This device can be plugged to LPT port of PC
It’s a additionary tool for testing device for microprocessor tools. As you know, sometimes processor at testing systems can stock, even when in theory everything is ok.
First element of that tool is highvoltages concurrent programmer, that comes from It can be controlled by AVRPP.EXE program.
At the board we have two legs for processors, 20 pins (2313) and 28 pins for ATmega8. There is also place for ATmega16/32 in Dip and SMD version. You can easily add new processors, by putting DIP20 leg.
Programmer consist power generation system +12V from +5V. if we don’t have any similar.
Second element is serial programmer ISP STK200
Third element is digital analyzer. It allow to test 8 digital paths, ot 2 with voltages between 50mV to 5V (sensitivity of potentiometer) and six TTL paths. For progress analysis we may use software from

Thanks to A/P switcher, we have full control at each blocks.
To start serial programmer we use package of jumpers that are glued together, that causes blockage of the STK200 programmer
Device is connected at one side to PC by LPT slot via printer cable. At second side, by ISP programmer slot. Device can be use as a separate panel.
At
