somewhere? My German is rusty

Suggestions on how to build/where to find such a voltage regulator? The
manual isn't very helpful in that respect - at least as far as I can make
out. Would adding a resistor to the +5V line be sufficient?
